fish hatchery

This summer’s extreme drought is becoming increasingly deadly for fish in the northwest.

The state department of Fish and Wildlife had already lost about one and a half million juvenile fish in overheated rivers and streams in Washington at the end of July, due to this summer’s historically warm temperatures and low water levels.

For the first time in 20 years, the Wenatchee River in eastern Washington has opened for spring Chinook salmon fishing.

Wildlife officials say it’s a sign of successful management of the hatcheries program.

Washington state has banned hatchery-raised steelhead from three tributaries of the Upper Columbia River basin. The aim of these so-called "gene banks" is to maintain strongholds for wild fish, and the state plans to designate additional gene banks in the future.

So why were the state and federal governments back in court this week, defending the decision to place a new hatchery on the Elwha River as part of the dam removal process?

People on the West Coast have counted on fish hatcheries for more than a century to help rebuild populations of salmon and steelhead and bring them to a level where government would no longer need to regulate fisheries.

But hatcheries have thus far failed to resurrect wild fish runs and artificially bred fish have come to dominate rivers. Critics say their influx harms wild salmon and masks the fact that wild populations are barely hanging on.
