This document discusses research into the physiological processes that regulate senescence in sockeye salmon. It describes past research showing that senescence rate is influenced by environmental factors like temperature, climate, humans, salmon density, and stream toxins. Future research plans to focus on the cellular mechanisms of aging by fin clipping and tagging early and late arriving salmon in Hansen Creek, fin clipping daily, and sacrificing fish on days 6 and 7 post tagging to study physiological changes over time.
