A new microbattery no larger than a long grain of rice could help biologists track the movement of younger, smaller fish through Northwest rivers.
Whew, ok, we're a little excited. But this video from John Gussman is RAD. The Elwha dam removal, taking place in Washington's Olympic National Park, has been an inspiring story to cover. Now the chinook salmon are coming home and they are magnificent.
It’s going to be a record year for Columbia River fall chinook. With several weeks left in this year’s run, numbers are already close to beating the previous record set 10 years ago.
Low water levels in the Rogue River Basin could trigger a die-off of adult chinook salmon this summer from a natural, warm-water-related disease that largely has been kept in check the past 12 years.
An uptick in California sea lion activity this week set the stage for Oregon and Washington wildlife managers to corral nine of mammals in floating traps below the Columbia River’s Bonneville Dam.
The first Chinook salmon have crossed the final dam before entering Idaho. The salmon are expected to arrive from their journey up the Columbia River in smaller numbers this year.
State fish biologists in Idaho are blaming a water supply problem at the fish hatchery in McCall for the death of an estimated 60,000 Chinook salmon fry.
For all of the Clean Water Act's successes, it was never designed to control contaminants that have emerged since its passage in 1972. These pollutants are affecting the environment in new and different ways. Consider the feminized fish of Puget Sound.
For Northwest tribes, fishing for salmon is more than a food source, it's a way of life. Five populations of Pacific salmon are already on the brink of extinction and changes in the climate stand to make matters worse.
This week we launch our new segment: Sustainable You! We'll check in with Ecotrope blogger Cassandra Profita to answer your recycling questions. Also, find out how chinook salmon runs were this spring and get the latest installment in our series "Voices of Coal".
You might remember predictions of really high spring chinook runs this year. But, it turns outs, after all the returning salmon were tallied up, the numbers were not as high as everyone had hoped.
This time of year thousands of tourists start making their way to the San Juan Islands. Many of them pile onto boats and go out looking for the resident killer whales that are foraging for salmon in Puget Sound. Scientists used to think all that boating traffic was a major source of stress for the whales. But new research points to another factor that could be even more upsetting for them.
State fish managers are crafting a management plan for the Rogue River's fall chinook salmon to ensure that the basin's most robust salmon run stays that way.
Federal biologists have decided Endangered Species Act protection is not warranted for chinook salmon from the upper Klamath and Trinity rivers in Northern California and Oregon.
Transporting fish around dams is a challenge that's perhaps unique to the Pacific Northwest. It has had its successes, but on Southwest Washington's Cowlitz River, which has been dammed since the middle of the 20th century, reestablishing fish runs using trucks has been slow going.
Federal fish biologists are trapping feisty, 40 pound fall Chinook in a deep pool a few miles from the mouth of the White Salmon River and using a truck to move them above the dam before it is breached next month.
