Application of the Cytochrome-b gene region in Population Study of Striped Snakehead (Channa striata) by Molecular Approach

Snakehead fish with different geographical differences can have an impact on genetic diversity. DNA barcoding is a system designed to identify species precisely and accurately by using short standardized gene regions. This study aims determine the diversity of snakehead populations in four areas East Java. used Cytochrome b (Cyt b) sequence mitochondrial variation wild population Channa striata. The results barcodes c oxidase subunit I (COI) showed that all samples were validly C. striata (99.84-99.85%), while Cyt-b sequences had percentage identity same ranging from 99.74 100%. phylogenetic tree reconstructed MEGAX resulted separate clade strengthens similarity Brantas watershed.
