The feeding relationships of a small demersal fish community in the western Irish Sea

The feeding relationships of seasonal and resident fishes captured on a sandy substratum in the lrish Sea, in June and in September, were investigated. Stomach content analysis of the 17 species examined indicated four main feeding tvpes in the June sample and three in the September sample. The majority of the species analysed in both June and September showed the same food preferences in both months. Most of the fish species showed some changes in diet with increasing length (ontogenetic shift) - some became more specialized and others favoured more varied diet. There was no evidence of competition between specialist feeders within size groups.
