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 waters of Aceh are surrounded by three major water bodies: the Andaman Sea, the Indian Ocean, and the Malacca Strait. Differences in current patterns extend the distribution range and contribute to the species diversity. Fish from the Scaridae family are among the species that thrive in these environments. The family Scaridae (Rafinesque 1810), commonly known as parrotfish, inhabits tropical seas, including the Pacific, Indian, and Atlantic Oceans, and is often found in coral reef areas. Parrotfish play a crucial role in maintaining coral reef health as one of the herbivorous fish species. This study aims to analyze the morphometric variation of five parrotfish species harvested from the Northern waters of Aceh. Traditional morphometrics using 12 measurement characters were applied to 60 fish samples from five species of the Scaridae family (Chlorurus capistratoides, Chlorurus sordidus, Scarus ghobban, Scarus niger, and Scarus rubroviolaceus). The results showed that Scarus rubroviolaceus shares four similar characters with Scarus ghobban: ED, HL, CPL, and PFL; it also shares four characters with Scarus niger: ED, HL, CPL, and SNL. Chlorurus capistratoides shares three similar characteristics with Scarus niger: CPL, ED, and PFL. In addition, the results of the DFA analysis revealed that Scarus ghobban and Scarus niger exhibit the highest degree of similarity in morphometric traits, particularly in HL, SNL, DFBL, ED, and PFL. Furthermore, Scarus rubroviolaceus demonstrates a slight overlap with Chlorurus capistratoides, while Scarus niger shows a minor overlap with Scarus rubroviolaceus. This study provides morphological diversity of parrotfish species in the northern Aceh waters.Keywords:Aceh watersmorphometricsParrotfishMeasurement charactersDFA

Ectoparasite infections are a common problem in small-scale aquaculture, exerting a substantial influence on fishery production. In the context of Indonesia, the two prevalent fishery commodities are whiteleg shrimpLitopenaeus vannameiiand mud crabScylla serrata. These species are extensively cultured within Aceh province, using traditional and semi-intensive aquaculture ponds and there are no reports on ectoparasites in these two species of crustaceans. Therefore, this study aimed to analyze the intensity and prevalence of ectoparasites in mud crab and whiteleg shrimp from Aceh between August to December 2022. Mud crab samples were collected from three locations, namely Langsa City, East Aceh, and North Aceh districts, while whiteleg shrimp samples were sampled from coastal ponds in Banda Aceh, Aceh Besar, and Aceh Jaya districts. The samples were collected over five months, and a total of 300 for each species were examined microscopically by scraping the swimming legs body, and gills. Furthermore, macroscopic-sized and microscopic-sized ectoparasites were observed using stereo and binocular microscopes, respectively. The results showed that five species of ectoparasites were recorded during the study, namely Octolasmis sp., Vorticella sp., Epistylis sp., Oodinium sp., and Zoothamnium sp. Mud crab exhibited infestations of Octolasmis sp., Vorticella sp., Epistylis sp., and Oodinium sp., while whiteleg shrimp were infested byVorticellasp.,Epistylissp., andOodiniumsp. In this study, the highest intensity for crab and shrimp was recorded inOctolasmissp. and Epistylissp., in November and September, respectively. The gills showed higher intensity compared to other infested organs and based on sample origin, crab and shrimp from Langsa and Banda Aceh Cities had higher results compared to other locations.The prevalence of ectoparasites exhibited a high value, reaching 100%, showing that crustacean samples were infested by ectoparasites. Therefore, the intensity of ectoparasite was varied according to sample of origin, time of sampling and infested organs. The samples of both crab and whiteleg shrimp from all locations consistently exhibited ectoparasite infestations throughout the entire study period.Keywords:Octolasmis sp.Vorticella sp.Epistylis sp.Oodinium sp.Zoothamnium sp.

Global warming is caused by increased carbon emissions into the atmosphere resulting from burning oil, gas, and other fossil fuels. Subsequently, the carbon gas enters the waters through a diffusion process facilitated by the concentration of gases in the air, which is higher than in the waters. The outcome of this process is a decrease in water acidity, leading to a lower pH, which can disrupt the life of aquatic biotas. Therefore, this study aims to analyze the effect of decreasing of pH on the growth, survival, and physiological conditions of barramundi (Lates calcarifer). To achieve this objective, seven pH levels were tested, namely pH of 7.24 (control), pH 6.74, pH 6.24, pH 5.74, pH 5.24, pH 4.74, and pH 4.24. Every treatment was performed with four replications, and the fish was reared for 30 days in the respective tested pH. The reared madia is sea water with a salinity of 22 ppt. The experiment was conducted in the laboratory of fish breeding Faculty of Marine and Fisheries, Universitas Syiah. The results showed that a decreasing in pH had a significant effect on the growth performance and hematological condition of barramundi (P0.05), but its had no significant effect on survival (P0.05). The experimental fish could survive at pH 4.24, but their growth and hematological conditions were disrupted below 6.24. Therefore, it was concluded that the lower threshold value of pH for barramundi was 6.24.Keywords:Global warmingOcean aciditypHFisheries productionPhysiological disturbance

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
