A
quantitative framework for the analysis of habitat and hatchery practices
on Paci€c salmon
Abstract |
| We developed
a model to capture the interaction of two factors (habitat and hatchery
indicators) on salmon abundance, and provide a framework for evaluating
alternative restoration actions for salmon in the northwestern United
States, assuming speci€c ocean conditions and harvest rates. We modeled
different hypothetical coho salmon population trajectories in Issaquah
creek (King County, western Washington, USA) as a function of land-use
change and hatchery supplementation. The model can be tailored to
address individual problems, areas and questions. |
