The octopus exhibits highly developed defensive adaptations, including the ability to camouflage itself to deceive predators. It undergoes two larval stages, during which it experiences wide dispersal influenced by ocean currents and oceanographic characteristics. One region with complex current dynamics is the northern waters of Aceh, specifically...

The Scombridae family represents one of the most commercially valuable groups of pelagic fish, widely consumed across the globe. Despite their economic importance and high market demand, scientific data on Scombridae species in Aceh remains scarce. This study aimed to document Scombridae landings from Aceh waters. Fish samples belonging to the Scom...

Snappers (Lutjanidae) are a group of reef fishes with high commercial importance in Indonesia. However, there is currently a lack of available information on the bioecology and genetics of these snappers. The present identification of snapper species relies primarily on morphological differences, frequently leading to misidentification due to the h...

Clarias batrachus is native species from the Clarias genus that has significant economic value in the world, including Indonesia. The genetic relationship between C. batrachus populations in Asia has not been intensively studied. This study used the mitochondrial COI gene as a marker to examine the phylogeography pattern of Clarias batrachus in Ind...

Macrozoobenthos is a sedentary aquatic biota and is often used as a bioindicator for assessing water conditions. Therefore, this study aimed to investigate the species diversity of the macrozoobenthos and to analyze the heavy metal contamination in Faunus ater in the Rasian and Asahan estuaries in Aceh Province, Indonesia. The sampling was carried...

The painted spiny lobster, Panulirus versicolor, is an economically spiny lobster species on Simeulue Island. Fishing pressure on this species is suspected of experiencing overfishing, with indications that its size is getting smaller during the fishing season. Therefore, it is necessary to manage existing lobster resources. Several aspects that ne...

Anabas testudineus, the climbing perch, is a valuable and well-liked freshwater fish with significant commercial worth. This fish is found in Indonesia and other parts of Asia. Nonetheless, there hasn't been much research done on the genetic relationships across Asian populations of climbing perch. Thus, the aim of this work was to use the mitochon...

Groupers are among the fish groups that are difficult to recognize due to their high morphological similarities. Therefore, molecular techniques, particularly DNA barcoding, are extensively utilized to differentiate this fish group. This study aimed to analyze and validate six grouper species belonging to the Epinephelidae family that were harveste...

Octopus is a commodity that has important economic value and high export value. Gugop Distric is one of the producers of octopus in the form of fresh products and processed products developed by Kube Mangat. It is said that the octopus species in Indonesia are dominated by Octopus cyanea , but there is no scientific certainty for the type of octopu...

Lutjanus kasmira is one of the snappers occupying and commonly found in the Arabian Sea and the Bengal Strait. The purpose of this study was to examine the comparative phylogeography pattern of Lutjanus kasmira in the Bengal Strait and the Arabian Sea using the mitochondrial COI gene as a marker. The population sampled of Indonesia was taken from f...

Octavina C, Ramadhaniaty M, Daulay RE, Dewiyanti I, Ulfah M. 2023. Genetic variation and population structure of brachiopods, Lingula anatina Lamarck, 1801 in the Northern Aceh shore. Biodiversitas 24: 3951-3959. Lingula anatina is one of the brachiopods recognized as one of the most primitive groups with a fossil record from the early Cambrian per...

Understanding the patterns of genetic diversity of species and precise stock identification are important in fisheries conservation management. However, studies on genetic diversity, connectivity, population structure, and gene flow of groupers within the Indo-Malaya Archipelago (IMA) waters are limited. The objective of the present study was to ex...

Sea cucumber (Holothuria atra) was used as a reducing and capping agent in the green synthesis process to produce silver nanoparticles (AgNPs). The antioxidant activity of the generated silver nanoparticles was then evaluated. Seacucumber extract was mixed with the AgNO3 solution and homogenized using a magnetic stirrer to create the silver nanopar...

This study aimed to examine the influences of the Indian Ocean Dipole (IOD) on rainfall in three districts in South Aceh. The analysis was undertaken using Dipole Mode Index (DMI) data and five years of rainfall (2016 to 2020) in West Labuhan Haji, Tapak Tuan, and Bakongan areas. This research employed a correlation analysis and the Principal Compo...

Environmental DNA (eDNA) methods are increasingly viewed as alternate or complementary approaches to conventional capture-based surveys for marine conservation and fisheries management purposes, especially at large spatial scales in mega-biodiversity regions such as Indonesia. Decapod crustacean distribution and diversity across Indonesia are still...

Grouper is one of the economically important fish groups in the Simeulue and Banyak Islands. However, data on the diversity of the grouper in this region is still limited. This study aimed to inventory the commercially important grouper in Simeulue and Banyak Islands. Sampling was carried out in April - September 2021 at sixteen locations around Si...

The coral hind grouper (Cephalopholis miniata) is one of the essential fisheries commodities in Indonesia and the Aceh region. However, scientific data on its morphometrics and biology are limited. This study aimed to observe the morphometric, meristic, length frequency distribution, sex ratio, gonad development stage, gonad somatic index, and...

The current research reports the length-weight relationships (LWRs) and Fulton’s condition factor (K) of three grouper species, namely: areolate grouper (Epinephelus areolatus), blacktip grouper (Epinephelus fasciatus), and honeycomb grouper (Epinephelus merra) harvested in the northern coast of Aceh, Indonesia. The fish samples were gathered from...

The groupers, locally known as “kerapu” in Indonesia, are commercially valuable fish in Indonesia, including Aceh. The groupers are the first fish family to be plundered in most countries’ fisheries industries. However, the biodiversity information of the groupers fished in Aceh is limited. This study was aimed to inventories the grouper species la...

Crassostrea gigas is a Pacific oyster that has the largest size among the other oysters. This oyster is most often found because of its ability to adapt to a variety of environments. Krueng Cut is an estuary area that gets a lot of nutrient input from sea water because it is directly adjacent to the ocean. This condition makes this area has a high...

Indonesia is recognized as one of the territories that have the highest reef fish biodiversity in the world. One of the commercially valuable fish in this area is the groupers (locally name "kerapu"). At least 76 grouper species have been reported in Indonesian waters, with three species were categorized into "vulnerable", five species "Data Defici...

Mangrove ecosystem as a feeding ground contributes to habitat complexity and diversity of the macrofauna, while bivalves are dominant in this ecosystem.
