Matrices of co-occurrences of fish species on the Scotian Shelf and in the Bay of Fundy

The results of annual groundfish research trawling surveys of the Scotian Shelf and Bay of Fundy in the summers of 1970-79 and in spring, summer and autumn 1980-84 provide numbers of co-occurrences in the catches of the principal fish species of the area. These data are presented as matrices by sub-area and season. Original numbers of co-occurrences were grouped and considered for production of graphic matrices for detailed analyses. The effect of change of species order in the matrices by systematic group and by order of preference by bottom type, depth and site type was examined and depth selected as the criterion giving the best resolution of species assemblages. Alternative means of considering co-occurrences are presented including matrices of actual numbers, graphic matrices of standardized number, matrices of percentage co-occurrences of each species in the catches of others, tables of co-occurrence indices.
