Description

The Umpqua Coho Pedigree Study is an ongoing cooperative research project between the Oregon Department of Fish and Wildlife (ODFW) and Oregon State University (OSU). We investigated several areas of uncertainty about the use of hatcheries to increase the abundance of wild coho populations. There is considerable interest in using hatcheries to speed the recovery of wild populations; however, some literature indicates hatchery programs may pose risks to wild populations. If the risks are substantiated, supplemented hatchery fish could actually impede further recovery of endangered Oregon coast coho salmon populations.
This study traces the reproductive success of three cohorts of single generation hatchery stock (SGHS) and multi-generation hatchery stock (MGHS) through the F2 generation of returning adults. The study also evaluates the difference between fish reared for one year in a hatchery and released as smolts versus fish released shortly after hatching as unfed fry. We employed genetic methods to evaluate reproductive success, choice of mates and risks associated with hatchery programs for each type of stock and release. Molecular DNA methods allow us to track the survival and reproductive success of hatchery supplemented and naturally reproducing coho salmon. In comparing the two hatchery stocks, type of release and naturally reproducing coho, we can evaluate the success or failure of hatchery supplementation programs and measure the risks of population bottlenecks, increased inbreeding, increased genetic load, and loss of genetic variation that are predicted by genetic theory.

Project Benefit

The Umpqua Coho Pedigree Study advances our understanding about using hatcheries as a conservation recovery tool to improve the status of wild coho populations. It will also provide information on genetic risks and population theories.

Key issues addressed by genetic analysis research
The research findings will be used for adaptive management and policy changes that include: 1. Use of SGHS versus MGHS for conservation recovery programs for coastal coho. 2. Use of unfed coho fry versus smolts for conservation recovery programs. 3. Potential genetic risks of using hatchery programs for conservation recovery programs for coastal coho.
