QTL for resistance to summer mortality and OsHV-1 load in the Pacific oyster (Crassostrea gigas)
P>Summer mortality is a phenomenon severely affecting the aquaculture production of the Pacific oyster (Crassostrea gigas). Although its causal factors are complex, resistance to mortality has been described as a highly heritable trait, and several pathogens including the virus Ostreid Herpes vir...

P>Summer mortality is a phenomenon severely affecting the aquaculture production of the Pacific oyster (Crassostrea gigas).
