Fishes of the Thomsen River, Banks Island, Northwest Territories / by S.A. Stephenson. : Fs97-4/2944E-PDF

"The Thomsen River on northern Banks Island has been described as the most northerly multi-species river in North America (Zoltai et al. 1980). Due to its' remote location and near pristine state, it is a unique area to examine riverine fish stocks and their interactions. Rivers north of the Thomsen on other Arctic islands [e.g., Melville and Bathurst islands (Stewart and Bernier 1982)] possess a fish assemblage of Fourhorn Sculpin (Myoxocephalus quadricornis) and Arctic Char or only Arctic Char. At least three species, Lake Trout (Salvelinus namaycush), Least Cisco (Coregonus sardinella) and Ninespine Stickleback (Pungitius pungitius), reach their known northern limit of distribution in the Thomsen River. … In this manuscript I: (1) summarise historic fish capture information for the Thomsen River watershed and Banks Island in general (2) present new information on fish species collected during survey work in the Thomsen River during 2000 and 2001, (3) briefly present information on the zoogeography of fishes of the Thomsen River and Banks Island in general, and, (4) make recommendations for additional research"--Introduction, page 1.
