Studies on diet of vendace from the Maróz Lake were carried out to determine sea- sonal changes in food composition in relation to changes of zooplankton food resources in the environment. Fish samples, were collected once a month from April to November in the years 1994–1996. A total of 409 alimentary tracts were analyzed. Simultane- ously, crustacean zooplankton samples were collected to assess food abundance. The occurrence of Cladocera and Copepoda in zooplankton samples from the Maróz Lake. Food composition in the gut of vendace did not correspond with zooplankton abun- dance in the water. Due to considerable oxygen de fi ciency in the Maróz Lake (recorded in water layer 4 m below the surface), especially in June, it may be presumed that sublit- toral or even littoral was the bottom zone accessible for vendace, what, in turn, seems to be indicated by the presence of detritus, algae and macrophytes debris in food of the considered fish species.
