The natural diet of five cyprinid fish species

The investigation of the ichthyofauna in the upper part of the Croatian section of the Sava river, the so called barbel zone, showed that very frequent and quite numerous fish species were chub (Leuciscus cephalus (L., 1758)), bleak (Alburnus alburnus (L., 1758)), spirlin (Alburnoides bipunctatus (Bloch, 1782)), barbel (Barbus barbus (L., 1758)) and stream barbel (Barbus meridionalis petenyi Heckel, 1847). There are very few published papers on the biology of these fish species, and even less on their natural feeding in the open waters. Although these fish species economically less important, is play an important role in the open waters ecological niche. One of the most important factors for the ecological niche is food web. Therefore, the purpose of this paper was to revise the research and written documentation collected on the feeding of chub, bleak, spirlin, barbel and stream barbel in Croatia and in Europe. More important results on recent research done for each fish species in various waters in Europe are also presented in this paper.
