Fish Stocking and Schedules

Fish and Game stock over 30-million fish from its hatcheries into rivers, lowland lakes, reservoirs and mountain lakes every year.

Stocked fish include fry, fingerlings, and catchable sized fish from 18 species and 16 strains. Most of the resident hatchery fish released are rainbow trout and kokanee salmon. Other fish raised and planted by Idaho’s hatcheries include walleye, channel catfish, and tiger muskie. Hatchery raised trout, especially the catchable size of 10-12 inches, are stocked where they are likely to be caught.

Current Stocking Schedule

Catchable fish are stocked in the Spring, Summer and early Fall at many ponds and lakes throughout the state. Check these regional fishing report links to see if fish have been stocked in your area.
