"Fraser River sockeye stocks have been experiencing productivity lower than the long-term average in recent years. Forecasts for these stocks have been prepared with Bayesian models and presented as probability distributions. These distributions represent the range of survival the stocks have exhibited historically. Environmental variation, especially warming associated with climate change, are incorporated into the forecast models for 10 sockeye stocks. In general, adding these environmental variables has the effect of reducing the forecast abundance when temperatures are warmer"--Abstract. Includes abstract in French.
