Oregon State University study finds salmon hatcheries produce genetically different fish

New research from Oregon State University suggests hatchery-raised salmon, which are bred to help bolster wild stocks in B.C. and elsewhere, are genetically different from the populations they’re introduced into. Researcher Michael Blouin says scientists have known for some time the offspring of wild and hatchery-raised salmon are less adept at surviving in the wild, negatively affecting the health of wild populations. The question is, what is it about hatcheries that create fish believed to be inferior at surviving in the wild? Read the rest here 09:27
