Molecular Identification and Phylogenetic Tree Reconstruction of Marine Fish Species from the Fishing Port of Kutaradja, Banda Aceh

Abstract

The enormous potential of marine resources possessed by Banda Aceh Province is expected to be utilised optimally. Accuracy in marine fish resource identification is a critical requirement to support their utilisation and preservation in Banda Aceh Province. In this study, a molecular identification approach was carried out in addition to conducting a morphological identification, commonly used by several scientists. The results were 47 COI sequences generated representing 33 genera, 19 families, and five orders. From the resulting COI partial sequences, there is one potential haplotype from the Scombridae family (Auxis thazard), two potential haplotypes from the Carangidae family (Elagatis bipinnulata and Decapterus macarellus), and two potential haplotypes from the Serranidae family (Variola albimarginata and Cephalopholis sonnerati). This study is essential for fisheries biological studies and other fisheries studies to support the sustainable utilisation of marine fisheries potential in Banda Aceh.

The first report of DNA barcoding of commercially important fish in Nias Islands, Indonesia

“…The molecular identification research that identified Variola albimarginata and Plectropomus leopardus from the western Indian Ocean was conducted in Simeulue and the North Coast of Aceh. In these studies, these two groupers were identified as highly abundant fish and displaying remarkably similar morphology, thereby necessitating meticulous morphological identification procedures to prevent mislabeling (Batubara et al 2017;Fadli et al 2021;Andriyono et al 2022). The genetic diversity of demersal fish was in a very high category at 0.98 (Table 5), where the range of genetic diversity was from 0 to 1 (Ramadhaniaty et al 2018).…”
