salmon

It’s been a one-two punch of low snowpack last winter and not enough rain this spring for many Northwest rivers. Warm temperatures and low river flows are causing problems for salmon making the return migration.

In rivers and streams across the Northwest, waters are reaching a tipping point for salmon. Salmon like water temperatures to be 68 degrees. Officials say water temperatures in June are what is normally expected in late August.

Jeannie Yandel talks with Mark Titus, director of a new documentary called "The Breach," about the inspiration for the film, Russ Busch.

The longstanding legal battle over maintaining dams and salmon in the Columbia River is back in court this week. On Tuesday, a new judge will hear arguments on the Obama administration's latest salmon plan.

A new federal recovery plan for Snake River sockeye salmon recognizes progress in rebuilding a species that nearly vanished in the 1990s.

It calls for moving into a new phase of recovery for Idaho's iconic fish – beyond preventing extinction.

Two Sea Lions Die In Trap At Bonneville Dam

May 2, 2015

Two California sea lions died in a trap this week at the Columbia River's Bonneville Dam after a door closed prematurely, confining them for hours.

Oregon Department of Fish and Wildlife spokesman Rick Hargrave said a veterinarian has determined the two sea lions were likely crushed to death by a 1,500-pound Steller sea lion that was almost three times their size.

With the door closed, the smaller sea lions were unable to hop out of the way. The incident took place sometime between Tuesday evening and early Wednesday morning.

To some people, sea lions are smart, lovable creatures that shouldn't be harmed in any way. To others they're loud, destructive pests that need to be controlled.

As sea lion populations grow, both sides have gripes about how these hulking pinnipeds are being managed on the Columbia River.

In the Northwest, fisheries managers move salmon around dams using trucks and cannons. Why not a tunnel under the city of Seattle?

The tunneling machine known as Bertha has been stuck beneath the Seattle waterfront since December  2013, stalling construction and racking up millions in cost overruns. 

One local engineering firm has a fresh idea for the fumbling tunneling project: Instead of moving Subarus through the heart of the city, the tunnel should be used by salmon. 

Tracking salmon as they move past Columbia River dams just got a little easier. Scientists are using a new tag so small that researchers can inject it with a syringe into the fishes' bellies.

Researchers at Pacific Northwest National Laboratory and the Army Corps of Engineers have been working with tags since 2001. This newest version is the smallest yet, about the size of two grains of rice. The older tags are three times heavier.

PORTLAND -- New research suggests sea lions are eating more salmon in the Columbia River than previously thought.

Data from tracking salmon over the past five years show a significant drop in survival below Bonneville Dam. Michelle Rub, a researcher with with the Northwest Fisheries Science Center, says preliminary numbers show survival dropping from 90 percent in 2010 to 55 percent in 2014.

SEATTLE -- If you can’t take the heat… head to the poles. That’s what fish are doing anyway.

A new study published in the ICES Journal of Marine Science looked at historical data for more than 800 commercial fisheries around the world and found that fish are heading to deeper waters and higher latitudes as the world's oceans warm.

As we bid the tourists adieu, we welcome back the cranes and construction.

Season 2 of Seattle’s waterfront development project starts Wednesday. It includes work from Colman Dock to the Aquarium, and holes in the ground already show the concrete face of the 1930s-era seawall, soon to be demolished.

The U.S. Department of Agriculture is on a salmon-buying binge.  It usually spends $6 million a year buying pink salmon. This summer, it is spending a total $39 million.

Going For Launch With The Salmon Cannon

Sep 24, 2014

WASHOUGAL, Wash. -- Salmon may soon have a faster way to make it around dams. There’s a new technology that’s helping to transport hatchery fish in Washington. It’s called the salmon cannon -- yes, you read that right.

First, let's set the record straight: there’s not really an explosion. But the salmon cannon does propel fish from one spot to another.

That was demonstrated Tuesday, when the salmon cannon transported fish from southwest Washington’s Washougal River to a nearby hatchery. The goal is to make the move easier on the fish, in three steps.

Biologists Try To Figure Out Large Fall Chinook Runs

Sep 23, 2014

Thousands of fall chinook salmon are swimming up the Columbia River every day right now. This year’s migration is expected to be one of the largest in recent years. Researchers aren’t sure exactly why fall chinook have made such a big comeback.

Salmon and steelhead restoration has been a big push throughout the Northwest -- from Puget Sound to coastal streams to the Columbia-Snake River Basin -- where fall chinook were nearly extinct by the 1960s.

Fisheries experts say the return of Chinook salmon to the Columbia River may not quite break records this fall as expected.
