Phylogeography of anabas testudineus bloch, 1792 (pisces: anabantidae) in asia

Abstract

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 mitochondrial COI gene to examine the phylogeography of A. testudineus in freshwater Asia. The population sample was taken from South Aceh, Indonesia. The sample was extracted using a modified C-TAB protocol. In all, 48 sequences from the Genbank and three sequences from South Aceh were included in this investigation. Seven samples came from Indonesia, three from Malaysia, nine from Philippines, seven from Vietnam, eight from Thailand, ten from India, and four from Bangladesh. According to the findings, the sequences formed 17 different haplotypes. For every population, the haplotype diversity (Hd) value is 0.897. The genetic distance measuring the closest populations is 0.0007 between Indonesia and Philippines, whereas Indonesia and Vietnam populations are the furthest apart, at 0.0904. Between 0 and 0.0157 is the genetic distance within the population. Thus, the populations of A. testudineus in Aceh and Indonesia and the Philippines are genetically more similar.
