- Abstract
Twenty-two fish species associated with bedrock and gravel were sampled in the subtidal zone of Port Daniel Bay in the Baie des Chaleurs,Gulf of St. Lawrence. These substrata supported different flora and invertebrates. Although different numbers of fish within species werecollected over the two substrata, species diversity measured as species richness and heterogeneity of species, and the number and quantity of prey items in stomach contents were similar. Therefore, a singlefish community appeared to occur in the subtidal zone. The logarithmic series described the species heterogeneity, suggesting a mature community. Most fishes preyed on echinoderms, in contrast to studies further south, when the same species primarily preyed on crustaceans.
