Species Profiles: Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (Pacific Northwest). Sockeye Salmon

摘要

Species profiles are literature summaries of the taxonomy, morphology, range, life history, and environmental requirements of coastal aquatic species. They are designed to assist in environmental impact assessment. Sockeye salmon always spawn in a lake associated with a river or in the outlet river. The young fish use the lakes for rearing. The brilliant red flesh is highly prized by commercial and sport fishermen. Washington State and the Columbia River are the southern limit of reproducing populations of sockeye salmon. Sockeye salmon are primarily plankton feeders. They appear to thrive best at temperatures of 10-15 deg C. Ocean distribution does not appear to be limited by salinity. Adults require gravel with adequate water circulation for successful spawning and egg hatching.
