Numerous decades-old sturgeon dying in the Columbia River near the Tri-Cities are prompting a proposal to close catch-and-release fishing for the species. The proposal is scheduled for consideration today by the Columbia River Compact, the state agencies and tribes that co-manage the fisheries.
FISHING -- Numerous decades-old sturgeon being found dead in the Columbia River near the Tri-Cities are prompting a proposal to close catch-and-release fishing for the species. The proposal is scheduled for consideration on Thursday, July 16, by the Columbia River Compact. "We don't know the...
Tribal and state fisheries researchers landed a big incentive this fall to continue their work on reviving white sturgeon numbers in the Columbia River upstream from Kettle Falls. A sturgeon, 9 feet long and weighing 507 pounds, was captured and released by Colville Confederated Tribes fisheries staff in September near Northport.
The population of North America’s largest freshwater fish living between a dam on the Idaho-Oregon border and another in Eastern Washington was holding steady from 14 years ago, according to information from an Idaho utility’s survey. Hundreds of miles downstream in the Columbia River below all of the dams, sturgeon numbers are increasing under a ban on catch-and-keep fishing, according to a report from the Washington Department of Fish and Wildlife.
SPOKANE — The eggs of endangered Kootenai River white sturgeon in Idaho and Montana are less likely to hatch in the river because of flow changes caused by Libby Dam and other human actions, according to a new report by the U.S. Geological Survey.
RIGGINS, Idaho – The Idaho Department of Fish and Game is conducting a three-year study to determine if fishing hooks and lines ingested by sturgeon are adversely affecting the health of the long-lived fish. The Times-News reported that biologists are capturing white sturgeon in the Snake River inside Hells Canyon and using a mobile X-ray machine to find out what kind of fishing tackle is inside them.
SEATTLE – A Seattle man who came across a giant dead fish as he waterskied on Lake Washington says he first thought it might be a shark. Keith Magnuson now says he thinks the roughly 8-foot-long creature is a sturgeon.
Spilling water over Libby Dam may have aided endangered Kootenai River sturgeon this spring by coaxing the giant fish upriver to better spawning grounds. The U.S. Army Corps of Engineers wrapped up the weeklong spill tests early Sunday. The pulse of water – designed to mimic historic spring flows – prompted some sturgeon to swim upstream to gravelly reaches of the river, according to preliminary reports. Biologists believe that fertilized sturgeon eggs have a better chance of survival in the gravels, rather than the sandy river bottom around Bonners Ferry, where the eggs get smothered by silt.
Sea lion predation on sturgeon in the Columbia River at Bonneville Dam increased for the sixth straight year in 2011 with more than 3,000 estimated killed. Monitors for the U.S. Army Corps of Engineers observed for 3,315 hours this winter and spring and saw 1,353 sturgeon caught by sea lions.
