... In addition, integrated aquaculture involves reutilization of resources in addition to having a low space requirement. The most common form of integrated aquaculture system practiced is livestock-fish farming where animals like chicken, pig and duck have been used to produce manure that is used to fertilize ponds with the aim of improving both primary productivity and zooplankton proliferation [5]. Taken together, these core practices of integrated aquaculture augment agricultural productivity in ways that lower the magnitude of threat to biodiversity compared to non-integrated aquaculture [6,7]. ...
... Although a large number of farmers use agrochemicals such as inorganic fertilizers apparently because such chemicals are assumed to improve productivity [2,5], differences in productivity as a function of fertilization types remain largely unknown. However, many farmers still use these inorganic fertilizers that are known to be associated with pollution, yet the use of such chemicals may imperil not only fish but also other species including plankton, the key primary producers in aquatic ecosystems [8,9]. ...
... The species, C. gariepinus, is a generalist omnivore that is known to feed on natural foods in both its natural and captive environments [10]. African catfish are of great importance as they grow quickly, attain a large size with more flesh and few spines and are also able to withstand a wide range of environmental conditions, thus increasing this taxon's potential to contribute to food security [5]. Given its potential, the species is an excellent candidate for evaluating any differences in productivity as a function of fertilization regimen. ...

Aquaculture offers the opportunity for safeguarding local and global food security in the face of declining capture fisheries. However, the form of aquaculture that is commonly practiced in Kenya is characterized by the use of agrochemicals such as fertilizers that negatively impact biodiversity especially when effluents from fish ponds drain into water bodies. This study aimed to determine differences in the growth rate of Clarias gariepinus, an important aquaculture fish in Kenya, to assess plankton diversity, and to identify phytoplankton species associated with pollution under organic and inorganic fertilization regimens using chicken manure, Diammonium phosphate, and urea, respectively. Average growth rate calculated per day was higher in the organically-fertilized ponds at 0.06 cm/day, followed by inorganically-fertilized ponds at 0.05cm/day and then, the control at 0.04 cm/day. Average weight gain was higher in organically-fertilized ponds at 0.08 g/day followed by ponds fertilized with inorganic fertilizer at 0.07 g/day and the control, at 0.06g/day. There were significant differences in growth rate across fertilization regimens (length: F2, 264= 24.06, p = 0.0399; weight: F2, 264 = 20.89, p = 0. 0457). Specifically, although differences in growth rate of fish in organically and inorganically fertilized ponds were not significant, fish in fertilized ponds were on average, longer and weighed more than those in the control pond. Jaccard’s similarity index for phytoplankton was highest (0.38) between organically-fertilized ponds and control but lowest (0.25) between inorganically-fertilized ponds and control. Use of chicken manure produced the highest diversity of zooplankton (Shannon-Weiner’s H in organically-fertilized pond = 1.886; inorganic = 1.044, and control = 0.935). The use of DAP and urea produced the highest proportion of phytoplankton species associated with pollution. These results do not support the commonly reported notion that ponds fertilized using inorganic fertilizers are more productive. Findings suggest that the use of inorganic fertilizers may threaten biodiversity in aquatic ecosystems through the production of toxic algae.

Although significant breakthrough has been achieved in these countries with this type of integration, not much has been achieved in Africa except some countries like, Ghana, Malawi, Nigeria and Kenya (Eyo et al., 2006). Erick et al. (2013) suggested that livestock-fish integration is one of the most practicable solutions to food insecurity and malnutrition in East African community. In Ethiopia a few attempts have been made on the integration of fish with crop cultivation (Kebede Alemu, 2003;Lemma Desta et al., 2014). ...

Penerapan wanamina di Indonesia telah berlangsung sejak lama, namun perkembangannya relatif lambat. Adanya konflik kepentingan hingga rendahnya partisipasi masyarakat merupakan kendala yang selalu ada dalam pengembangan wanamina. Meskipun perkembangan penerapan wanamina relatif lambat, namun manfaatnya telah mulai banyak dirasakan oleh masyarakat, mulai dari peningkatan produktivitas budidaya, manfaat hasil samping budidaya, biaya pengelolaan yang rendah hingga manfaat ekologis bagi perlindungan pantai dan daya dukungnya terhadap perikanan tangkap. Peningkatan kualitas lingkungan merupakan manfaat yang paling banyak dirasakan oleh pembudidaya. Sementara jasa-jasa lingkungan dari keberadaan ekosistem mangrove lebih banyak dirasakan oleh masyarakat sekitar khususnya nelayan karena semakin meningkatnya keragaman dan kelimpahan sumber daya ikan. Berbagai upaya pengembangan tata kelola telah dilakukan untuk meningkatkan produktivitas dan manfaat ekonomisnya serta mengurangi limbah dan biaya produksi dalam budidaya. Pengaturan jenis mangrove hingga pemanfaatan limbah pertanian dan peternakan merupakan strategi yang semakin banyak dipadukan dalam budidaya dengan sistem wanamina. Fungsi perlindungan dan ketahanannya dalam tambak wanamina juga semakin dipertimbangkan dalam pemilihan jenis mangrove yang akan ditanam. Peranan praktis dari jenis vegetasi mangrove menunjukkan adanya dampak yang signifikan dalam pengendalian kualitas lingkungan, penyediaan pakan alami hingga daya dukungnya terhadap sumber daya perikanan secara umum. Potensi pemanfaatan jangka panjang berupa produksi kayu mangrove juga menjadi faktor penting yang perlu dipertimbangkan untuk menghindari konflik pemanfaatan mangrove di masa yang akan datang. Pengelolaan ekosistem mangrove dan tambak secara terpadu diharapkan mampu menjembatani kepentingan pemerintah dalam melindungi wilayah pesisir, petambak dalam melakukan kegiatan budidaya serta nelayan penangkap ikan yang kesemuanya merupakan pemangku kepentingan yang tidak dapat diabaikan.

The study on integration of tilapia and vegetable cultivation was conducted at Silkamba, in west shoa zone, Ethiopia. The Nile tilapia fingerlings were stocked (3/m2) in an earthen pond fertilized with cow dung and poultry excreta at 3:1 ratio. A control pond was maintained without fertilization. The seedlings of the tomato (Cochoro variety) and onion (Bombay red) were planted on twelve plots prepared adjacent to the ponds. The seedlings on six treatment plots were grown by addition of the fertilized fish pond water and control plants were supplied with the control pond water. Physico-chemical parameters like dissolved oxygen, pH, carbon dioxide, alkalinity and nitrate in the treatment pond remained within the required level for the growth of Nile tilapia. The water temperature was comparatively high which was more suitable for the production of fish food organisms as well as the fish growth in the pond. The level of nitrate and total phosphorus in the treatment pond was at the suitable level which enhanced the growth of plankton and benthic organisms in the pond. The bottom soil in the treatment pond showed comparatively high level of organic carbon and organic matter than the control pond. The number of tomato fruit and their size were higher in the treatment plots. Similarly the yield of onion from the treatment plots was higher than the control plot. The total yield of fish from the treatment was 27.22kg. The results on the analysis of expenditure and income indicated that the integration of vegetable cultivation using fish pond water alone was more profitable than the conventional method of vegetable cultivation with the application of fertilizer.
... Traditional Asian tilapia culture has used farm products and by products as fertilizers on integrated terrestrial/aquatic farms to promote primary production in ponds. The integration of livestock production with aquaculture provides an efficient means of utilizing nutrients in farm manures for the production of other consumable products [38] [39]. The same approach to nutrient cycling is at the core of western organic farming methods. ...

Growing global needs for food call for substantial increases in protein production in coming years, and for diligent conservation efforts. Manures from farm animals have been viewed both as a resource and as a waste product, but they are critically important sources of nutrients for organic and integrated farming and for traditional Asian aquaculture. Given constraints on livestock production and capture fisheries, careful development of the aquaculture industry is a necessity. The production volume and market share of tilapia are advancing extremely rapidly, and so too is the proliferation of misinformation and controversy. Culture and feeding practices differ widely, but feeding is usually recognized as the single largest cost to producers. Traditional Asian integrated farming practices involve the use of manures and other farm wastes to promote algae and zooplankton production, serving as a sole or supplemental nutrient source to the food chain that supports tilapia growout. Tilapia also ingest manures. The efficient use of nutrients from manures can have multiple benefits to integrated terrestrial agriculture and aquaculture, as long as product safety and quality are not compromised. With efficient use, handling of manures is simplified, fish production costs are reduced, fish nutrition can be improved, and potentially polluting materials are cycled constructively on integrated farms. Consumer and press reactions to the use of farm manures in food production can be highly polarized. Published responses cover a range of extremes, from enthusiastic endorsement to volatile reactions and outright rejection; in some areas this practice is considered to be more of a “PR (Public Relations) problem” than a health hazard. The perception in online public media that tilapia coming from ponds fertilized with manure are heavily contaminated with pathogens has not been supported by evidence. The perspectives of farmers in two major tilapia production areas (China and the Philippines) are included.
... In Kenya, integrated fish culture is still in nascent stages of development with demonstrational infrastructure present in state-owned institutions such as the LBDA in Kisumu and the KMFRI in Sagana and Sangoro (Fig. 9). Nevertheless, farmers have embraced the practice across the country where they use mainly chicken and cow manure for pond fertilization, and have recorded impressive performance in some areas (Ogello and Opiyo, 2011;Ogello et al., 2013). Studies on integrated fish culture on the Kenyan side of the Lake Victoria Basin reported that a 200 m 2 fish pond of O. niloticus fertilized with cow manure provided an additional per capita fish supply of 3.4 kg to a household of seven people for an average annual productivity of about 200 kg/ha/y (Denny et al., 2006). ...

The Kenyan aquaculture sector is broadly categorized into freshwater aquaculture and mariculture. Whereas freshwater aquaculture has recorded significant progress over the last decade, the mariculture sector has yet to be fully exploited. The Kenyan aquaculture industry has seen slow growth for decades until recently, when the government-funded Economic Stimulus Program increased fish farming nationwide. Thus far, the program has facilitated the alleviation of poverty, spurred regional development, and led to increased commercial thinking among Kenyan fish farmers. Indeed, national aquaculture production grew from 1,000 MT/y in 2000 (equivalent to 1% of national fish production) to 12,000 MT/y, representing 7% of the national harvest, in 2010. The production is projected to hit 20,000 MT/y, representing 10% of total production and valued at USD 22.5 million over the next 5 years. The dominant aquaculture systems in Kenya include earthen and lined ponds, dams, and tanks distributed across the country. The most commonly farmed fish species are Nile tilapia Oreochromis niloticus, which accounts for about 75% of production, followed by African catfish Clarias gariepinus, which contributes about 21% of aquaculture production. Other species include common carp Cyprinus carpio, rainbow trout Oncorhynchus mykiss, koi carp Cyprinus carpio carpio, and goldfish Carassius auratus. Recently, Kenyan researchers have begun culturing native fish species such as Labeo victorianusand Labeo cylindricus at the National Aquaculture Research Development and Training Centre in Sagana. Apart from limited knowledge of modern aquaculture technology, the Kenyan aquaculture sector still suffers from an inadequate supply of certified quality seed fish and feed, incomprehensive aquaculture policy, and low funding for research. Glaring opportunities in the Kenyan aquaculture industry include the production of live fish food, e.g., Artemia, daphnia and rotifers, marine fish and shellfish larviculture; seaweed farming; cage culture; integrated fish farming; culture of indigenous fishspecies; and investment in the fish feed industry.

The study compared the growth performance of Ctenopharyngodon Idella and Cyprinus carpio cultured under conventional management and integration of fish swine farming intended to optimize the biomass production from unit land in subtropical agro-ecosystem. The carp culture was integrated with swine production, where swine excreta was drained directly to the pond. The fishes in both treatments were fed thrice a day with locally formulated feed as a supplement at the rate of 2% wet body weight of fish fingerlings during the study period. The growth performance of carp fish in T1 (111.80 ± 10.07 g) was higher than T2 of 74.48 ± 6.29 g, and found significantly different (p < 0.05). In addition, this study although not significantly different the survival rate was found comparatively higher in fish swine integrated pond. The total fish production recorded was 3155.79 and 2076.42 kg/ha in fish swine integration system and conventional management, respectively. This study concludes that swine fish integration is feasible in subtropical area and there are possibilities to enhanced unit fish production.

In Africa, overhunting of tropical wildlife for food remains an intractable issue. Donors and governments remain committed to invest in efforts to both conserve and allow the sustainable use of wildlife. Four principal barriers need to be overcome: 1) communities are not motivated to conserve wildlife long-term because they have no formal rights to benefit from wildlife, or to exclude others from taking it on their land; 2) multi-species harvests, typical of bushmeat hunting scenarios, place large-bodied species at risk of extinction; 3) wildlife production cannot expand, in the same way that livestock farming can, to meet the expected growth in consumer demand; and 4) wildlife habitat is lost through conversion to agriculture, housing, transportation networks, and extractive industries. In this review, we examine the actors involved in the use of wildlife as food and discuss the possible solutions required to address urban and rural bushmeat consumption. Interventions must tackle use and conservation of wildlife through the application of context-relevant interventions in a variety of geographies across Africa. That said, for any bushmeat solution to work there needs to be concurrent and comparable investment in strengthening the effectiveness of protected area management and enforcement of wildlife conservation laws.
