Gene rescue captive broodstock program was established for ESA-listed endangered Snake River sockeye salmon from Redfish Lake, Idaho. The program has consisted of taking most of the remaining gene pool into captive culture at specialized conservation hatcheries at the Manchester Research Station and the Idaho Department of Fish and Game Eagle Hatchery. Fish are being released to native habitats as part of recovery efforts. Information on the number of eyed eggs, juveniles, and adults received into the program is maintained and summarized by year. The production of adults spawned, adults transferred to Idaho for release, green eggs taken, and eyed eggs shipped to Idaho and Oregon facilities for restoration activities is also annually summarized.
