Skeena Fisheries Commission (SFC) conducted hydroacoustic surveys in two sockeye salmon rearing lakes in the Babine watershed in 2015. Nilkitkwa Lake and the North Arm of Babine Lake are considered to be the primary rearing areas for the progeny of sockeye salmon which spawn in the lower and upper Babine River, respectively. The main objectives of the surveys were to estimate the total abundance and biomass for the sockeye fry populations and the fish species composition of each lake.
