There is examined the current biological state of fish populations, which consist the base of commercial harvest in the Kakhovka reservoir. There are analyzed basic trends, which characte- rize the change of age structure of exploited populations and repartition of catches by mesh size in fishing gears. There are assessed dynamics of commercial stocks recruitment and formation of fish base for commercial harvest. There are proposed optimization ways for commercial exploita- tion of the Kakhovka reservoir.

There has been analyzed the current state of roach commercial stock of the Kanev reservoir. With the aid of cohort analysis, there were estimated fishing mortality, possible number, and bio- mass of commercial stock of this species for 2005–2006. There were modelled yields per recruits of silver bream using a Thompson and Bell type model. According to results, the roach commercial stock of the Kanev reservoir is exploited irrationally.

There was studied the state of spawning grounds of the Kremenchuk reservoir. There are presented results of studies on determination of areas of shallow water sites of the Kremenchuk reservoir, which are suitable for reproduction of fish and their juveniles. It was found that major spawning grounds were upper and lower parts of the reservoir.

Nutrition spectrum and bolus composition of bream of the Kremenchuk reservoir during it’s the most intensive feeding period was studied in comporative-temporal aspect with the aid. There were revealed the dominating role of preferred food (larva and pupa of Chironomidae) and decrease of detritus and sand content in fish bolus. This fact allows ascertaining that there are favorable conditions for bream fattening in Kremenchuk reservoir.

The sexual products of paddlefish (Polyodon spathula (Walbaum)) females in their first year of maturation were of low quality. The highest reproductive indices were observed in broodfish that had been used repeatedly. Testing different hormonal substances indicated that the best paddlefish , arti- ficial reproduction was observed with the application of LHRH-A to stimulate female maturation. The method of obtaining mature oocytes by puncturing the female abdominal wall near the genital opening was noted to be very efficient. There were conducted successful experiments with low-temperature preservation of paddlefish sperm. Survival rate of defrosted sperm cells was not less than 77%.

Authors: ACTIVITY OF IMMUNITY T-SYSTEM IN 2-YEAR OLD LUBIN FRAME CARPS AND AMUR WILD CARPS AND THEIR HYBRID FORMS GROWN AT DIFFERENT STOCKING DENSITY

There are presented data on quantity of separate populations of T- and quantity of B-lymphocytes in blood of 2-year old Lubin frame carps and Amur wild carps and their hybrid forms grown at stocking density of 2500 and 1000 fish/ha. Differences in quantity of T- and B-lymphocytes and their activity in fish of studied genotypes are insignificant.

Analysis of genetic structure at various breeds and hybrid groups of carp was carry out. Most informative for discovering of intergroup variations were malatdegidrogenaza and 6-phosphoglu- konatdegidrogenaza enzymes and locus of transferrin. The polymorphism value of these systems are may promote the objective control of imbreeding power of the fish groups and also the modi- fication of genetic structure in generations and in various breeding conditions.

It was researched the influence of iodine salts KJ and KJO3 which were added to the fish-breed- ing ponds on the activity of hydrocarbon digestion of the Lyubin` scale carps. It was established that the action of 0,1 g/m3 of KJ during 92 days doesn’t cause the changes of medium value of carbohidrase activity in the digestive system of Lyubin` scale carps. The action of KJO3 under the similar condition decreases the cavity carbohidrase activity in the medial part 53% in comparison with control.

It is stated, that a nourishment makes an impact on the content of free amino acid in the organism of the examined fish. Depending on the nourishment of the given species of fish the amino acids that belong to aliphatic and cyclic groups prevailed in their muscles. Absence of free tryptophan in the muscular tissue of all examined fish during the summer period indicates that the feed base was maximum possible for both the predatory fish as well as for benthophage.
