Abstract

Cosmopolitan freshwater jellyfish Craspedacusta sowerbii L a n k e s t e r 1880 (Cnidaria, Hydrozoa) was recorded for the first time in the lake Velika peskara near Zrenjanin (Serbia and Montenegro) in summer 1998. A natural population of C. sowerbii from the lake Velika peskara was analyzed for genetic variability at 9 enzyme loci (Gpi, Hk, Idh-1, Idh-2, Me, Mdh-1 Mdh-2, Pgm and Sod) by polyacrylamide gel electrophoresis. A zymogram indicated that population was monomorphic at all analyzed loci.Kosmopolitska slatkovodna meduza Craspedacusta sowerbii L a n k e s t e r 1880 (Cnidaria, Hydrozoa) registrovana je prvi put u vestackom jezeru Velika peskara kod Zrenjanina (Srbija i Crna Gora) u leto 1998. Prirodna populacija vrste C. sowerbii iz jezera Velika peskara proucena je metodom poliakrilamid gel elektroforeze i pritom je analizirana geneticka varijabilnost 9 enzimskih lokusa (Gpi, Hk, Idh-1, Idh-2, Me, Mdh-1, Mdh-2, Pgm i Sod). Tumacenjem zimograma utvrdjena je monomorfnost svih analiziranih lokusa populacije. Odsustvo geneticke varijabilnosti u analiziranoj populaciji verovatno je rezultat pasivne disperzije i smene polnog i bespolnog razmnozavanja vrste C. sowerbii, te je moguce da su geneticki identicne jedinke prva generacija meduza nastalih pupljenjem polipa koji su nedavno introdukovani u jezero Velika peskara.
