This report describes the results of the sockeye salmon Oncorhynchus nerka smolt monitoring and enumeration project conducted by the Alaska Department of Fish and Game (ADF&G) in the Chignik River system in 2012. The research was designed to estimate smolt population size and age structure, assess fish body condition, describe limnetic habitat conditions and forage base, collect samples for genetic stock identification, and provide data for the Chignik River preseason adult sockeye salmon forecast.

This report describes the results of the sockeye salmon Oncorhynchus nerka smolt monitoring project conducted by the Alaska Department of Fish and Game in the Chignik River system in 2021 and 2022. The research was designed to assess fish body condition and document relative abundance and outmigration timing in the Chignik River watershed. Sockeye salmon smolt were captured using a beach seine in Chignik Lagoon. In 2021, 1,348 ageable scale samples were collected. Of these, 974 (72.3%) were freshwater-age-1 and 370 (27.5%) were freshwater-age-2 smolt. In 2022, 1,378 ageable scale samples were collected. Of these, 752 (54.6%) were freshwater-age-1 and 377 (27.4%) were freshwater-age-2 smolt. Sockeye smolt were of above-average body condition in 2021 and 2022 when compared to historical data.
