Rising river temperatures, partly driven by land-use and climate warming, threaten the future of Fraser River salmon. It is vital that fisheries managers acquire tools that will aid their understanding of how rising river temperatures will impact salmon in the Fraser River. With my industry partner, I will build a novel mathematical temperature model for […]

Fraser River sockeye have become more difficult to manage due to climate change and increasing high adult in-river mortality events. Currently, managers use the difference between estimated lower river sockeye abundance at Mission hydroacoustic station and estimates of abundance attained on the spawning grounds through stock assessment; referred to as difference between estimates (DBE’s). Fraser […]

In 1995, proportions of several stocks of Fraser River sockeye salmon (Oncorhynchus nerka) began to enter the Fraser River system early to spawn creating uncertainty in mortality and spawning abundance estimates. This has created large problems for fisheries management in their attempt to protect less abundant stocks. To address this issue, Fisheries and Oceans Canada […]
