Book Description
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 2011. 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 sockeye salmon forecast.

Book Description
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.
Chignik River System Sockeye Salmon Smolt Sampling Project Operational Plan, 2020–2022

Pages : 33
Book Description
This operational plan describes the procedures for the sockeye salmon Oncorhynchus nerka smolt sampling project conducted by the Alaska Department of Fish and Game (ADF&G) in the Chignik River system. The project goal is to evaluate and document size and abundance trends of sockeye salmon smolt in the Chignik River system to understand rearing capacity and habitat use. The research is designed to assess age structure, fish body condition, and provide additional context for the adult sockeye salmon forecast. Age structure of the population will be estimated from scales of sockeye salmon smolt collected using a beach seine. Juvenile salmon habitat use will be examined by beach seining in near-shore marine environment. Findings from this project are vital for understanding effects of the commercial fishery and environmental changes occurring in the Chignik River system on the sockeye salmon population.

Book Description
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 2019 and 2020. The research was designed to assess fish body condition and document relative abundance and timing in the Chignik watershed. Sockeye salmon smolt were captured using a beach seine in Chignik Lagoon. In 2019, 1,175 usable samples were collected. Of these, 504 (43.0%) were freshwater-age-0; 645 (54.9%) were freshwater-age-1; and 26 (2.2%) were freshwater-age-2 smolt. In 2020, 1,663 usable samples were collected. Of these, 56 (3.4%) were freshwater-age-0; 1,569 (94.3%) were freshwater-age-1; and 38 (2.3%) were freshwater-age-2 smolt. Sockeye smolt were of above-average body condition in 2019 whereas in 2020, smolt were about average compared to historical data.
