Rapid morphological divergence of cultured cod of the northwest Atlantic from their source population

The performance of aquaculture escapees in the wild depends in part on how their morphology differs from that of wild fish. We compared farmed Atlantic cod Gadus morhua morphology to that of wild cod from the same ancestral population. Traditional and geometric morphometrics showed that farmed cod h...
