| Summary: | During the summer of 2019, Alaska Department of Fish and Game Division of Sport Fish staff conducted a rapid systematic inventory of anadromous fish distribution and associated aquatic and riparian habitat in select drainages of the upper Yukon River and Tanana River. Target streams will be selected to fill gaps in coverage of the State of Alaska's Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes (AWC) for freshwater habitats expected to support anadromous fish populations likely to be impacted by human activities. Two crews sampled standardized target stream reaches using electrofishers with sufficient effort to collect all species (perhaps with the exception of rare species) of the extant fish community. At each sampling site, crews documented standard aquatic and riparian habitat characteristics. For each water body in which anadromous fish are observed, nominations to the AWC were submitted. One hundred sites were surveyed during this study period, a slightly ... : Following ADF&G's AFFI protocols, two crews, each with two members, will simultaneously sample fish communities in selected study stream reaches for approximately 20 days during the summer of 2019. Target survey sites will include wadeable headwater streams sampled with a backpack electrofisher and un-wadeable streams (including mainstem rivers) sampled with a raft mounted electrofisher. Two helicopters will provide access to the stream study sites for headwater and cataraft crews. Sites within the study area that have the highest potential for habitat degradation will be identified through consultation with the ADF&G Division of Habitat and will be given a higher sampling priority. The number of headwater streams in the study area will exceed the project’s limited sampling effort capacity; therefore, a subset of mapped streams, comprising the longest stream segments not currently listed in the AWC, will be selected as target streams. The headwater team will sample approximately six to eight ... |
