General Program Description

Name of Hatchery

Trinity River Hatchery (TRH).

Species and Population (or Stock) Under Propagation, and Environmental Species Act (ESA) Status

Trinity River coho salmon (Oncorhynchus kisutch) are included in the Southern Oregon/Northern California Coasts (SONCC) Evolutionary Significant Unit (ESU). On May 6, 1997, the Federal Register (62 FR 24588) declared a threatened status for coho salmon in the SONCC. On June 28, 2005, the Federal Register (70 FR 79202) promulgated final listing determinations and 4(d) protective regulations, which included Trinity River Hatchery (TRH) coho salmon as a part of the SONCC, as well as amended 4(d) protective regulations to provide for management of artificial propagation programs and consistency with the conservation needs of the ESA-listed SONCC ESU.

The California Fish and Game Commission listed coho salmon as a threatened species pursuant to the California Endangered Species Act within the California portion of the SONCC on March 30, 2005.
