Abstract

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.

Abstract

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.

Abstract

AbstrakGastropoda adalah salah satu organisme akuatik yang ditemukan di berbagai tipe habitat mulai dari perairan dangkal, berpasir, terumbu karang dan laut dalam. Gastropoda yang menetap di kawasan mangrove menentukan jenis substrat yang hidup di dalamnya. Tujuan dari penelitian ini untuk menganalisis struktur komunitas gastropoda sebagai bioindikator dan tipe substrat di Kawasan Ekowisata mangrove Gampong Baro, Kecamatan Setia Bakti, Kabupaten Aceh Jaya. Penelitian ini dilaksanakan pada bulan Februari hingga maret 2024, menggunakan metode purposive sampling. Pengambilan sampel dilakukan pada 3 stasiun dengan 5 kali pengulangan menggunakan transek 10 m x 10 m dengan plot 1x1. Hasil penelitian pada tiga stasiun di Kawasan Ekowisata mangrove Gampong Baro Kecamatan Setia Bakti Kabupaten Aceh Jaya, ditemukan 5 spesies gastropoda yang terdiri atas 3 famili dengan jumlah total sebanyak 301 ind. Kepadatan (D) gastropoda tertinggi terdapat pada stasiun III sebesar 23,2 ind/ m2.Nilai keanekaragaman (H) pada stasiun I 1,24 Stasiun II 0,26 Stasiun III 1,85. Nilai Keseragaman (E) pada stasiun I 0,60, Stasiun II 0,30, Stasiun III 0,60. Nilai Dominansi (C) sebesar 0,91 dan terendah 0,30. hal ini menunjukkan bahwa tingkat keanekaragaman gastropoda pada kawasan ini tergolong rendah, tingkat keseragaman juga rendah, dan terdapat spesies dari gastropoda yang mendominasi yaitu dari spesies faunus ater yang menjadi salah satu bioindikator lingkungan. Faktor fisika- kimia lingkungan masi dalam ambang batas kehidupan gastropoda. Kondisi substrat sangat berpengaruh besar terhadap kehidupan gastropoda.Kata Penting: Aceh Jaya, Kepadatan, Keanekaragaman, Keseragaman, Dominansi,.AbstractGastropods are aquatic organisms found in various types of habitats ranging from shallow waters, sandy waters, coral reefs and deep seas. 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,
