Spatial estimates of juvenile Pacific salmon (Oncorhynchus spp.) abundance in the Strait of Georgia / by Patrick L. Thompson and Chrys M. Neville.: Fs97-6/3597E-PDF
"We provide spatial estimates of the distribution of juvenile fish in the Strait of Georgia for all five species of Pacific salmon. These estimates were generated using a spatiotemporal generalized linear model and are based on standardized fishery-independent survey data from the Strait of Georgia juvenile Pacific salmon pelagic trawl survey from 2010 to 2020. We provide predicted catch per unit effort (CPUE), year-to-year variation in CPUE, and prediction uncertainty, for both summer (June-July) and fall (September-October) at a 0.5 km resolution, covering the majority of the strait. These results show that the surface 75 m of the entire Strait of Georgia is habitat for juvenile Pacific salmon from June through early October, but that distributions within the strait differ across species and between the early summer and fall. While there is interannual variability in abundances and distributions, our analysis identifies areas that have consistently high abundances across years. Results illustrate juvenile habitat use in the Strait of Georgia for the five species of Pacific salmon and can support ongoing marine spatial planning initiatives in the Pacific Region of Canada"--Abstract, page iv.
