Salish Sea Ecosystem Conference

Understanding the dynamics of salmon populations is important for conservation and management, but the factors driving spatial and temporal variation in many salmon populations remain poorly understood. Understanding these patterns is important for many coastal First Nations, who play an important role in the monitoring and management of salmon in their traditional territories. Using data from 200 unique spawning locations on the Central Coast of British Columbia, we quantified patterns in abundance and coherence of salmon over space and time to measure the extent to which portfolio effects stabilize variation in stocks. We found strong declines in Sockeye Salmon abundance …
