Fisheries investigations on the Kandik, Charley, Nation, and Tatonduk rivers, Yukon-Charley Rivers National Preserve, 1987 and 1988
Daum DW. 1994. Fisheries investigations on the Kandik, Charley, Nation, and Tatonduk rivers, Yukon-Charley Rivers National Preserve, 1987 and 1988. Alaska Fisheries Technical Report. 23. US Fish and Wildlife Service. Fishery Resource Office. Fairbanks, AK
Baseline fisheries investigations done during the summer and fall of 1987 and 1988 are presented. These studies were designed to document 1) the distribution, relative abundance, population characteristics, and habitat use for anadromous and resident fish; 2) spawning areas and run timing for chinook, coho, and chum salmon; and 3) aquatic macroinvertebrate density, biomass, diversity, and composition. Fifteen fish species were found in the four river drainages. Arctic grayling, slimy sculpin, round whitefish, burbot, and longnose suckers were the most common residents of upstream environments. Areas at or near the confluence with the Yukon River had the greatest fish diversity. No coho salmon or broad whitefish were caught: coho probably do not occur (references to them by local inhabitants are probably attributable to the custom of selling chum salmon as silvers) and broad whitefish probably do occur (but were not caught due to seasonal differences between sampling dates and species distribution). The Nation and Tatonduk rivers had the highest water quality values and aquatic macroinvertebrate density and biomass measurements.
