Association among growth, food consumption‐related traits and amylase gene polymorphism in the Pacific oyster Crassostrea gigas
Summary To examine further a previously reported association between amylase gene polymorphism and growth in the Pacific oyster Crassostrea gigas , ecophysiological parameters and biochemical and molecular expression levels of α‐amylase were studied in Pacific oysters of different amylase genotypes....
