Basinwide Supplementation Evaluation Project: 2018 Annual Progress Report

Jun 28, 2021


This report summarizes activities for calendar year 2018 performed as part of the multi-year project organized under the eight project objectives. The primary objective of the Project involves monitoring and evaluation of tribal hatchery programs to assess: a) critical uncertainties related to effects of hatchery supplementation on productivity of depressed natural anadromous fish populations, and b) productivity trends in new natural populations established through reintroduction of out-of-basin origin fish (both of hatchery origin or natural origin) in subbasins where the indigenous population had been extirpated.
