✦ Synopsis

Species composition, size distribution, egg number and biomass of different amphipod species on littoral submerged aquatic vegetation (Myriophyllum spicntum and Potamogeton perfoliatus stands) and on the stony shores of Lake Ralaton a t Tihany were estimated in August 1983 and 1985. Three species occurred in the material : Corophium curvispinum, Dikerogammarus hwmobaphes and UiEerognm.maru~s villosus. The bulk was formed by C. curvispinum. The mean number of eggs per female of the t,hree investigated species showcd differences at the different sampling stations and ranged between the following values: C . curvispinum from 3.3 to 8.8, D. haernobnphes from 16.4 to 22.8 a,nd D. villosus from 8.0 to 17.5. The total biomass of amphipods was 1.8 and 3.5 mg dry weightig fresh weight of niacrophytes in 1983 and 1985 respectively, itnd 4.7 mg animal per dm2 stone surface in the st,oiiy lit,t,oral zone in lY83.
