Fish

The U.S. Bureau of Reclamation is boosting the amount of water flowing in the Snake River in an effort to help native fish between Palisades Reservoir and Shoshone Falls.

Michael Beus with the Bureau of Reclamation in Heyburn, Idaho told The Times-News that the faster, deeper flow will give native cutthroat trout an advantage over invasive rainbow trout.

The bureau has been increasing flows every year since 2004.

Many parts of the U.S. have been getting warmer over the past several decades, and also experiencing persistent drought. Wildlife often can't adjust. Among the species that are struggling is one of the American West's most highly prized fish — the cutthroat trout.

In springtime, you can find young cutthroats in the tiny streams of Montana's Shields Basin. Bend over and look closely and you might see a 2-inch fish wriggling out from under a submerged rock — the spawn of native cutthroats.

The Snake River's fall chinook salmon are making a comeback.

There were just 78 wild chinook salmon counted at the Lower Granite Dam in 1990. Last year, more than 20,000 of the wild salmon were counted, and 75,846 wild and hatchery-born fall chinook total.

Scientists say a voracious species of trout that entered Yellowstone Lake and decimated its native trout population appears to be in decline following efforts to kill off the invading fish.

Non-native lake trout were first found 20 years ago in the 132-square mile lake in the center of Yellowstone National Park. Crews have since caught and removed more than a million of the fish in hopes that cutthroat trout populations would rebound.

On Tuesday, scientists from the park and Trout Unlimited said those efforts are finally showing progress.

The Columbia River will remain drawn down at least until June because of the cracked Wanapum Dam in southeast Washington.

The ongoing issue with the cracked Wanapum Dam in central Washington is now creating a problem for migrating salmon.

It's not something we often think about, but as we go about daily life, we're constantly shedding little flakes of skin. So are animals and fish.

The Yakama Nation’s steelhead reconditioning program is like a retreat spa for fish. And it's changing the circle of life for the species.

New advisories from health officials in Washington and Oregon warn that some fish in the Columbia River aren’t safe to eat.

Canadian mining company Midas Gold says it's making progress on its Golden Meadows project near Stibnite, Idaho.  The company says it continues to advance the project on several fronts. The ultimate goal is to mine gold in the East Fork of the South Fork of the Salmon River.

Biologists are preparing to poison off all the fish in a stream in Yellowstone National Park ahead of an effort to restore native fish species to those waters.

Nonnative brown and rainbow trout have invaded and become established in Grayling Creek and its tributaries north of West Yellowstone, Mont.

This week, biologists plan to put small quantities of a toxin in the streams to kill off the nonnative trout. Treatments with the chemical Rotenone will continue for two to three years until all of the nonnative fish species are gone.

Chinook salmon haven't returned naturally to the Boise River for decades, since dams downstream on the Snake River blocked their passage.

But the Idaho Department of Fish and Game will be stocking 300 to 400 Chinook jacks in the Boise River Monday.

The jack salmon are young Chinooks that return to fresh water earlier than other spawning adults.

They're about half the size of typical Chinooks that return to rivers.

You can pick up a number of different Audubon-style guides if you're a bird watcher.  But it’s a different story when it comes to fish.  Many Idaho fish haven’t been studied.

That nice piece of fish you might order at a restaurant or pick up from the grocery store may not actually be the type of fish you think it is.

How much fish do you eat every week?  That’s a question Idaho’s Department of Environmental Quality wants to answer.  The agency has asked state lawmakers for funding to study that question.
