Movements of Stream-Resident and Anadromous Arctic Char ( Salvelinus alpinus ) in a Perennial Spring on the Canning River, Alaska
Perennial springs in arctic drainages are used extensively by freshwater-resident and anadromous segments of Arctic char (Salvelinus alpinus) populations. Movements of these fish were monitored in a small spring on the Canning River from May 23 to October 7, 1973, dates approximating spring breakup...
