Available in PDF, EPUB and Kindle. Book excerpt: From 2009 to 2012 a series of memos were written by Alaska Department of Fish and Game staff in Kodiak discussing reasons for the low runs of sockeye salmon to Karluk Lake that began in 2008 and persisted through 2011. Historical trends in escapement, run size, limnology, climate, and trends in fish size, age, and growth for Karluk Lake sockeye salmon were investigated. The authors emphasized the role that the small body size and low condition of outmigrating smolt in 2005 and especially 2006 likely played in determining marine survival and subsequent run strength. Major factors thought to cause the small size at smolt outmigration were decline of zooplankton biomass, decline in body size of the preferred sockeye salmon food source (Bosmina), decrease in Karluk Lake seasonal water temperatures, and overescapement. The suggested mechanism was that large escapements and favorable spawning conditions produced large numbers of fry for numerous years, which eventually overgrazed and reduced the number of zooplankton available to fry. Sockeye salmon fry then experienced slow growth and increased mortality, which led to poor condition (and fewer) smolts. Furthermore, it was predicted that Karluk would likely be depressed for a period of 3-5 years beginning in 2008. Data thus far remain consistent with the original hypothesis; however, the outlook appears to be one in which runs improve in 2012.

Download or read book Karluk Lake Sockeye Salmon Smolt Sampling Project, 2011 to 2013 written by M. Birch Foster and published by . This book was released on 2017 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
