Restoration Potential: Recovery will be difficult due to the large number of small coastal streams in which changes in logging and road construction plans would have to be made (Moyle et al. 1989).
Management Requirements: Hatcheries contribute to much of production (Hassler 1987). Meffe (1992) gave reasons why the hatchery approach to recovery ultimately will fail, and he emphasized that overharvest and habitat destruction need to be addressed in a major landscape-level effort. See Thomas et al. (1993) for information on habitat management for this and other at-risk fish species in the Pacific Northwest.
To regulate fishery for optimum yield, California, Washington, and Oregon have limited entry of new fishing boats into fleet and have instituted catch quotas (Hassler 1987).
Stocks transplanted to non-native streams exhibit reduced survival (see Williams et al. 1992).
Allendorf et al. (1997) proposed criteria for prioritizing Pacific salmon stocks for conservation; data limitations introduce subjectivity into the process, so expert judgment and peer review should be incorporated into the process.
Biological Research Needs: Determine genetic variation among wild populations in different streams.
