Life History of Two Isolated Populations of Arctic Char ( Salvelinus alpinus ) in Spring-Fed Tributaries of the Canning River, Alaska
Two isolated populations of Arctic char (Salvelinus alpinus) in spring-fed tributaries of the Canning River, Alaska, had meristic characters that corresponded to those of the Western Arctic–Bering Sea form of Arctic char. The two populations demonstrated slight differences in growth rates, age at ma...
