Just in time for the statewide lowland lakes opener and the beginning of trout season, the Washington Department of Fish and Wildlife (WDFW) is conducting a first-of-its-kind study to evaluate the movement and behavior of triploid and diploid rainbow trout in 29 Western Washington lakes — and we’re asking for help from the angling public.
Triploid trout — so called because they have three sets of chromosomes instead of the normal two (diploid) — are sterile fish that WDFW stocks in some lakes to help reduce interaction with native species living in the same waters.
