Germplasm evaluation and identification of the population source of hard clam ( Mercenaria mercenaria ) in China using SSR and COI markers
In aquaculture, good germplasm resources are nearly decisive for its development. The hard clam (Mercenaria mercenaria), a significant marine aquaculture bivalve in China, has flourished quickly since being introduced from North America in 1997. However, for numerous reasons, it has suffered from ge...
