Abstract
Experimental gill-netting and tagging programs were undertaken in the Eastmain and La Grande rivers of James Bay to determine the migratory patterns of anadromous cisco (Coregonus artedii) and lake whitefish (C. clupeaformis). Cisco and whitefish were found to differ in the distribution of juveniles during summer, in the upriver migration of mature fish, and in the selection of overwintering sites. Models are presented to illustrate the general life cycles of anadromous cisco and lake whitefish in James Bay.
