The milt of individual males of Siberian sturgeon (Acipenser baerii) and sterlet (Acipenser ruthenus) was frozen without cryoprotector (at -79°C) or cryopreserved with methanol as the cryoprotector. The activity of arylsulfatase (AS), acid phosphatase (AcP), β-N-acetylglucosaminidase (NAGase), and protein concentration was determined. The protein concentration and enzymatic activities in supernatant obtained after cryopreservation were higher than in milt plasma, but they were lower than that in the material obtained after freezing at -79°C. The protein and enzymatic leakage of sterlet spermatozoa was statistically higher in supernatants that had been frozen at-79°C than in those that had undergone cryopreservation. Differences in the protein and AS leakage the Siberian sturgeon supernatants were also observed.

DNA finferprinting analysis based on microsatellites was applied for separation of mixed gynogenetic offspring of Siberian sturgeon (Acipenser baeri) and individuals from commercial production. Variation at 11 microsatellite DNA loci was surveyed for parent of gynogenetic offspring. Thus microsatellite DNA profiles in studied loci were known and this key-point was aplied in segregation analysis of mixed fish. In results 108 individuals of 281 studied were verified as gynogenetic offspring. The present survey of microsatellite variation demonstrated a reliable tool for separation of mixed group of fish.

This paper presents the results of studies on the feeding and growth of Siberian sturgeon in the first year of life in monoculture in earthen ponds. The digestive tracts of the fish contained the following orders of invertebrate fauna: Cladocera, Coleoptera, Copepoda, Diptera, Heteroptera, Mollusca, Oligochaeta and Trichoptera. Diptera and Cladocera dominated. Small amounts of Copepoda, Heteroptera, Mollusca and Trichoptera were also noted. The average indexes of weight contribution reached the highest values (1.09 - 1.70 g) in the spring-summer season, while the value in the fall sample was 1.41 g. The highest values of frequency of occurrence (100%) of the dominant Cladocera and Diptera in the food and of feeding intensity (179 - 275‱) also occurred in the spring-summer season. The highest values of the percentage indexes (> 50% - eudominants) were reported for plankton crustaceans from the order Cladocera in spring and summer. After the spring sturgeon had adapted to the new environmental conditions, a clear increase in the growth rate was observed, and after the water temperature dropped below 13ºC growth stopped.

Skin mucus and the digestive tract contents of Siberian sturgeon (Acipenser baeri Brandt), feed and water were analyzed during intensive tank rearing. The analyses included the total number of heterotrophic bacteria on common agar at 22°C (TVC 22°C) and 37°C (TVC 37°C), the number of coliforms (TC), fecal coliforms (FC) and fecal streptococci (FS). The water was evaluated for nitrogen cycle bacteria - proteolytic, ammonifying and nitrifying bacteria of phases I and II. The lowest numbers of TVC 22°C (83600 CFU cm⁻³ ) and TVC 37°C (7040 CFU cm⁻³ ) occurred in inflow water. The highest numbers of TVC 22°C (169200 CFU cm⁻³ ) were present in the tanks, while TVC 37°C (7280 CFU cm ⁻³) were the most numerous in outflow water. Statistical analysis confirmed the influence of sturgeon rearing on the densities of these bacteria in the water. No such relationship was detected for sanitary indicator bacteria (TC, FC and FS), the numbers of which did not significantly differ between inflow or outflow water.

The present study evaluated the weight composition of Siberian sturgeon food, the species feeding intensity in a 24-hour cycle (as consumption index I - ‱), and its daily food ration (as a percentage of average fish body mass). The study was conducted on fish in their first year of life which were being reared in a 0.05 ha pond with a maximum depth of 2 m and an average depth of 1.2 m. Chironomid larvae, mainly Chironomus plumosus L., were the principal food component found in the digestive tracts of all the fish in all the samples. Some butterfly and stone-fly larvae were also noted. Feeding intensity reached the highest values at night. Calculated according to Thorpe (1977), the daily food ration of Siberian sturgeon with an average body mass of 20.3 g and at an average daily water temperature of 14.2°C was 5.4% of fish body weight.

The objective of the experiment was to compare the growth rate in two groups of Siberian sturgeon fry, one of which was infested with metacercariae of Diplostomum, the infestation degree was from 1 to 160/fish. The fish fed on natural as well as artificial food; the latter was given at the rate sufficient to cover 50% of the fish requirements. The average initial body weight in the control group was 16.8 ± 1.9g, and in the group with Diplostomum - 28.4 ± 3.6 g. During the period of favorable temperatures, viz. for about 90 days, the fry was showed satisfactory growth, but the growth rate becaine inhibited as the temperatures decreased to below 12°C, so that throughout the wintering period the fish weight decreased by some 10%. Fish from the control group showed a higher growth rate than the infested ones, and by the end of the experiment the controls weighted 7.5% more than the infested group in spite of their lower initial weight.
