Operational Plan for the Restoration of Diadromous Fishes to the ...

3. Results (hypotheses) with linked management options should be stated a
priori, and assessments should be designed to address these.
4. Adaptive management should occur at the project and program scales. That
is, how successful was the project, and how does this level of success fit in
with the overall program?
5. Assessment of results and subsequent management actions should
emphasize potential to restore naturally reproducing populations.
Table 6. Adaptive management actions related to actions that increase adult
escapement, based on expected YOY and parr abundances and size
distributions and two redds/female.
