"We compiled and integrated environmental and biological observations spanning the life cycle of Fraser Sockeye returning in 2018 through a two-day workshop. The most striking observations in recent years have been the extremely warm conditions Fraser Sockeye salmon have been exposed to in both freshwater and marine ecosystems. Such warm temperatures can affect salmon survival directly, given that they are adapted to cooler temperatures, or indirectly, through their effects on the ecosystems Fraser sockeye inhabit. Since most observations throughout the life cycle of the 2018 Fraser Sockeye returns align closely with conditions experienced by the 2017 returns, which exhibited very poor survival, we predict that returning 2018 Fraser Sockeye will also exhibit poor survival. Thus, we expect returns to fall towards the lower end of the 2018 Fraser Sockeye forecast distributions, particularly where temperature covariates were not included or did not have a significant effect on a stock’s forecast"--Abstract, p. v.
