Small Lake Sockeye Hydroacoustic Surveys, 2010
Small lake sockeye populations in the Skeena watershed have been severely depressed for decades. In the past, monitoring the status of small lake sockeye has proven difficult because of remote locations and the poor visibility of glacially fed lakes. These studies employ a novel, cost-effective method for enumerating sockeye populations in small, turbid lakes – a dual-beam data-recording echosounder with concurrent trawl and gillnet sampling. The Skeena Fisheries Commission surveyed fall sockeye fry in eight lakes in 2010 (Johanson, Stephens, Minerva, McDonell, Sustut, Swan, Lakelse, and Bulkley).
