Fidelity of Anadromous Arctic Char ( Salvelinus alpinus) to Nauyuk Lake, N.W.T., Canada
The estimated fidelity of anadromous Arctic char (Salvelinus alpinus) returning to Nauyuk Lake from 1974 to 1978 was low (53%). Seven percent of the fish were absent for 1 or 2 yr before returning. Fidelity was also size dependant. Intermediate-sized fish (35–65 cm) had the highest estimated fidelit...
