INTRODUCTION
The Philippines, situated in Southeast Asia, is an
archipelagic country consisting of 7 641 islands divided
into three Luzon, Visayas, and Mindanao Island groups,
where Luzon and Mindanao are the two biggest islands.
The Philippines is bordered by the Pacific Ocean in the
east, the West Philippine Sea (formerly called the South
China Sea) in the west, Taiwan in the North, and Malaysia,
Brunei, and Indonesia in the South. It has a total territorial
water area of 2 200 000 km2, including an exclusive
economic zone (EEZ), with a coastline length of 36 289 km

(BFAR, 2019). It is seated within the Coral Triangle a
significant hotspot for coral reef biodiversity (Carpenter &
Springer, 2005; Muallil et al., 2014).
Philippine Fisheries is acknowledged in world
fisheries as one of the major producing countries. In 2018,
the Philippines contributed to world fish production,
amounting to 1.89 million MT (2% of the marine capture
production), and ranked 13th worldwide. Similarly, the
Philippines is the 4th major seaweed producer globally
(FAO, 2020).
There are three fisheries sectors in the Philippines:
aquaculture, municipal fisheries, and commercial fisheries.
In 2018, aquaculture accounted for about 53% of the total
production with 2.3 million MT, where seaweeds, milkfish,
tilapia, and shrimps/prawns were the major cultured
species. Municipal fisheries constituted 25% of the total
production with 1.1 million MT, while the commercial
fisheries sector contributed about 946 thousand MT of
production comprised 22% of the overall fisheries
production (BFAR, 2019; PSA, 2019).
According to the Philippine Statistics Authority,
the country has a population of about 101 million in 2015.
Fish and fishery products are the principal protein source
for every Filipino consuming 37 kg year-1 comprising
about 12% of the total protein intake (BFAR, 2019).
Fisheries provides a livelihood to almost 2 million
coastal dwellers. Fisherfolks were engaged in different
fishing activities such as capture fishing, aquaculture,
vending, gleaning, fishing processing, and others. Of these,
capture fishing and aquaculture employ the most with 49%
and 11%, respectively (BFAR, 2019). Fisheries activity is
not only carried out by men Filipinos but also women .
Gender participation plays a crucial role in the fisheries
sector. For instance, in Taal Lake, Luzon, fisherfolks were
represented by 54% male and 46% female consisted of
fishers, processors, helpers, and fish cage or fishpond
owners, managers, and caretakers (Mutia et al., 2020).
Fisheries is crucial to the export earnings of the
country. In 2018, the Philippines earned about US$1.6
billion. The country's major fishery exports were tuna,
seaweeds, shrimps/prawns, crabs, octopus, grouper, round
scad, cuttlefish and squid, sea cucumber, and ornamental
fish (BFAR, 2019).

PRODUCTION TRENDS
Five-year (2014 to 2018) Philippine production from
the three fisheries sectors is shown in Table 3 and Figure
2. Aquaculture production is consistent with more than 2
million MT and remains the primary Philippine production
source compared to municipal and commercial fisheries in
5 consecutive years. Municipal fisheries production is
more or less unchanged throughout the years, with more
than 1 million MT. However, commercial fisheries
production gradually declined from more than 1 million
MT to more than 900 thousand MT in the same years (PSA,
2019).

and 2018 (PSA, 2019).
SECTORS OF PHILIPPINE FISHERIES
Aquaculture
Aquaculture is a significant contributor to the
country’s total fishery production. It is the lone sector
where continuous development has been achieved
compared to the municipal and commercial fisheries
sectors (Aypa & Baconguis, 2000; BFAR, 2019).
Seaweeds (mainly Kappaphycus and Eucheuma spp.),
milkfish (Chanos chanos), tilapia (mainly Oreochromis
spp.), and shrimps/prawns (Peneaus spp., Metapenaeus
sp., and Macrobrachium sp. ) are the top cultured species
produced from the aquaculture sector, comprising 91.38%
of the total production in 2018 (Table 4) (BFAR, 2019;
PSA, 2019).

Major Cultured Species
Seaweeds: Seaweeds are a vital marine ecosystem
component alongside the mangrove and coral reefs. They
can be seen in two viewpoints, from their ecological value
as well as their economic benefits. Among the flora in Asia
Pacific Regions, the Philippine seaweed is exceptionally
diverse (BFAR, 2010). As compiled and published by
Silva et al. (1987), seaweeds recorded to be up to more than
800 species. The Philippines' seaweed sources have been
extensively reviewed by Trono & Largo (2019),
emphasizing that Kappaphycus, Eucheuma, Gracilaria,
and Caulerpa as major cultured seaweed species.
Additionally, Codium, Gelidiela acerosa, Halymenia,
Porphyra, and Sargassum spp. are other seaweeds with
economic significance (BFAR, 2010).
Seaweeds are the top aquaculture species cultivated from
all regions (excluding National Capital Region and
Cordillera Administrative Region), with 1.48 million MT
comprising about 64% of the total production in 2018,
where BARMM (Bangsamoro Autonomous in Muslim
Mindanao) is a significant producer (BFAR, 2019; PSA,
2019). Philippines ranked 4th in seaweed production next
to China, Indonesia, and the Republic of Korea (FAO,
2020). Seaweeds are exported in both processed (semi-
refined chips/carrageenan and refined carrageenan) and
raw (fresh or dried seaweeds) forms. The Philippines
exported carrageenan in both semi-refined and refined
form, mainly to the USA, Mexico, Belgium, Thailand,
Denmark, Australia, Russia, Spain, France, and Brazil,
with about US$185 million in 2018. At the same time, the
major importing countries of the raw forms were Spain,
Argentina, China, the USA, and Brazil, with a value of
about US$16 million (BFAR, 2019).
Seaweed farming is the primary livelihood source
for coastal villagers, particularly in the BARMM, Southern
Philippines (BFAR, 2010; Romero, 2002). It is considered
a family venture involving nearly all family members,
including children (Romero, 2002). Seaweed farming
utilizes between 100 000-120 000 labors, where 90% are
seaweed farmers, and the rest are seaweed processors and
traders (BFAR, 2010). There are several culture methods
practiced in the country. These include fixed off-bottom or
bottom stake, bamboo raft, floating monoline, raft longline,
and hanging longline (Hurtado, 2003; Romero, 2002;
Sabdani, 2002). The harvesting period varies from region
to region, ranging from 20 to 60 days (Mundo et al., 2002;
Romero, 2002) or usually after 45 days (Samonte, 2017).
Philippine seaweed production in 2018 is shown in Table
5, where BARMM was the major seaweed-producing
region.
Milkfish: Milkfish (Chanos chanos) or locally
called Bangus, is considered the Philippines' official
national fish (Bagarinao, 1998). Farming of this fish
species has been carried out in Southeast Asia for over 50
decades and is now considered the most important farmed
fish (Sumagaysay-chavoso, 2003; Yap et al., 2007).
Milkfish is the 2nd aquaculture production species
comprising 13% of the total production (BFAR, 2019;
PSA, 2019). Milkfish is cultured in brackish water,
freshwater lakes, estuarine areas, and coastal marine waters
using various culture systems like ponds, cages, and pens
(Yap et al., 2007).

Tilapia: Before tilapia deemed as the second
popular cultivated fish in the Philippines, tilapia (mainly
the dark “Java” tilapia, Oreochromis mossambicus) was a
disliked fish: bothersome to consumers who favored
marine and brackish water species and disdained by
fishpond operators who perceived the fish as a pest. All of
that has changed with acknowledging that Nile tilapia (O.
niloticus) is a far prevalent species for cultivation (Smith
& Pullin, 1984). The six farmed tilapia species in the
country are Nile tilapia Oreochromis niloticus together
with its genetic strains, Mozambique tilapia (O.
mossambicus), Blue tilapia (O. aureus), and Redbelly
tilapia (Coptodon zilli), Blackchin tilapia (Sarotherodon
melanotheron), and Red tilapia (Oreochromis spp.
hybrids) (Guerrero, 1979; Romana-Eguia et al., 2020).
These tilapia species are all introduced species. The first
tilapia species introduced in the country from Thailand in
1950 was O. mossambicus. It was then followed by O.
niloticus in 1972 and other species (O. hornorum, O.
aureus, Coptodon zilli, and S. melanotheron) (Guerrero,
2019). Tilapias are considered so versatile in various
environments that it has been referred to as “aquatic
chicken” (Acosta & Gupta, 2010). Tilapias are typically
grown using semi-intensive or intensive culture techniques
under various cultivation and environmental factors,
stocking rates, and management approach (El-Sayed,
Tahiluddin & Terzi, (2021) J. Anatolian Env. and Anim. Sciences, Year:6, No:4, (475-486), 2021
479
2019). Romana-Eguia et al. (2020) detailed the basic
concepts of tilapia cultivation in the Philippines in various
farming techniques such as cage cultivation, pond
cultivation, monosex male tilapia cultivation, saltwater
cultivation, rice-fish (tilapia) cultivation, and aquaponics.
Shrimps/Prawns: Shrimps/Prawns are the 4th
important species cultivated in the Philippines, with 47 060
MT contributing about 2% of the total aquaculture
production in 2018 (BFAR, 2019; PSA, 2019). The main
cultured shrimp/prawn species in brackish water ponds are
Peneaus monodon, P. vannamei, P. indicus, P. setiferus,
and Metapenaeus ensis. Another species of prawn,
freshwater prawn Macrobrachium rosenbergii, is also
recently cultivated around 2001 (Rosario & Tayamen,
2007), but its production is negligible compared to the
above shrimp/prawn species (PSA, 2019).
Tiger prawn (Peneaus monodon) is an essential
export species cultured throughout the Philippines. This
species' cultivation was regarded as a minor species
harvested along with the milkfish. It became the
predominant species in 1951 propagated in brackish water
pond in which the source of seed stocks came from the
wild. In the 1980s, when SEAFDEC promoted the hatchery
technology, farming of this species became successful and
commercially practiced nationwide (Rosario & Lopez,
2005).
Culture System
The culture system varies according to species as
well as environments. In the Philippines, fishpond, fish
cage, fish pen, and mariculture are the major culture
systems practiced in brackish water, freshwater, and
marine environments. In 2018, mariculture had the highest
production (nearly 1.5 million MT), where seaweeds,
oysters, and mussels were the primary cultured species.
Almost 0.5 million MT was produced from the fishpond in
freshwater and brackish water environment. The fish cage
production was about 0.2 million MT, while fish pen
production was about 70 000 MT produced from the fish
pen in all environments. Farm reservoir and rice-fish
productions were 83 and 3 MT, respectively (BFAR, 2019)
(Table 6).
In brackish water, the most popular cultured fish
are milkfish, tilapia, grouper, siganid, and crustaceans such
as tiger prawn, white shrimp, endeavor prawn, and mud
crab. In the freshwater environment, major cultured species
are milkfish, carp, catfish, mudfish, gourami, and
freshwater prawn. In the marine environment, species with
high production mostly come from seaweeds, oysters,
mussels, milkfish, grouper, siganid, mud crab, spiny
lobster, and tiger prawn. Farming of fish in the rice field
and farm reservoir is also done of which tilapia, carp,
catfish, mudfish, and gourami are the species cultivated
(BFAR, 2019).

Marine Fisheries
Marine fisheries are defined as the extraction of
wild living resources in coastal and open sea for human
sustenance or markets. Marine Fisheries resources include
various fishes as well as invertebrates like mollusks,
crustaceans, and sea cucumbers. In the Philippines, marine
fisheries is composed of two sectors, municipal fisheries or
small-scale fisheries and commercial fisheries or large-
scale fisheries (Luna et al., 2004). Marine fisheries are a
significant protein source, sustenance, and export earning
of the Philippines (Barut et al., 1997).
From municipal and commercial sectors, marine
fisheries constituted about 47% or approximately 2 million
MT of Philippine production in 2018 (BFAR, 2019). In the
Philippines, the most productive fishing grounds are the
West Palawan Sea, South Sulu Sea, Visayan Sea, Moro
Gulf, and Bohol Sea (BFAR, 2000). The most common
types of fishing gears used in the Philippines are drift
gillnet, purse seine, bag net, ring net, trawl, beach seine,
Danish seine, handline, multiple handline, longline, and
bottom set longline (Santos et al., 2017).
Municipal Fisheries
Municipal fisheries is marine fisheries where
fishing is carried out along coastal and inland waters with
or without the use of vessels of 3 gross tons or less (BFAR,
2019).
Municipal production: In 2018, the municipal
production both from marine and inland waters was mainly
contributed by Region IX-B, Region V, BARMM, Region
IX, and Region VI, as shown in Table 7. Production from
marine waters was about 942 000 MT, primarily composed
of big-eyed scad, Indian sardines, frigate tuna, round scad,
fimbriated sardines, slipmouth, squid, Indian mackerel,
yellowfin tuna, and anchovies (Table 8). On the other hand,
production from inland waters was about 164 000 MT,
mainly comprising tilapia, carp, mudfish, freshwater
catfish, milkfish, gourami, freshwater shrimp, big-head
carp, freshwater goby, silver perch, mullet, and freshwater
sardines (Table 9) (BFAR, 2019).

Municipal fishing vessels: The total number of
municipal fishing vessels in the country was about 259 000,
dominated mainly by regions VIII, VI, VII, IV-B, and
BARMM (Table 10) (BFAR, 2019).
Municipal fishing gears: The municipal fisheries
in Lingayen Gulf mostly used line gears like handline,
multiple handline, bottom longline, spear guns, push net,
and fish trap/pot (Gaerlan et al., 2018). The fishing gears
used in the Scarborough Shoal mainly comprised of
variations of gillnets (bottom-set, drift, and ring nets) and
hook-and-line (drift, multiple, and simple handlines), as
well as speargun and jig of which the catch was dominated
mainly by Acanthuridae, Balistidae, Lethrinidae, and
Scombridae (Arceo et al., 2020).

Commercial Fisheries
The Philippine Fisheries Code of 1998 defines
commercial fishing as taking fishery species by passive or
active fishing gears for trade, business, or profit beyond
subsistence or sports fishing. Fishing is done using vessels
of more than 3 gross tons (BFAR, 2019; Luna et al., 2004).
Commercial production: In 2018, commercial
production was about 946 000 MT. The major fish species
were primarily represented by skipjack, Indian sardines,
yellowfin tuna, frigate tuna, fimbriated sardines, big-eyed
scad, eastern little tuna, Indian mackerel, slipmouth, and
indo-pacific mackerel (BFAR, 2019.)
Tunas, family Scombridae, are being fished
throughout the country’s waters. A recent study by
Nepomuceno et al. (2020) emphasized that Philippine
waters, particularly the West Philippine Sea and Batanes-
Polillo waters, have the most bountiful tuna species in
species diversity.

Tunas are the top export commodities of the
Philippines. In 2018, 39% (approximately 430 000 MT) of
the commercial production was composed of tuna species
like skipjack (K. pelamis), yellowfin tuna (T. albacares),
frigate tuna (A. thazard), and eastern little tuna (E. affinis).
About 170 000 MT of tuna products, both fresh and
preserved, amounting to roughly US$500 million, was
exported to the UK, Japan, Germany, Spain, the USA,
Netherlands, Italy, Poland, Israel, Portugal, Cyprus,
Indonesia, Switzerland, and other countries (BFAR, 2019).
Commercial fishing vessels: Commercial fishing
vessels in the Philippines had more than 8 000, with more
than 3 000 fishing operators. The NCR had the highest total
number of commercial fishing vessel operators (2 362)
with 6 422 commercial fishing vessels in 2018 (Table 12)
(BFAR, 2019).
Commercial fishing gears: Commercial fishing
gears operate across the country’s waters are Danish seine,
purse seine, trawls (commercial trawl, pair trawl, and
midwater trawl), ring net, drift filter net, bag net, handline,
multiple hook and line, and troll line (Santos et al., 2017).

CHALLENGES IN THE PHILIPPINE
FISHERIES AND AQUACULTURE
Challenges in the Philippine Aquaculture
The aquaculture sector in the Philippines faces
many challenges despite large volume of production in
recent consecutive years. The most common challenges are
pests and diseases, water quality degradation, the
occurrence of harmful algal blooms, and lack of capital and
government support.
Pests and Diseases: Significant losses in seaweed
production have been attributed mainly to pests and
diseases (Ward et al. 2020; Faisan et al. 2021). The most
common pests and diseases affecting seaweed farms in the
country are ice-ice disease and epiphytic filamentous algae
(Faisan et al. 2021). Ice-ice disease is generally caused by
biotic (pathogenic bacteria and marine-derived fungi) and
abiotic (light, temperature, salinity, nutrients) factors,
where the infected branches of the seaweeds appeared as
white and soft, which can disintegrate easily, resulting in
losses in the farms thereby causing a severe production
Tahiluddin & Terzi, (2021) J. Anatolian Env. and Anim. Sciences, Year:6, No:4, (475-486), 2021
482
decline (Largo et al., 1995a; Largo et al., 1995b; Mendoza
et al., 2002; Solis et al. 2010; Tahiluddin and Terzi, 2021).
Another problem in seaweed farming is the epiphytic
filamentous algae. These pests, which are prevalent in the
country, are attached using their holdfast in the host plants;
and the infected branches of the seaweeds show epiphytes
penetrating the cortex and growing within the medullary
(Faisan et al., 2021). Epiphytic filamentous algae are also
responsible for a significant decline in carrageenan quality
and production biomass of farmed Kappaphycus and
Eucheuma species (Ward et al. 2020).
Tilapias are also affected by diseases, especially
bacterial and viral diseases, despite being a nearly hardy
fish. The most commonly reported bacterial diseases are
streptococcosis, motile Aeromonas septicemia, and
Pseudomonas infections (Duremdez and Lio-Po, 1988;
Yambot, 1998; Reyes et al., 2019; Limbauan, 2018;
Legario et al., 2020). In addition, Tilapia Lake Virus, a
viral disease that emerged recently, threatens tilapia
aquaculture in the country as well as worldwide (Aich et
al., 2021; OIE, 2017).
Disease outbreaks in shrimp aquaculture have
resulted in substantial production decline over the last
decades, which has become more challenging for the
country to claim back the title as the global shrimp leader.
Shrimp diseases can be viral, bacterial, and protozoan.
Among the most common diseases which have significant
impacts are white spot disease (WSD), white feces disease
(WFD), early mortality syndrome (EMS),
hepatopancreatic microsporidiosis (HPM), luminous
vibriosis, filamentous bacterial disease, shell disease,
ciliate Infestation, black gill disease, and chronic soft-shell
syndrome (Hays, 2020).
Water quality degradation: Water quality
degradation in ecosystems that support aquaculture is still
a main issue in the Philippines, especially in Luzon. For
example, in Taal Lake, concentrations of phosphates,
nitrates, and total dissolved solids were significantly higher
in aquaculture cage sites than in areas without aquaculture
activities (Querijero & Mercurio, 2016; Cruz et al., 2019).
Furthermore, the current status of Manila Bay revealed that
the levels of PO4 -3 (1.02 mg/L 2.42 mg/L) and NH3-N
(0.90 mg/L 2.35 mg/L) were unsuitable for fish culture,
although other important parameters like temperature,
dissolved oxygen, pH, etc. were within the safe levels
(Baldoza et al., 2020). Moreover, high water temperature
(>32 °C) was the major challenge that has a significant
impact on tilapia aquaculture, particularly in Luzon and
Mindanao (Guerrero, 2019).
Harmful algal blooms (HABs): Harmful Algal
blooms (HABs) have been a country's problem for the last
decades affecting the aquatic environment, aquaculture
sites, infected farmed species, country’s economy, and
even a human’s life. For instance, in Laguna de Bay, due
to human activity such as disposal of nutrients (nitrate and
phosphate), under favorable environmental conditions,
algal blooms can be expected degrading water quality like
low oxygen and toxin production. This is the main cause of
fish kill in most Luzon in recent years (De Vera-Ruiz,
2021). HABs occurrence also has a great impact on the
national economy of the country as well as threatening
public health. For example, from 1983 to 2002, there were
2122 cases of paralytic shellfish poisoning with 117 deaths.
Moreover, in the same year duration, HABs resulted in; a)
economic losses and damages amounting to 2.2 million
pesos, b) extensive economic damages, c) problem in the
international trades, d) unemployment of many shellfish
industries, and e) displacement and losses of livelihood for
thousands of fishers (BFAR, 2021).
Lack of capital and government support:
Farming of seaweeds is usually dependent on the
availability of capital (funds) in order to start farming
(Romero, 2002). In Tawi-Tawi, Southern Philippines, one
of the problems that hindered farmers from intensifying
seaweed farming was the lack of capital and government
support, which resulted in low socio-economic status
(Tahiluddin and Delasas, unpublished). In tilapia
aquaculture, lack of capital and government support has
been identified as one of the prime causes of low tilapia
production (Guerrero, 2019).
Challenges in Philippine Marine Fisheries
Overfishing, destructive and illegal fishing, and
weak law enforcement are among the prevalent challenges
in marine fisheries in the Philippines.
Overfishing: Overfishing in the Philippines has
been observed in the 1990s and may have been started in
the 1980s (Israel & Banzon, 1997; Camacho, 1999). In the
20th century, small pelagic fishes in the country were
overfished (Dalzell & Ganaden, 1987), and recently some
fisheries officials blamed overfishing in Samar and Bicol
for rotting sardines in Bulan, Sorsogon province (Toledo,
2021). Also, sea cucumbers in some provinces are
overexploited, evident from previous studies (Olavides et
al., 2010; Jontila et al., 2017; Ajik et al., 2021), although
the Philippines remains as the second major sea cucumber-
producing country in Southeast Asia (Alejandro, 2019).
According to the chief of the Fish Right Program in the
Philippines of the United States Agency for International
Development (USAid), 70% of fishing grounds in the
country are currently overfished (Aguirre, 2019).
Destructive and illegal fishing: Dynamite (blast)
fishing, cyanide fishing, and using destructive fishing gears
are considered damaging to habitats and aquatic resources
(Camacho, 1999; Erdmann et al., 2000). In addition,
Philippine coral reefs have been damaged by the use of
Tahiluddin & Terzi, (2021) J. Anatolian Env. and Anim. Sciences, Year:6, No:4, (475-486), 2021
483
destructive fishing methods (Alcala & Russ, 2002). Even
in this pandemic, illegal fishing was reported to spike
during the lockdown from March to May 2020 (Espenilla,
2020). In 2019, illegal fishing from municipal and
commercial fisheries comprised 27-40% of the total
production amounting to 42-63 billion pesos (BFAR,
2020). In addition, unreported, unregulated, and
unregistered fishing are also significant challenges in the
marine fisheries sector of the country (BFAR, 2020).
Weak law enforcement: Weak law enforcement
has resulted in the rampant use of destructive and illegal
fishing in the country, leading to overfishing. For example,
in Calamianes Island, Palawan, weak law enforcement
prevails, and local fishers are even accused of corruption
in fisheries governance, such as a strong link between the
law enforcement agent and unscrupulous operators/traders
(Fabinyi, 2007).
RESPONSE TO THE CHALLENGES AND
RECOMMENDATION
The challenges mentioned above have been a long
hindrance to the sustainability of Philippine fisheries and
aquaculture. Pests and diseases in aquaculture, particularly
in seaweed farming, must be given attention in future
research like looking and further understanding the water
parameters of the farm as well as the role of pathogenic
microorganisms. Our previous paper (Tahiluddin and
Terzi, 2021) reviewed the causes, occurrence, and some
control measures of ice-ice disease of Kappaphycus and
Eucheuma species may be beneficial to minimize this
disease and can be used to further investigate for proper
disease management. In general, biosecurity measures and
aquatic disease surveillance must be imposed and
enhanced to reduce pests and diseases in aquaculture. In
addition, future researches may also focus on investigating
the potential environmental-friendly and efficient ways of
reducing, eliminating, or treating pests and diseases in
aquaculture.
To monitor and maintain water quality, there
should be a regular assessment or future researches of
water quality, especially in aquaculture sites nationwide. In
order to attain water quality standards, strict compliance
with the Code of Good Aquaculture Practices must be
imposed (Baldoza et al., 2020).
Although HABs monitoring in the Philippines is
regularly monitored by the Bureau of Fisheries and Aquatic
Resources (BFAR), especially in the area where laboratory
equipment is available, coverage areas should be expanded
to cover more areas where shellfish farming is being
practiced and monitoring and surveillance should be
improved. The development of a rapid test for detecting
HABs would also be helpful for fast detection, early
warnings, and avoidance of great losses both HABs-
infested species as well as consumers’ life. Likewise,
researchers must consider and explore HABs through
extensive research in many parts of the country.
The government must prioritize farmers and
fishers in giving and providing assistance/support to
improve the country’s fisheries and aquaculture sectors.
Overfishing, destructive and illegal fishing are all liked to
weak enforcement of existing laws pertaining to proper
utilization and management of Philippine fisheries
resources. Hence, to boost fish production, there is a need
for stronger enforcement measures to attain seafood self-
sufficiency and sustainable fisheries in the country.
CONCLUSION
Philippine fisheries comprise three sectors;
aquaculture, municipal fisheries, and commercial fisheries.
Aquaculture consistently maintained high production for
consecutive 5 years from 2014 to 2018, around 2.2 to 2.3
million MT, mainly from the mariculture of seaweeds,
fishpond, and the fish cage of milkfish and tilapia.
Municipal fisheries contributed nearly 1.1 to 1.2 million
MT in the same years, primarily from big-eyed scad, Indian
sardines, and frigate tuna. From about 1.1 million MT in
2014 to about 950 000 MT, commercial fisheries
production gradually decreased, which may be due to
overexploitation. Skipjack, Indian sardines, and yellowfin
tuna are the major species from the commercial sector. The
fisheries sector provides both foreign exchange and
employment to the country despite the existing challenges.

... The Philippine archipelago, a unique and diverse ecosystem, is a haven for marine biodiversity. With 7641 islands and 2 200 000 km 2 of total territorial water, including an exclusive economic zone (EEZ) (BFAR, 2019;Tahiluddin and Terzi, 2021), it is the original home of tropical seagrasses (Carpenter and Springer, 2005;Malanguis et al., 2024). Seagrasses, highly specialized flowering plants in temperate and tropical locations, thrive in brackish and marine waters, serving as crucial marine habitats and nursery areas for commercially important marine organisms (Fortes, 2012;Jumawan et al., 2015). ...

Seagrass plays a vital role in coastal ecosystems by supporting biodiversity, fisheries, and local economies. However, security concerns have limited research on seagrass in Sulu and Basilan, Philippines. This study assessed the seagrass status across 12 coastal municipalities in the provinces of Sulu and Basilan, Philippines, using the line transect-quadrat method, covering 580 transects and 5,600 plots. Six seagrass species from the family Cymodoceaceae (Cymodocea rotundata, Halodule uninervis and Syringodium isoetifolium) and the family Hydrocharitaceae (Enhalus acoroides, Halophila ovalis and Thalassia hemprichii) were identified. Seagrass cover was fair in Omar (41.83%), Pangutaran (33.18%), Tabuan Lasa (31.96%), Luuk (29.73%), and Banguingui (28.89%), while it was poor in Sumisip (21.75%), Hadji Muhtamad (18.78%), Hadji Panglima Tahil (18.43%), Patikul (15.98%), Lantawan (15.10%), Maluso (14.25%) and Panamao (9.60%). T. hemprichii (45.97%) and C. rotundata (35.44%) dominated, collectively comprising 81% of the total cover. E. acoroides contributed 18.76%, while the remaining species had low coverage (7.85%–11.74%). Diversity indices indicated low diversity with an overall Shannon-Weiner diversity index (H = 1.3367), Pielou’s evenness (e = 0.13566), and Margalef’s index (Sm = 0.4807). Associated flora included Chlorophyta, Rhodophyta, and Phaeophyta, while fauna was dominated by Asteroidea, Anthozoa, Gastropoda, and Echinodea. Thus, the degraded seagrass beds in the eastern part of the Sulu Sea highlight the need for immediate conservation efforts, monitoring, and management strategies. Protecting these habitats is crucial for biodiversity and sustaining local livelihoods dependent on the Sulu Sea’s resources.

The Philippines is the second biggest source of skipjack tuna (Katsuwonus pelamis), contributing to the country’s economic development. However, its sustainability faces challenges due to overfishing and a lack of proper management practices. Otoliths are important tools for managing fish stocks, but their analysis is time-consuming and requires a high level of expertise. In this paper, we explored the use of convolutional neural networks (CNNs) to recognize patterns and classify them according to developmental stages. The results showed that the CNN model achieved an accuracy of 100% in classifying otoliths by developmental stage using the RMSprop optimizer, demonstrating the potential of deep learning to provide a standardized and reliable protocol for managing fish stocks in countries like the Philippines, where there is a shortage of trained fish experts. This study provides an innovative approach to guide future efforts in conserving fish populations and promoting sustainable fishing practices.
... Seaweeds, primarily eucheumatoids such as Kappaphycus alvarezii, K. striatus, and Eucheuma denticulatum, are the leading aquaculture species cultivated in the Philippines (Tahiluddin and Terzi 2021a). Data from the Philippine Statistics Authority (PSA) indicate that seaweed production in the Philippines remained relatively stable at around 1.6 million metric tons between 2013 and 2015. ...
Chapter
Tawi-Tawi province in the southern Philippines holds a significant place in the history of eucheumatoid seaweed farming. In 1969, it established the world’s first commercially successful eucheumatoid seaweed farm. Today, Tawi-Tawi remains the leading producer of raw dried seaweeds (RDS) in the country for the global carrageenan industry. This family-oriented enterprise is a critical source of livelihood for coastal and marginalized communities. The primary cultivated species are Kappaphycus alvarezii and K. striatus. Modified fixed off-bottom and floating methods are the dominant cultivation techniques employed in the region. However, seaweed farmers in Tawi-Tawi are confronted with several challenges that hinder RDS production. These problems include pests, diseases, seasonal slow growth, grazers, constrained expansion of farming area, and lack of capital. Additionally, price fluctuations of RDS also pose a significant and uncontrollable dilemma that dissuades some farmers from intensifying farming activities. This contributes to cases of farmers abandoning seaweed farming livelihood due to other compounding predicaments. To address these challenges, farmers are adopting good aquaculture practices in controlling pest infestation but have resorted to using inorganic nutrient enrichment to increase biomass production, reduce crop period, and purportedly improve plant vigor against ice-ice disease contagion. Recommendations for improving and sustaining eucheumatoid seaweed production in the province are provided in this chapter.
... However, not all of these are considered sustainable by Fisher folks. Gear used in hook and line, pamana, lambat, pukot, kubkuban, and sahid are the same gears used by Fisher folks in the municipalities of Lingayen Gulf and Scarborough Shoal (Gaerlan, et al., 2018;Arceo, et al., 2020;Tahiluddin and Terzi, 2021). Whereas, fisher folks in the province of Zamboanga believe that hook and line is the most sustainable fishing method (Schijvenaars, 2017). ...

The European Union (EU) recognized that there is rampant illegal, unreported, and unregulated (IUU) fishing in the Philippines, resulting to a noticeable decline in fish population. To retrace sustainable fishing practices, this research sought to illustrate the fishing methods that fisher folks employ and narrate their experiences during their fishing activities. This research employed a multiple case study approach. To fully understand the experiences of the fisher folks in their fishing activities, one-on-one in depth semi-structured interviews have been conducted as well as scheduled visits in order to gather data. The collected data underwent a narrative analysis. The study was conducted in three fishing communities of Antique, specifically; Hamtic, Tibiao, and San Jose. In order to identify participants of the study, purposive sampling was used as the participants must meet certain criteria. The participants were registered fisher folks and members of a fisher folk organization registered in the barangays. Furthermore, they have been in the fishing industry for ten (10) years or more. Result of the study revealed that 1. Fisher folks indeed observe regulated and legal fishing methods; 2. Despite the observance of sustainable fishing methods there is still a noticeable decline in fish population; 3. The presence of kubkuban near municipal territories has been cited as a potential cause for overfishing, and 4. Weak law enforcement in the Philippine seas allow rampant illegal, unreported, and unregulated (IUU) fishing to persist. The findings suggest that fisher folks show resiliency in their choice of fishing methods as they are more conservative in managing marine resources. However, government must review and monitor the effects of kubkuban on the sustainable development of marine resources and review the Philippine fisheries code. Furthermore, there is a need to strengthen law enforcement in the Philippine seas.

Fish processing occurs internationally through both traditional and non-traditional methods. In the Philippines, traditional techniques are rooted in a long nutritional culture, while modern methods are gaining popularity. Fish and fishery products are vital for nutrition and food security, but overfishing and post-harvest loss pose challenges. Drying is a common method, transitioning from sun drying to cabinet-style dehydrators. Quality relies on proper drying conditions and raw material quality. Factors like pesticide use, drying temperature, cleanliness, and storage affect quality. The texture, color, and microbiological aspects of a product are influenced by gutting, salting, and diverse drying methods. Additionally, the use of both natural and synthetic additives, along with antioxidants, plays a crucial role in preserving the quality of the product. Nutritional and sensory characteristics are influenced by fish species, environment, and drying methods. Understanding these dynamics is essential for maintaining fish quality and nutrition during processing.

The growth and survival of Penaeus monodon and other commercial species and the production performance of Integrated Multitrophic Aquaculture (IMTA) system were evaluated in a 500 m2 experimental grow-out ponds of Mindanao State University at Naawan for 120 days. Three triplicated treatments, monoculture (P. monodon only), polyculture (P. monodon and Chanos chanos) and IMTA (P. monodon, C. chanos, Perna viridis and Gracilaria verrucosa) were evaluated in a semi-intensive pond culture operation. Salinity (24.3 to 34.36‰), temperature (28 to 40.64°C) and pH (7.5 to 9.49) exceeded the maximum ideal limit for the cultured organisms in all treatments. Dissolved oxygen levels (2.76-5.43) were within the optimal range of some cultured organisms. Growth of shrimp (5.33±0.02 %SGR P <0.05) and milkfish (4.49±0.03 %SGR P <0.05) were significantly better in IMTA than in polyculture. Shrimp’s survival was also significantly higher in IMTA (24.13%±3.95, P <0.05) than in the other treatments. Shrimp-milkfish biomass was highest in IMTA (89.67 kg), followed by polyculture (57.72 kg) and lowest in monoculture (11.33 kg). The higher biomass and survival of shrimp and milkfish in IMTA ponds could be attributed to the cultured organisms' synergistic interaction, such as shading and nutrient remediation by G. verrucosa and bioremediation by P. viridis. Revenue and profit followed a similar trend, with IMTA revealing profitability over the polyculture and monoculture. Hence, the results demonstrate the efficiency of the IMTA systems over monoculture and polyculture in the growth and survival of the high-valued jumbo tiger shrimp, P. monodon and the overall production and profitability.

The cultivation of aquatic species faces a significant challenge due to water quality degradation, which impacts farming operations and poses a threat to livelihoods. To contribute to advancing aquaculture informatics and enabling more precise and convenient monitoring of aquaculture ponds, this study introduces an IoT-based Water Quality Monitoring System for Fishponds. This system is designed to measure pH and salinity values in real-time, aiming to address the pressing need for continuous monitoring and management of water quality parameters for cultivating milkfish (Chanos chanos). Users can remotely access and control measurements by integrating the prototype with the Blynk IoT system, ensuring that water quality remains within optimal thresholds or 6.5 to 8.5 pH for acidity and 18 to 29 ppt for salinity. In addition, the system is equipped with an alert system to notify end-users when the parameters exceed predetermined limits promptly. The prototype received an average functionality score of 4.325 and an efficiency score of 4.13. The error percentages recorded were 0.027% for acidity, 0.187% for salinity, and 4.36% for overall effectiveness. This system enhances cultivation security, enabling farmers to make informed decisions and take timely actions to maintain optimal water quality conditions in fishponds.

The Philippines is renowned for its emerging aquaculture industry in both freshwater and marine environments, as well as its significant research on microplastics (MPs). However, there is a lack of information and sources on MPs in different regions. This study investigated the presence of MPs in aquaculture systems (fishponds and marine cages) in Baler, Aurora. The microplastics isolated were characterized in terms of type, shape, color and polymer type. Samples of water, sediments, and fish all contained microplastics. A higher concentration of MPs was observed in marine cages compared to freshwater fishponds, with a total average concentration of 69.5 items mL-1 (water), 51.67 items g-1 (sediments), and 168 items pc-1 (fish). Using a stereomicroscope, MPs were characterized based on the types, shapes, and colors found in the water, sediments, and fish samples. The study revealed different types of MP at varying frequencies, with fibers and fragments being the most common. In marine cages, the concentration of fibers was significantly higher, with a frequency of 63.22 items pc-1 in marine fish (milkfish) and 12.2 items mL-1 in water. In freshwater fishponds, the concentration of fragments was higher, with a frequency of 35.44 items pc-1 in fish (tilapia) and 7.6 items mL-1 in water. The highest frequency of MPs in sediments was found in fragments, with 9.28 items g-1 observed in freshwater fishponds. The most common shape of MPs was irregular, with white and black colors in both systems, especially in fish. Fourier transform infrared spectrometer analysis identified polymers such as rayon, polyethylene, and polypropylene in freshwater ponds and polypropylene and nylon in marine cages. Despite variations in MP types and shapes, independent t-tests indicate no significant difference in MP concentrations between the two aquaculture environments. This study emphasizes the widespread nature of MP pollution and suggests the need for effective mitigation strategies for responsible aquaculture practices.

Eucheumatoid seaweed farmers face a confluence of challenges emanating from presumed nutrient deficiency due to over-cropping, leading to low yields and frequent ice-ice disease outbreaks. Despite limited data on systemic nutrient limitations, some farmers clandestinely apply commercial inorganic fertilizers to accelerate growth and harvest premature crops after half of the prescribed 45-day cultivation period, sparking controversy. Unlike terrestrial agriculture, the use of inorganic fertilizers in eucheumatoid seaweed farming (ESF) is contentious. This stems from the haphazard use of the term “organic” to classify sea-grown crops without using synthetic fertilizers. However, when anthropogenic inorganic nutrient pollution fertilizes coastal seas, this effectively disqualifies these crops from the “organic” produce classification. This paper critically explores the use of artificial nutrient enrichment in ESF, assessing its impact on the crop's growth, ice-ice disease mitigation, carrageenan quality, and the marine environment. While controlled fundamental studies have shown that nutrient enrichment can significantly increase growth and potentially reduce disease occurrence, its inconsistent positive and negative effects on carrageenan yield and quality require further investigation with emphasis on organismal nutrient physiology and metabolism. Inorganic nutrient enrichment could also potentially alter the microbiome of eucheumatoid seaweeds. Whether inorganic nutrient enrichment in ESF will be sanctioned by the local and global regulators and policy makers, or not, increased knowledge is crucial for establishing basic science in order to rationally discuss challenges contributing to the decreasing production of quality raw, dried, eucheumatoid seaweed biomass for carrageenan processing, without compromising environmental and social responsibilities. Currently, the routine use of inorganic fertilizers in ESF is not authorized and remains a very sensitive issue, especially among marginalized subsistence seaweed farmers. In conclusion, inorganic nutrient enrichment in ESF presents a double-edged sword: whilst it can boost growth and potentially combat disease, its practice raises concerns on carrageenan yield and quality, and environmental pollution, as well as regulatory organic codes, necessitating further research for responsible implementation, when sanctioned. The bottom line is that when prescribed by regulators, the raw dried seaweed (RDS) and the subsequent products (both semirefined and refined carrageenans) cannot be certified as “organic” when the crop is cultivated using inorganic fertilizers.

Kappaphycus spp. and Eucheuma spp. are two economically significant seaweed species cultivated globally due to their carrageenan content with numerous commercial applications. They are mainly cultivated in the Philippines, Indonesia, Malaysia, and Tanzania. The culture of these seaweeds also provides income sources for many coastal dwellers. In 2018, the total global production from these seaweeds was about 11 million tonnes. One of the primary problems that affect seaweed production is the incidence of ice-ice disease. In this article, we reviewed the reported scientific journals on the ice-ice disease of two commercially cultured seaweed species (Kappaphycus spp. and Eucheuma spp.), focusing mainly on causes, occurrence, and control measures. The ice-ice disease is caused by both abiotic and biotic factors manifested by the presence of white and soft parts in the infected seaweeds. The occurrence of this disease varies from species, places, and seasons. Control measures may include proper farm management, polyculture with other seaweeds, pre-soaking with antibacterial substances and nutrient enrichment before out-planting, and possibly using genetic engineering.

This study determined the effect of different concentrations of ammonium phosphate on the yield and quality (gel strength, viscosity, syneresis, gelling, and melting temperature) of carrageenan. The study was conducted at the Seaweeds Post-Harvest Laboratory, College of Fisheries, Mindanao State University for 33 days. The experiment involved four treatments and three replications. The four treatments were the different concentrations of ammonium phosphate (g/L) namely; Treatment 1 (T1)-0g/L, Treatment 2 (T2)-3 g/L, Treatment 3 (T3)-6 g/L, Treatment 4 (T4)-9 g/L. The results showed that the application of ammonium phosphate significantly reduced the yield and viscosity of the carrageenan by 4.81% and 1.83cPs respectively. Gel strength was enhanced by 1.53g in T2 (3/L). Control showed the best syneresis compared to the other treatment. The syneresis was significantly decreased by 5.43% with the application of ammonium phosphate. The fertilizer seemed not to have any effect on the gelling and melting temperature of the carrageenan. Ammonium phosphate is therefore not recommended for growing Kappaphycus striatus for carrageenan.

Streptococcosis cause severe losses for global tilapia farming, especially in developing countries. The aim of this study was to identify and characterize streptococci recovered from Nile tilapia farmed in the Philippines. Moribund and apparently healthy fish were sampled from grow-out cages, ponds and hatcheries. Clinical signs observed included exophthalmia, eye opacity, ascites, lethargy, erratic swimming and haemorrhages. Results showed that both Streptococcus iniae and Streptococcus agalactiae were associated with disease in these sites. Consistent with global reports, including those from South-East Asia, S. agalactiae was more widespread than S. iniae. Molecular serotyping of the S. agalactiae isolates identified the serotype Ia and serotype Ib. Histopathological findings were meningitis, meningoencephalitis and septicaemia. Identical virulence profiles were found for all strains of S. iniae, while S. agalactiae strains were separated into virulence profile I and profile II. All strains were susceptible to the tested antibiotics and resistant to oxolinic acid. Only S. agalactiae serotype Ib showed resistance to sulphamethoxazole-trimethoprim. This is the first study from the Philippines to characterize the streptococci involved in disease outbreaks in tilapia aquaculture. Outputs from this study will promote the development of efficacious disease control strategies in tilapia farming for the Philippines and South-East Asia.

The Philippines is a significant producer of tunas globally but has experienced a decline in tuna production in recent years. Thus, efforts to explore and assess new fishing grounds were conducted by the Bureau of Fisheries and Aquatic Resources (BFAR) through M/V DA-BFAR. Assessment of the spawning and nursery grounds of tunas in the country’s EEZ was also undertaken to properly manage and conserve tuna stocks. The said assessment commenced in 2006 and is continuing up to the present. All the data from 2006-2018 were compiled, including the data from collaborative studies with the University of the Philippines-Marine Science Institute and Southeast Asian Fisheries Development Center to create an overall profile of Scombridae’s abundance and distribution larvae in Philippine waters. The study results showed that family Scombridae is most abundant in the Philippine waters along Batanes-Polillo and areas off Eastern Luzon. Species diversity in Philippine waters was considerably high, with about six to eight dominant species. The most dominant species was Thunnus albacares., followed by Thunnus obesus, Auxis spp., Katsuwonus pelamis, unidentified Scombrid larvae, Rastrelliger spp., Thunnus alalunga, and Thunnus tonggol. The Scombridae species are diverse in the West Philippine Sea and Batanes-Polillo waters but not in Davao Oriental-Surigao waters.

Lake Taal is a source of livelihood and provides for more than 2,000 sustenance fisherfolk. Fish production of the open water fisheries has dwindled over the years with the continuous decline of fish catch, which can be attributed to unsustainable fishing practices such as illegal fishing, overfishing, pollution, and the expansion of aquaculture activities in the lake. Women, as a sector, constitute almost one half of the economically active population in Lake Taal. Men and women performed different roles at different stages of fish capture or fish culture. In terms of their economic and social value, the participation of women in pre- and post-production activities are significant. This study assessed the level of gender participation in the fisheries sector of Lake Taal. Specifically, it determined the roles of men and women in the different fishing activities and described the fisherfolk’s socioeconomic profile. A total of 407 randomly selected respondents were interviewed in 11 barangays from eight municipalities in Lake Taal, represented by 54% male and 46% female, consisting of 214 fishers, 76 fish vendors, four processors, 51 helpers, and 62 fish cage or fish pond owners, managers, and caretakers. Profiling of the socioeconomic status was done to assess families’ living conditions and constructed primary data based on household’s present roles, activities, responsibilities, access to and control over resources, problems, and constraints of men and women. The roles of both men and women in fisheries were categorized into three sectors: capture, post-harvest, and aquaculture.

Farmed eucheumatoids are the top aquaculture commodity in the Philippines, contributing more than 60% of total national aquaculture production by volume. Despite significant production losses observed in recent years due to pests and diseases, data relating to the temporal and spatial geographic distribution, seasonality, prevalence, and etiology of these critical problems at the farm level are lacking. Here, we assessed the prevalence of pests and diseases at 16 farm sites within several major seaweed growing areas, including Luzon (Palawan), Visayas (Bohol), and Mindanao (Zamboanga City, Davao del Norte, and Tawi-Tawi). Prevalence of pests and diseases were recorded by assessment of individual seaweed plants in situ, comprising ≥5% of the total number of seaweed plants on each farm. Results from this survey revealed “ice-ice” disease (IID) at all sites, albeit at low prevalence rates of below 25%, the exception being one site where prevalence was 100%. No significant difference in the prevalence of IID was found between farms in shallow (≈0.5 m during low tide) and deep water sites (depths exceeding 4 m during the lowest tide) (p>0.05). Moderate prevalence (26–50%) of the macro-epiphyte pests Sargassum and Ulva was reported in Luzon. Further, epiphytic filamentous algae (EFA), black spots, and evidence of grazing were recorded in several farms with low prevalence (0.2–11.2%). The three farms with the highest prevalence of IID and EFA were evaluated to determine the severity of cover on the thallus of infected plants. A very high severity of IID (76–100% coverage) was observed on the secondary and primary branches, while for EFA, low severity (≤25%) was found in all regions of the thallus. Our results suggest the widespread occurrence of yield-limiting diseases and pests affecting eucheumatoid farms in the Philippines. Strategies for the diagnosis, surveillance, and management of yield-limiting pests and diseases are needed to ensure maintenance and sustainable expansion of this important aquaculture sector in the Philippines.
