There has been studied the effect of water content on changes of pH and gas regime of spawn- ing areas of phytophilous fish by the example of the Kremenchuk reservoir. It was found that in floodplain zones of the reservoir, the highest effect on changes of water pH and temperature is caused by annual water content. In channel parts, the given dependencies are observed between water temperature and water content. It was shown for the first time a positive effect of specific concentration of free carbon dioxide on viability of eggs of phytophilous fish.

Using the Dneprodzerzhinsk reservoir as an example, there have been determined basic indices, which characterized linear and weight growth of bream. There has been analyzed the relationship between the weight growth rate and commercial catches. There has been assessed the role of indi- vidual weight indices in the bream population ichthyomass formation and its commercial stock.

The possibilities of passive catch plastic traps “AST” using for the checking of effectiveness of grass carp larvae breeding up in spawning and feeding ponds were established. This method allows to check in the same time the growth intensity and survival of larvae and to control the stage of feeding base (zooplankton) in the ponds.

According to the results of two variants of wintering interbreed crosses obtained governmental at the mirror and scaly lines tremlyanskogo carp, the comparative characteristic of survival and loss of body weight of yearlings different origin. As a result, a comprehensive assessment established the most winter-hardy of the group and individual crosses.

There are presented study results on activity of superoxide mutase, catalase and glutathione peroxidase as well as the content of malone dialdehyde and dien conjugates in liver, blood, myo- cardium, muscles and gills of scaled and framed carps of Antoninsky-Zozulenets intrabreeding type. High activity of antioxidant enzymes of tissues of framed carp is caused by metabolism processes intensity.
