Overfishing of salmon has caused populations of wild salmon to decline. to combat this decline, salmon are raised in hatcheries, and then released to the wild. however, researchers have found that hatchery-raised salmon have reduced reproductive success in the wild, compared to wild salmon. they have also identified many genetic differences between hatchery-raised and wild salmon. which statement describes the most likely reason for the differences between hatchery-raised and wild salmon?
