In 1966, congress authorized the Warm Springs National Fish Hatchery to stock salmon and trout within the Confederated Tribes of the Warm Springs Reservation of Oregon reservation to increase tribal harvest opportunities. The current focus of the Warm Springs National Fish Hatchery is to produce spring Chinook Salmon for tribal harvest in the Deschutes and Columbia River and for on-reservation distribution to tribal members. The facility is managed as an integrated hatchery program to minimize genetic divergence between Warm Springs River hatchery and wild stocks. The Columbia River Fish and Wildlife Conservation Office conducts monitoring and evaluation of this hatchery program. This report summarizes broodstock broodstock
The reproductively mature adults in a population that breed (or spawn) and produce more individuals (offspring or progeny).
Learn more about broodstock need, juvenile production levels, and marking and tagging information for the past ten years. After juvenile release, the detection rates at Bonneville Dam, juvenile survival, adult returns, smolt-to-adult survival rates inferred from coded-wire tag recoveries, and adult age structures are reported. Special studies and recommendations for future studies supported by U.S. Fish and Wildlife Service funds are also discussed
