Abstract
microps (Kroyer), Gasterosteus aculeatus (L.), Pungitius pungitius (L.) and Anguilla anguilla (L.) were the most common species in the guild and P. microps was overall most numerous. The four species Gobius niger (L.), Gobiusculus flavescens (Fabricius), Platichtys flesus (L.) and Pleuronectes platessa (L.) invaded the guild more temporarily. Food resource overlaps were significantly higher in June/July than in September/October. The species decreased their niche widths to increasing diversity in the guild and to a higher species pair overlap values. The diffuse overlap was higher in June/July than September/October. The differences in overlap values, diffuse overlap, decreased number of species together with the reaction of the niche width of each species and the whole guild may explain that competition for food occurred at least temporarily under the study period.
