Steelhead have been slowly disappearing from the Nisqually River for at least the last decade and the Nisqually Indian Tribe wants to know why.
There is plenty of good habitat for steelhead in the Nisqually watershed, so we think theyre running into problems in saltwater, said David Troutt, natural resources manager for the Nisqually Tribe.
But, we dont know that for sure. Tribal and state co-managers would like to see about 2,000 steelhead return to spawn
every year to the Nisqually, but since 1993, fewer than 1,000 have come back. Decades ago, the Nisqually River had the strongest run of steelhead in Puget Sound; more than 6,000 would return every year. Nisqually River steelhead are part of a stock that is currently being considered for listing under the federal Endangered Species Act.
To help determine the cause for the steelheads decline, tribal researchers are tagging about 50 juvenile steelhead with acoustic transmitters as they head out to sea. The transmitters will allow the researchers to track the steelhead after theyve left the river.
The tribes effort is part of the joint U.S. and Canadian Pacific Ocean Shelf Tracking Project. An array of acoustic receivers located throughout Puget Sound will track the fish as they begin their ocean migration. When a steelhead carrying an acoustic transmitter passes between a pair of receivers, its individual frequency is recorded and tracked for several hundred yards.
This project will help us to narrow down where the steelhead could be running into trouble, said Troutt. With better information, well have a better idea how to recover
these fish. E. OConnell
I guess it's not so cut and dried as some would have us believe eh?
