Anadromous Fish Predation Strategies, Actions, and Metrics


Predation Strategies
  • Redistribute avian predators
  • Reduce fish predation

Predator control actions: Predator control actions are expected to provide survival improvements to all listed ESUs.
  • The Corps and USFWS are finalizing the Caspian Tern Environmental Impact Statement (EIS). The Corps, BPA, and USFWS and will initiate implementation of the selected alternative.
  • The Corps and BPA are continuing and expanding our research efforts to monitor and evaluate the effects of Caspian tern redistribution on juvenile salmon.
  • The Corps and BPA will initiate studies to investigate the regional double-crested cormorant population and potential management measures to disperse that population.
  • BPA is increasing the reward structure for the Northern Pikeminnow Management Program (NPMP) to achieve further reduction of pikeminnow predation on listed salmon and will also use an incentive-based approach to test site-specific removals of northern pikeminnow and other non-indigenous fish predators.

Predation Metrics
  • Report on the change in annual predation rates and the estimated resulting change in annual juvenile salmonid survival rates.
