First Sockeye Makes Migration
The first sockeye salmon of the year has made the 900-mile migration from the Pacific Ocean to Redfish Lake in central Idaho.
The adult male was trapped Tuesday at Redfish Lake Creek. In July, three adult sockeye were observed crossing Lower Granite Dam, 400 miles downstream on the Snake River. It can take up to a month to make the journey from the dam to the lake.
Idaho Department of Fish and Game biologists said the 24-inch fish appears to be of wild origin. If that is the case, it was produced by the “residual” form of sockeye that inhabit Redfish Lake.
Residuals can produce oceangoing offspring even though they spend their entire lives in the lake. The fish most likely left Redfish in 1996.
The male will be incorporated in the 1998 spawning program at Fish and Game’s Eagle Fish Hatchery. In addition, sperm from the fish may be frozen for future use.
