| Abstract/Description or Keywords |
Skeena Fisheries Commission (SFC) conducted hydroacoustic surveys at five sockeye rearing lakes in the Skeena Watershed. Shallow and glacial turbid lakes were selected in order to determine whether a horizontally oriented transducer in conjuction with conventional down-looking hydroacoustic methodolgy would effectively sample the top layers of lakes where fish are thought to be surface oriented. Surveys were conducted at Atna, Azuklotz, Kalum, Motase, and Slamgeesh Lakes. The horizontal transducer proved to be most effective at Atna, Azuklotz and Motase lakes. Overall fish density ranged from 49 fish/hectare at Atna Lake to 1,041 fish/hectare at Azuklotz lake. |
