Study: Increasing risk from hatchery salmon

A collection of over 20 studies by leading university scientists and government fishery researchers provides mounting evidence that salmon raised in man-made hatcheries can harm wild salmon through competition for food and habitat.

The research volume, published in the May issue of Environmental Biology of Fishes, includes pieces from Alaska, British Columbia, Washington, Oregon, California, Russia and Japan.

The studies provide new evidence that fast-growing hatchery fish compete with wild fish for food and habitat in the ocean as well as in the rivers where they return to spawn.
