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. The research also raises questions about whether the ocean can supply enough food to support future increases in hatchery fish while still sustaining the productivity of wild salmon.
