Seasonal and interannual variation in fish assemblages of northern temperate rocky subtidal habitats.
Fish assemblages on two inshore rocky subtidal sites on the west coast of Scotland, were studied using diver visual surveys on a monthly basis between September 1995 and December 1999. A total of 17 689 fishes and 26 species were recorded from the two sites, Saulmore Point (056degrees27'N; 005d...
