The use and selectivity of small-meshed gill nets at Brooks Lake, Alaska
Heard WR. 1962. The use and selectivity of small-meshed gill nets at Brooks Lake, Alaska. Transactions of the American Fisheries Society. 91(3):263-268
Fine-thread gill nets with meshes of 3/8-, 1/2-, 3/4-, 7/8-, and 1-inch (stretched measure) were used to sample lake-dwelling juvenile sockeye salmon (Oncorhynchus nerka) and associated small fishes in Brooks Lake, Alaska. Thirteen of 20 species known to occur in the lake were sampled with the small meshes. Sockeye salmon, Alaska blackfish (Dallia pectoralis), threespine stickleback (Gasterosteus aculeatus), ninespine stickleback (Pungitius pungitius) and sculpins (Cottus spp.) less than 50 millimeters in length were sampled. Different selectivity patterns were shown by different species in various mesh sizes. Meshes smaller than 1 inch had low catch efficiencies, although these meshes were useful for qualitative assessment of small fishes.
