The analysis of cytogenetic anomalies frequency in peripheral blood cells and bone marrow cells at three groups carp was carry out. Groups carp belong to various intra-breed types (scale carp, few-scale carp, frame carp), which breeding in economy “Nivka” of the Institute of Fish- eries of the UAAS. Not observed intra-group and inter-group differences to frequencies of cells with micronuclei and binuclear cells. However there is wide individual variability to number of chromosomes in bone marrow cells. Thus, for fish the frequencies of cells with micronuclei and binuclear cells are objective character of cytogenetic stability.

The analysis of the development state and prospects of “Lviv oblribokombinat” fish-farming is conducted. It is shown, that rise of pond fish-productivity , improvement of fish gravimetric standards and its quality it is possible by during realization of industry intensification measures only. It is shown that commodity two-year carps weighing 0.8–1.0 kg can be got having of finger- lings weighing 59 grammes.

After treatment of carp, ill оn aeromonosis, ву bringing in water preparation “Vitane”, the significant higher level of total protein in blood serum and the higner activity of antioxidant en- zymes (SOD, glutathione peroxidase, katalase) in erythrocytes, than in ill control fishes without treatment, were revealed. After treatment of ill carp perorally ву preparation of vitane, the greater content of peroxidative oxidation products in blood plasma and the higher activity of antioxidant enzymes were discovered, in comparison with the fishes of control group.

Authors: PRINCIPLES OF PIKEPERCH HARVEST REGULATION OF THE KAKHOVKA RESERVOIR

There have been analyzed biological parameters of pikeperch in commercial and control catches on the Kakhovka reservoir. We showed unrational distribution of commercial fishery load by age groups, which affects mortality parameters and significantly decreases expected commercial return from each generation. Measures of pikeperch harvest optimization were proposed.

There have been presented quantitative and qualitative parameters of phyto- and zooplankton of the Kremenchuk reservoir at current time. With the aid of regression analysis, we found statisti- cally significant dependencies between vegetation level of different size groups of phytoplankton and quantitative and qualitative composition of major systematic zooplankton groups as well as among its dominant organisms.

There are presented data of 2005–2007, which characterize biological state of bream (Abramis brama L.) and roach (Rutilus rutilus L.) populations of the Dneprodzerzhinsk reservoir.
