Depth, Temperature and Salinity Preferences of Common Fishes of the Scotian Shelf

Data from research bottom-trawl surveys of the Scotian Shelf and the Bay of Fundy in the 1970-79 period are analyzed to present total and preferred ranges and means of depth, temperature and salinity for 31 common fishes.Geographical variation in relation to preferences and to fish distributions is examined for selected groups of fishes.Niche diversity is exemplified in groups of related species.
