Pike’s food from a river and a carp pond
Summary.

Alimentary tracts of 202 pikes originating from two different biotopes, a river and a carp pond, were analysed. Both in the river and the pond, in pike food, there dominated roach and perch. As far as the mass of pike’s preys is concerned, among pikes originating from the river, there dominated crucian carp (57.9%), while in the mass originating from the pond, perch (53.9%) was the dominant. Weight coefficient of food differentiation between the studied habitats differed only slightly. A similar situation was found in case of the index indicating the filling of alimentary tract. A significant difference occurred in the values of the differentiation of food regarding the quantity. For pikes from the river, the coefficient value amounted to 4.24 and for pikes from the pond, it was 2.24. Studies have confirmed that regardless of the biotope in which pike occurred, roach and perch dominated in the food. On the other hand, the place of living exerted a significant influence on the quantitative coefficient of food differentiation.
