A stochastic life-cycle model investigation of the potential benefits of a conservation hatchery program for supplementing Oregon Coast coho (Oncorhynchus kisutch)

A stochastic life-cycle model investigation of the potential benefits of a conservation hatchery program for supplementing Oregon Coast coho (Oncorhynchus kisutch), Gretchen R. Oosterhout, PhD and Charles W. Huntington, 2003, 47 pp., $10.

Independent researchers Gretchen Oosterhout and Charles Huntington adapted an existing life-cycle model for coho salmon to enable computer simulation of interactions between wild and hatchery fish in a river basin. The new model examined the potential effects of proposed state-of-the-art conservation hatchery designs intended to reduce negative effects on wild fish while boosting failing returns of salmon.The study underscores that recovery of dwindling salmon runs depends not on fish hatcheries, but squarely on the protection and restoration of freshwater habitat.
