The 2013 Karluk Sockeye Salmon Smolt Enumeration project marked the second consecutive year of sockeye salmon smolt enumeration on the Karluk River, after a five year hiatus from 2007-2011. This report provides the daily and cumulative smolt outmigration estimates as well as biometric and age composition information, and when possible, comparisons with historical data. The research was designed to estimate smolt population size and age structure, assess fish body condition, and collect samples from the outmigrating smolt population for isotopic composition. The abundance of sockeye salmon smolt was estimated using Canadian fan traps and mark-recapture techniques.

The 2012 Karluk Sockeye Salmon Smolt Enumeration project was the revitalization of smolt enumeration on the Karluk River, which was discontinued in 2006. This report provides the daily and cumulative smolt outmigration estimates as well as biometric and age composition information, and when possible, comparisons with historical data. The research was designed to estimate smolt population size and age structure, assess fish body condition, and collect samples from the outmigrating smolt population for isotopic composition.

The 2014 Karluk Sockeye Salmon Smolt Enumeration project marked the third consecutive year of documenting the smolt outmigration from Karluk Lake since 2006. This report provides the daily and cumulative smolt outmigration estimates as well as biometric, age, and genetic stock composition information. Limnological data collected from Karluk Lake by the Kodiak Regional Aquaculture Association are also presented. The abundance of sockeye salmon smolt was estimated using a Canadian fan trap and mark-recapture techniques. In 2014, a total of 811,255 sockeye salmon smolt were estimated to pass downstream of the trap between May 13 and July 2. The majority of smolt sampled were freshwater-age-2 fish (70%), and average length and weight of each age class were some of the largest in the historical data series. The majority (78%) of outmigrating smolt belonged to the late-run stock, which were mostly freshwater-age-2 fish. The average weighted zooplankton biomass of 2,687 mg/m2 in 2014 suggests juvenile sockeye salmon in Karluk Lake reared in a healthy nursery environment prior to their outmigration.

Karluk Lake is located on the southwest side of Kodiak Island and supports the largest sockeye salmon (Oncorhynchus nerka) run in the Kodiak Management Area. Sockeye salmon smolt studies have been conducted sporadically on Karluk Lake since the 1920s. This project reinstituted a Karluk Lake sockeye salmon smolt program to estimate the size and condition of outmigrating smolt; in addition, individual smolt were collected on an annual basis for stable isotope analysis. Sockeye salmon smolt outmigrating from Karluk Lake were sampled for size and condition from 2011 to 2013. Annually, a total of three strata samples (early, middle, late), with a goal of 280 fish per stratum, were collected and used to quantify the average length, weight, and condition of the outmigration. Whole fish samples were frozen for isotope analysis. Modeling experiments using body size as a parameter in a total adult run forecasting were conducted. Results demonstrated no statistically significant differences in body size estimates between strata within years; however, 2013 body size was significantly larger than 2011 and 2012 and the largest recorded in the history of the project time series. Isotope analysis yielded variable results over years but, overall, demonstrated isotopic signatures differing between systems, years, outmigration timing, and size. The forecast model performed well, albeit under a limited range of climate variability as well as fairly robust escapements, but it is potentially suitable for forecasting future salmon returns.

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 2013. 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.
