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. Data is collected by broodyear on % survival to eye, % survival to spawning, % survival to smolt, % survival to adult, % maturity as two year olds, % maturity as three year olds, and % maturity as four year olds. Age of maturity data is available by sex.
