Explanation of Hatchery Returns

Hatcheries trap salmon that will be spawned to provide future salmon. Known as “Broodstock” these fish are collected from all returning fish, not just from early or late arrivals.  Broodstock goals listed here are the target number of adult fish needed to produce future salmon releases. 

Broodstock are adult fish that will be spawned to provide future salmon. Broodstock is collected from all returning fish, not just from early or late arrivals.

The trapped fish may be:

  1. released back into ongoing fisheries,
  2. provided to Indian tribes for subsistence needs under harvest sharing agreements, 

  3. ‚Äčdistributed to food banks,

  4. released to spawn naturally in the wild. 

There are still wild (native) Chinook salmon in Idaho that continue to survive migration despite increasing obstacles. They have an intact adipose fin which identifies them from hatchery fish. 

Idaho Fish and Game manages six hatchery stocks of Chinook salmon. Each hatchery has a broodstock goal. Dworshak, Clearwater and Rapid River hatcheries originated from the same genetic stock so managers may use broodstock from one facility to make up for a shortfall at another.

Chinook salmon from Pahsimeroi, McCall and Sawtooth are unique to their river systems. These facilities will not use fish from another hatchery to meet their broodstock goals.
