Population genetics of the Manila clam (Ruditapes philippinarum) in East Asia

Abstract The Manila clam Ruditapes philippinarum is the world’s second most important bivalve mollusk commercially farmed, whose indigenous populations are mainly distributed in the coastal areas of East Asia. However, with the development of commercialization, mixture of populations and loss of loc...
