- Research was conducted during 1990 to assess the feasibility of biologically manipulating physiological development and migratory behavior of yearling spring chinook salmon, Oncorhynchus tshawytscha. At Dworshak National Fish Hatchery, one treatment group was exposed to a 3-month advanced photoperiod schedule for 13 weeks preceding release to accelerate smolt development. Another group was exposed to the same advanced photoperiod schedule, but additionally was reared at an elevated water temperature (11.9°C) for 10 days prior to release. At Leavenworth National Fish Hatchery, a treatment group was exposed to a 3-month advanced photoperiod schedule for 17 weeks. Gill Na⁺-K⁺ATPase development and migratory performance were described for all groups. The treated fish which were the most physiologically advanced at release were detected in the highest proportions at collector dams and also migrated fastest downstream--similar to results obtained in 1988 and 1989.
