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 harvested from Langsa district waters in Aceh province, Indonesia, based on DNA barcode data. It was conducted from June to December 2021, with the fish specimens collected from fishers at fish landing sites and the fish market in Langsa City, Aceh province. A total of 22 grouper sequences belonging to six species were generated, namely Epinephelus coioides, E. bleekeri, E. malabaricus, E. erythrurus, E. sexfasciatus and Mycteroperca poecilonotus (formerly Epinephelus poecilonotus). Genetic distance within these species ranged from 0.10 to 0.73% (average: 0.40%). Notably, E. malabaricus and E. coioides exhibited the closest genetic kinship (4.07%), while E. sexfasciatus and M. poecilonotus displayed the greatest genetic distance (19.33%). This study provides the first DNA reference for grouper in Langsa district, Indonesia, with significant implications for future sustainable grouper management.

The groupers are a group of demersal fish that live in tropical and subtropical areas and are mostly linked to coral reefs. The fish are highly valued in international markets and are subjected to overfishing in the wild. Accurate fish resource identification knowledge is essential for sustainable fisheries management. This research is aimed to generate a reference COI sequence library of grouper species caught in Simeulue and Banyak Islands, Aceh. The study was conducted from April-September 2021 at sixteen fish landing sites in Simeulue and Banyak Islands. In total, this study generated 70 COI sequences representing 20 grouper species. Epinephelus (54%) was the most prevalent grouper genus at the study site, followed by Cephalopholis (19%), Plectropomus (13%), Variola (12%), Hyporthodus (1%), and Anyperodon (1%). According to the IUCN classification, 17 species (85%) fall into the category of Least Concern, two (10%) fall into the category of Vulnerable, and one (5%) falls into the category of Data Deficient. The average genetic distance based on the Kimura-2-Parameter (K2P) between specimens was 0.51% at the species level and 8.34% at the genus level. Overall, this study has provided the COI sequence database of grouper for the Simeulue and Banyak Islands.

The gastropods that live in mangrove areas determine the type of substrate that lives in them. The aim of this research is to analyze the structure of the gastropod community as a bioindicator and substrate type in the Gampong Baro mangrove Ecotourism Area, Setia Bakti District, Aceh Jaya Regency. This research was conducted from February to March 2024, using a purposive sampling method. Sampling was carried out at 3 stations with 5 repetitions using a 10 m x 10 m transect with a 1x1 plot. The results of research at three stations in the Gampong Baro mangrove ecotourism area, Setia Bakti District, Aceh Jaya Regency, found 5 species of gastropods consisting of 3 families with a total of 301 individuals. The highest density (D) of gastropods was found at station III at 23.2 ind/m2. Diversity value (H') at station I 1.24 Station II 0.26 Station III 1.85. Uniformity Value (E) at Station I 0.60 Station II 0.30, Station III 0.60. The Dominance (C) value is 0.91 and the lowest is 0.30. This shows that the level of gastropod diversity in this area is relatively low, the level of averance is also low, and there are species of gastropods that dominate, namely the faunus ater species which is one of the environmental bioindicators. Environmental physico-chemical factors are still within the threshold of gastropod life. Substrate conditions have a big influence on the life of gastropods.Keywords: Aceh Jaya, Density, Diversity, Averance, Dominance,

Shark is a cartilaginous fish that is widely hunted because it has high economic value. The waters of Aceh are directly adjacent to the Indian Ocean and the Malacca Strait making it a preferred habitat for pelagic fish, especially sharks. Information on shark species landed in the waters west and east of Aceh is very limited due to difficulties in identification and commonly used local names. This study aimed to determine the types of sharks landed in Banda Aceh, Meulaboh, Langsa, Southwest Aceh and Simeulu and to find out specifically what species of sharks are most often landed in Aceh waters. Primary data gathering consisted of four stages, namely sample collection, identification using identification books, molecular identification cytochrome oxidase subunit I (COI) and phylogenetic analysis. The results of the molecular analysis of 46 tissue samples from five locations identified 13 species of sharks, namely Carcharhinhus sorrah, Carcharhinhus amboinensis, Triaenodon obesus, Isurus oxyrinchus, Sphyrna zygaena, Sphyrna lewini, Loxodon macrorhinus, Hemipristis elongaria, Stagostoma fasciatum, Nebrius ferrugineus, Chilloscyllium punctatum, Isurus oxyrinchus, Alopias pelagicus, Alopias supercillosus and 1 species of rays, namely Rhynchobatus australiae. Phylogenetic tree reconstruction using the Neighbor Joining method of 610 basepairs consisting of two large clades separates the species Alopias pelagicus and Isurus oxyrichus with Carcharhinus sorrah, Sphyrna lewini, Loxodon macrorhinus and Rhyncobatus australiae with boostrap values of 87% and 64%. The haplotype diversity shown ranged from 0.667-0.889 while the nucleotide diversity ranged from 0.001-0.097. These values indicates high diversity because of the variance in the number of species found.Keywords:BarcodeCOISharks catchAlopias supercillosusSphyrna lewini

Octopus is a biota with very high economic value, so it has become commercial and has high demand. Breuh Island is one of the suppliers of fresh octopus, both within and outside the Aceh region. One step to increase the selling price and long shelf life is to make the octopus into a pickled product. Kube Mangat is the fishery entrepreneur specializing in octopus processing in the Breuh Island area. Kube Mangat produces processed octopus in a very traditional way, both in terms of drying and storing the product. This service utilizes methods derived from research results, including proximate tests and microbiological tests. The results of this research explain that salted octopus products can last in excellent quality until the fourth month. The results of the research were disseminated to Kube Mangat partners and the Gampong Gugob community. This service has also successfully assisted Kube Mangat in obtaining a PIRT number, halal certificate, and trademark registration at the Ministry of Law and Human Rights. Because Kube Mangat has standardized its product packaging, it is currently suitable for entering the modern market.

Octopus cyanea is an ecologically and economically important cephalopod with wide larval dispersal influenced by ocean currents. However, geographic isolation among island clusters in northern Sumatra may restrict gene flow and shape population structure. This study investigated the genetic diversity and connectivity of O. cyanea from five populations (Aceh Island, Weh Island, Banyak Island, Simeulue Island, and Nias Island) using mitochondrial cytochrome c oxidase subunit I (COI) sequences. A total of 21 individuals were successfully amplified, yielding 651 bp fragments. Sequence analysis revealed 11 haplotypes across populations, with haplotype diversity (Hd) ranging from 0.285 in Banyak Island to 0.800 in Aceh Island, and nucleotide diversity (π) between 0.001 and 0.009. Pairwise genetic distances varied from 0.000 to 0.004, with the highest divergence observed between Simeulue Island and Nias Island (0.004), while Aceh Island and Weh Island showed no differentiation. AMOVA indicated that most genetic variation occurred within populations (68.74%), with an overall Fst of 0.315, suggesting low to moderate genetic structuring. The haplotype network demonstrated shared haplotypes among four populations, whereas Simeulue Island harbored unique haplotypes, indicating partial genetic isolation. These results highlight substantial genetic connectivity among O. cyanea populations in northern Sumatra, facilitated by larval dispersal via ocean currents, but also emphasize localized divergence in Simeulue Island. The findings provide critical baseline data for developing ecosystem-based fisheries management, supporting shared stock strategies while accounting for population-specific conservation needs.

Bottlenose Wedgefishes are fish that belong to the subclass Elasmobranchii, which are cartilaginous fish. West Aceh waters are one of the areas directly connected to the Indian Ocean. Bottlenose Wedgefish can be found in the Indian Ocean. Some information on Bottlenose Wedgefish DNA has now developed molecular approaches, which provide a fast and precise alternative to identify species. This research activity aims to report the presence of Bottlenose Wedgefish sharks (Rhynchobatus australiae) and analyze the relationship between Bottlenose Wedgefish sharks found in West Aceh with other regions. This research was conducted from October to December 2021. The specimens were taken from the Ujong Baroh Fish Landing Site (PPI), West Aceh, and analyzed at the Laboratory of Genetics and Aquatic Biodiversity, Faculty of Marine and Fisheries, Syiah Kuala University. The results of the study resulted in several conclusions, namely the Query Cover value of Meulaboh 1 and Meulaboh 2 samples of 93%. The Ident value of 99.70%-99.85% indicates that the same species is R. australiae. Thymine (T) nucleotide composition is 30.8%, Cytosine (C) is 24.9%, Adenine (A) is 27.4%, and Guanine (G) is 16.9%. Based on the results of phylogenetic tree reconstruction, the relationship between Rhynchobatus australiae Meulaboh samples 1 and 2 has a close kinship with Rhynchobatus australiae from India1, India2, India3, Malaysia1, Indonesia3, and Indonesia5. This research confirms the presence of Rhynchobatus australiae in West Aceh and establishes a close genetic link to regional populations.
