examination of fine-scale spatial-temporal overlap and segregation between two closely related congeners gadus morhua and gadus ogac in coastal newfoundland.the spatial and temporal movement patterns of sympatric juvenile atlantic cod gadus morhua and greenland cod gadus ogac were studied using high-resolution radio-acoustic positioning in a coastal area of newfoundland during the summers of 2009 and 2010. a total of 20 fish (10 g. ogac and 10 g. morhua) were equipped with acoustic transmitters and monitored for periods up to 23 days. most fishes showed high site fidelity with mean residence times of 12·4 (g. morhua) and 14·4 days (g. ogac). a few i ...201425041096
