Abstract
We possess little information on diet of the pike (Esox lucius L.) in nearly natural water habitats in the Balkans. Between 2006 and 2010, 528 pike were captured at 20 locations in three different water habitats. The capture of pike was done with an angling system a minimum of four times a month. Pike were mainly caught in autumn with the highest number in october. Furthermore, we also found that feeding intensity was highest in autumn. Altogether 15 prey fish species were recorded in pike stomachs. The most frequent prey fish was the Crucian Carp (Carassius auratus gibelio), followed by the Common roach (Rutilus rutilus) and Common Bleak (Alburnus alburnus). In conclusion, species composition of prey fish and the proportion of vertebrate and invertebrate prey mainly differed from other studies probably due to different geographical areas.
