In the early 1990s, Redfish Lake sockeye salmon from the Sawtooth Basin in Idaho were on the brink of extinction, and they were listed as endangered under the US Endangered Species Act in 1991. To prevent extinction, a gene rescue captive broodstock program was established for the stock that 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. Efforts through the decade of the 1990s consisted of developing techniques for successful culture of sockeye salmon to adulthood, establishing rearing and spawning protocols to ensure preservation of stock diversity, and habitat enhancement at the rearing lakes. In the early 2000s, the program began to include a demographic focus to boost the population through rearing and release of enough juveniles to produce some adult returns. For the last few years, NWFSC eyed egg production has resulted in over 150,000 smolts being released into the Stanley basin annually for recovery, with plans to increase NWFSC eyed egg production to support release of half a million smolts in the Stanley Basin by 2017. In 2011, and for the fourth year in a row, record numbers of sockeye adults have returned to their native home in Idaho. This work is collecting data on the length, weight, and survival of sockeye salmon ponded in chilled and unchilled water crossed with fish sourced from Burley Creek Hatchery Broodstock and Eagle Hatchery Broodstock.

All fresh mortalities larger than 100 mm are sent to Fish Health for pathology. Autopsy data is maintained on their database.

This work is collecting data on the length, weight, and survival of sockeye salmon ponded under two different incubation temperature profiles.

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.

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.

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. Raw data on rearing density, loading density, water temperature, ration, and feed size may be available. Raw data on administration of therapeutic drugs may be available.

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.

Fish are being released to native habitats as part of recovery efforts. The fork length to the nearest mm and weight to the nearest gram of a subsample of fish is recorded on an approximately quarterly basis.

NOAA Fisheries is a cooperator with the Washington Department of Fish and Wildlife and the Lummi, Nooksack, and Stillaguamish Tribes in a 10-year program to rebuild the South Fork Nooksack River spring Chinook and Stillaguamish River fall Chinook stocks through a captive broodstock program. Information on the number of juveniles received into the program is maintained and summarized by year. The production of prespawning adults transferred to Tribal Facilities for spawning is also annually summarized.
