註釋From July 20-August 5th, 2020 and opportunistic dates in September or October, the Alaska Department of Fish and Game, Division of Sport Fish, will inventory stream fish assemblages and associated habitats in a 82,645 km2 study area selected around the upper Yukon, Tanana, and Copper rivers. Staff identified 255 potential sample sites on small and intermediate sized stream of which we anticipate sampling at least 100 headwater streams and 20 intermediate un-wadeable streams. At each site, prior to electrofishing crews will collect data describing location, water quality, stream characteristics, aquatic habitat, and riparian vegetation. Fish will be collected primarily using backpack and raft mounted electrofishing equipment, and hook-and-line, minnow traps, and aerial observations will be used as supplemental sampling methods. Anadromous fish assemblage data collected will be used to nominate waters to the State of Alaska's Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes (Anadromous Waters Catalog, AWC), or to update fish life stage information for waters already listed in the AWC. All sampling data will be available via the ADF & G Alaska Freshwater Fish Inventory (AFFI) online mapping application.
