Salmonid hatcheries cause 'stunning' loss of reproduction

of wild populations. Studies such as this consider only the genetic background of fish and the effects of hatchery selection on those genetics, and not other issues that may also affect salmon or steelhead fisheries, such as pollution, stream degradation or climate change.

Blouin cautioned that these data should not be used as an indictment of all hatchery programs.

Hatcheries can have a place in fisheries management, he said. The key issue is how to minimize their impacts on wild populations.
