AB The interactions between bullhead (Cottus gobio), stone louch (Borbutulu bnrbatulu) and gudgeon (Gobio gobio) and subsequentlytheir influence on the exclusion capacity of these species were examined in laboratory experiments. When a combination of gravel,sand and sand plus shelters substrate types were offered, the three species selected sheltered substrates. This preference was strongerwhen the three species wcre together rather than when in allopatry. None of the species showed any preference to coexist with anotherunder sheltered positions. When only one specics occupied a sheltered position it was alone, without any other conspecific. Dispersalpatterns differed bctween species but during this process there was no evidence of any species association. This study highlights a verylimited interspecific interaction between bullhead, stone loach and gudgeon, and shows that intiaspccific exclusion in these specieswas much more important than the interspecific one.
