Hatchery Salmonids and Migration

Led by Andrew Berdahl, University of Washington School of Aquatic and Fishery Sciences
Collaborators include the Washington Department of Fish and Wildlife.

The team is testing the “pied piper hypothesis.” Large releases of young salmon from hatcheries might alter the natural timing of young wild salmon and reduce their survival. This collaboration between academic and tribal and state co-managers will use 15-years of data to examine this influence, then test findings using experimental releases. Results could improve hatchery release timing to benefit wild salmon survival
