The article examines the diet of pikeperch (Sander lucioperca (L.)) of the Kaniv reservoir during spring period. According to obtained data, its diet included 17 food components, among which 14 fish species. The basis of its diet by the frequency of occurrence consisted perch (2.2%), roach (16.9%), monkey goby (14.6%) and own juveniles (10.0%). By the relative weight of food objects in the gut content, the dominated species were roach (42.9%) followed by perch (25.8%) and own juveniles (16.2%).

The main task of the study was identifying differences in growth parameters of individual trout hatchlings handled alone and in a group. Hatchlings were divided into two groups. The first group of hatchlings of various body length and weight was placed to 25 aquaria, a single fish in each. Another group was placed in three equal aquaria. Body weight and mortality have been recorded. Being in a group was found to compensate effects of stress factors. Isolation is a stress for trout hatchlings; combined with other stress factors, it can be a cause of death. These results indicate close connection between theories of group effect and stress.

Effect of using the new anti-bacterial drug floron on the one years carps with swimming bladder inflammation was showed. Studied impact of the disease on physiological biochemical indicators fish. Sensitivity of micro flora to the floron, selected from the sick fish was set. Floron has positive impact on sick fish when its use at dose 0.5 g of the drug on 100 kg of body weight fish.
