Tribes monitor fish in nearshore ‘nursery’
LA CONNER— Nearly every day in the spring through early fall, somewhere in the Skagit basin and San Juan Islands, a crew from the Skagit River System Cooperative (SRSC) is sampling fish populations.
Rain or shine, in smooth waters or blustery wind, the crew pulls beach seines and sets fyke traps to count and measure fish before returning them to the water. Crew members also record water temperature, salinity, depth, velocity, substrate and vegetation. As a result, SRSC, the natural resources arm of the Swinomish and Sauk-Suiattle tribes, has a 15-year (and counting) comprehensive database of the way fish use nearshore habitat.
The nearshore is a nursery to a variety of fish including sculpins, perch, smelt, herring and salmon. Puget Sound chinook salmon, listed as “threatened” by the federal Endangered Species Act, depend on estuaries for extended rearing during outmigration.
Monitoring this habitat is a crucial, yet often underfunded, aspect of the salmon recovery effort, said Eric Beamer, SRSC’s research director. Without it, nobody knows whether a restoration project did what it was supposed to do. (more…)
