The Setiu Wetlands and its surrounding is an important ecosystem especially in providing services and commodities to the local community. Many indigenous fishes inhabiting this Wetland are harvested for food and medicinal remedy but research on itsbiodiversity specifically the genetic distribution of the commercially important food fish species like chacunda gizzard shad Anodontostoma chacunda or is limited. Locally known as selangat, its population genetics was investigated by using mitochondrial DNA CO1 gene target. DNA template obtained from a total of 15 individuals revealed nine putative haplotypes. Our preliminary genetic baseline data revealed pair-wise genetic divergence between haplotypes ranged from 0.20% to 1.70% with an average of 0.90%.Haplotype and nucleotide diversity was relatively high (Hd= 0.8857 ± 0.0169; π = 0.0064 ± 0.0038), suggesting the populations of the A. chacunda at Setiu Wetland are in relatively good ‘health’. Haplotype sharing between the different localities indicates gene flow that lead to low level of population structure which is difficult to detect. More specimens from different locations of Setiu Wetlands should be included in future study, to elucidate genetic variation and distribution of the A. chacunda in Setiu Wetlands, and ultimately to assist in specific sustainable fisheries management and planning.
