Freshwater Fish Inventory of the Alagnak Watershed, Alagnak Wild River, Southwest Alaska Inventory and Monitoring Network
Miller JL. 2003. Freshwater Fish Inventory of the Alagnak Watershed, Alagnak Wild River, Southwest Alaska Inventory and Monitoring Network
A freshwater fish inventory was conducted from March through August, 2002 in the Alagnak Watershed. The objectives of the inventory were (1) to document species that were expected yet undocumented and (2) to provide initial descriptions of the distributions, abundance, and biologic characteristics of these species. Minnow traps, minnow seines, beach seines, snorkel gear, hand nets, fyke nets, tow nets, gill nets, hook-and-line, and a gastric lavage were used to sample fish. River, lake, pond, and stream habitats were sampled. Nine of 14 expected but undocumented species were captured or observed: Alaska blackfish (Dallia pectoralis), Arctic lamprey (Lampetra japonica), burbot (Lota lota), coastrange sculpin (Cottus aleuticus), ninespine stickleback (Pungitius pungitius), northern pike (Esox lucius), round whitefish (Prosopium ylindraceum), slimy sculpin (Cottus cognatus), and threespine stickleback (Gasterosteus aculeatus). The fish community of the Alagnak Watershed appears to have fewer species (lower species richness) than the adjacent Naknek and Kvichak systems.
