    • Spawning data - Snake River sockeye salmon captive propagation

    Metadata Updated: May 24, 2025

    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. The fork length to the nearest mm, weight to the nearest gram, fecundity, and green egg weight to the nearest mg of every female spawned is recorded. The fork length to the nearest mm, weight to the nearest gram, milt weight to the nearest 0.01 gram, milt volume, spermatocrit, and milt motility of every male spawned is recorded. The eyed egg weight and % survival to the eyed stage for every batch of fertilized eggs is recorded. A record is maintained describing which male is crossed with which female.
