The Salish Sea Science Roundtable online speaker series continues on Tuesday, June 30 from 12:30 – 1:30 pm.
Enhancement of Pacific salmon stocks through the use of hatchery production is one approach to support vulnerable stocks and harvest. Integrated hatcheries support these goals by adding artificial spawning habitat to natural habitats, which produces elevated egg-to-release survival rates. However, this also creates risks of genetic effects within the integrated stock as different habitats have the potential to select for different trait distributions. Understanding how these effects translate to long-term fitness costs for integrated stocks is complicated by difficulties in separating genetic and environmental effects on hatchery-mediated trait variation in Pacific salmon. This presentation by Tim Healy with Fisheries and Oceans Canada will explore recent work through the Pacific Salmon Strategy Initiative, assessing genetic or heritable effects of hatchery production in British Columbia.
Roundtables occur virtually each month as a way to share emerging science that is shaping Salish Sea ecosystem recovery.
This event is free, but registration is required.
