We found that C. cun>ispinum was the dominant amphipod at each sampling site; the dominance was more expressed on the macrophyte stands than on the surface of the stones (Fig. 1). Moreover, D. haemobaphes and D. villosus were present in the samples. There was no significant difference between the amphipod population of the two macrophytes investigated. In August 1986 we collected amphipod samples from the dominant macrophyte of 10 shoreline stands around Lake Balaton. On nine stands P. perfoliatus was the dominant submerged macrophyte; on the stand near Keszthely M. spicatum dominated. C. cunispinum was the dominant amphipod on each stand; their proportion exceeded 90% of the amphipods. D. haemobaphes and D. villosus also occurred in the samples. The abundance of amphipods at Keszthely was much
