Returns and forecasts of Rivers and Smith Inlet sockeye salmon, 1970-2009. 2010 Canadian Marine Ecosystem Status and Trends Report

Historically, the Rivers and Smith Inlet sockeye salmon stock formed one of the most valuable salmon fisheries in British Columbia, however it declined precipitously in the early 1990s. This decline is the result of poor marine survival during the migration through this ecozone and into the Gulf of Alaska; however the specific cause and location of this mortality is unknown.
