Abstract
This study examined the morphometric and genetic variation of the blue swimming crab (Portunus pelagicus) along the eastern coasts of Bicol and Eastern Visayas, Philippines. Using morphological measurements and DNA barcoding techniques, specimens from Albay, Catbalogan, Ormoc, and Sorsogon were analyzed to determine population structure and genetic diversity. Results showed significant variation in body proportions and coloration patterns but minimal genetic divergence, indicating a single species stock. The findings highlight the importance of integrating morphometric and molecular approaches in fisheries …
