• 2004-06 - Hatchery supplementation winds down as part of recovery planning.
• 2012-17 - Populations rebound with reduction of hatchery production and curtailment of harvest

Notes

• File:Tuohy et al. 2018 chum non-natal habitat use.pdf - provides a summary and assessment of nearshore use differentiating between summer and fall chum.
  • Summer chum show high use of embayment habitats, as much as in river deltas
  • Prioritizing restoration sites in proximity to natal streams may not provide greater benefit for summer chum in Hood Canal, given rapid distribution and broad use of nearshore habitat.
