"Demersal research trawl survey data for the Scotian Shelf and Bay of Fundy, were analysed by cluster analysis in order to: define and map the demersal fish assemblages; examine the patterns of diversity of demersal fishes; and explore a simple habitat suitability model for yellowtail flounder. The analysis producing six site groups was selected as the most reasonable and interpretable. Similarly, a clustering level producing six species groups was selected for display. Site group 1 occurs mainly on the eastern Scotian Shelf, but also in the mouth of the Bay of Fundy (main species, American plaice, thorny skate, smooth skate, Vahl's eelpout). Site group 2 occurs mainly on the western shelf in deep water between banks and along the Fundian Channel (main species, spiny dogfish, pollock, cusk, blackbelly rosefish, argentine). Site group 3 occurs mainly on banks and in the head of the Bay of Fundy (main species, haddock, halibut, wolfish, sand lance) Site group 4 occurs primarily in the central Scotian Shelf (main species, red hake, silver hake, angler). Site group 5 is in deep water along the slope of the Laurentian Channel, the outer Scotian Shelf slope and the mouth of the Fundian Channel (main species, common grenadier, longfin hake, redfish). Site group 6 is largely in shallow water in the Bay of Fundy and around Sable Island (main species, longhorn sculpin, sea raven, winter flounder). Depth and temperature were used to predict the occurrence and abundance of yellowtail flounder. Years 1970-1989 were used to develop the model which was used to predict for years 1990-1993. There was significant correlation between predicted and observed values"--Abstract, page iv. Includes abstracts in English and French. Groundfishes Scotian Shelf. Groundfishes Fundy, Bay of.
