Survival estimates for southern BC salmon populations. (A and B) Freshwater and early marine survival for sockeye and steelhead populations. (C) Freshwater estimates for Chinook and coho. Freshwater survival is from the release site to the river mouth subarray and early marine survival is from the river mouth to exit from the Salish Sea (operationally defined as the QCS and JDF marine lines). Error bars indicate ±1 SE on survival estimates. Horizontal bands in B show bracketed estimates of early marine survival arising from uncertainty in the fixed value of p assumed for the QCS and JDF lines (SI Materials and Methods). Rearing origin (H, hatchery; W, wild; U, unknown) is indicated below the bar for each population. “No data” indicates tagging did not occur in that year.
