The article contains basic biological indicators of silver bream spawning stock: average-weighed age, length, weight, condition index, fattness, sex ratio, and spwaning kernel composition. There have been analyzed effects of water temperature and level during spawning period on time and efficiency of repoduction of this species during 1998–2007. It was found that the time of spawning commencemnet did not practically changed during last 10 years.

Growing of marketable production of North American zooplankton-eating representative of sturgeon species — paddlefish was conducted at polyculture with cyprinids (common carp, silver carp, bighead carp, grass carp) in ponds located in the central region of Ukraine. There was used a limited feeding of carp by artificial feeds. Stocking density of 1–3-year paddlefish with average bodyweight from 86,2 to 3345,0 g in ponds with area 72–74 ha varied within 59–85 ind./ha with total stocking density of all fishes 1568–2402 ind./ha. As a whole, environmental conditions of ponds corresponded to biological requirements of studied polyculture objects, average seasonal zooplankton biomass was within 3,9–5,8 g/m3. As a result, paddlefish production was 48,6– 224,3 kg/ha with total fish productivity in ponds from 1067,1 to 1248,8 kg/ha. Average seasonal paddlefish bodyweight gains increased with age from 1,22 до 2,47 kg at average bodyweight of age-2 fish — 1,31–2,14 kg, age-3 fish — 4,26 kg, age-4 fish — 5,82 kg.

The goal of the experiment was to find essential correlation between glucosamine content in zoo- plankton, component of natural nourishment of carp as well as glucosamine content in ingesta and fishing efficiency of ponds. Purpose of investigations was to use index values related to glucosamine content to evaluate carp production with in short-term perspectives. The correlation between selec- ted fraction of high fatty acids (HFA) in zooplankton and content of these fractions in carp meat were also examined. It was noticed that some parameters of glucosamine content in ingesta were statistically significant correlated (P<0,05) with ponds fishing efficiency, especially in reference to carp fry ponds. The correlation between percentage of PUFA-3, PUFA and PUFA-MUFA sum in high fatty acids profile in commercial carp meat and contest of these fraction in high fatty acids profile in zooplankton was also determined highly statistically significant or statistical significant (P<0,05). Taking into account qualitative composition of high fatty acids profile and PUFA-6/3 ratio it can be noticed that biennial production cycle of light commercial carp provides higher dietary value meat than meat obtained in triennial production cycle.

The analysis of the statistical information based on the fish catching of commercial fishes in the sea of Azov for 2004–2008 and the results of researches of AzYugNIRO afford ground for considering the haarder fishery by purse and ring nets a major factor of man’s impact on the structure of commercial part of the haarder population. For the purpose of more rational use of this commercial object the fol- lowings measures are offered on optimization of measures of adjusting of its fishery: the reduction of terms of the haarder fishery by purse and ring nets in the sea of Azov, expansion to the east of fishery district by purse and ring nets, increase of low-limit of mesh in the gears for the haarder fishery.

The idea of increasing the viability of fish embryos and larvae was proposed and experimen- tally substantiated at the Institute of Hydrobiology of NAS of Ukraine by professor V.I. Vladimirov at the beginning of 60-ies of XX century. He examined effect of biologically active substances on fertilized fish eggs, embryos, and larvae as a way of their quality compensation caused by different quality of broodfish. Further studies showed that such biologically active substances as biomet- als, amino acides, biooxidants, and others significantly increase survival rate of fish embryos and larvae during industrial mode of their reproduction.

As a result of stay of carp in water with the promoted concentrations of lead (0,2 and 0,5 mg/l) the common amount of leucocytes in blood decrease in 1,5 and 1,6 times in comparing to the con- trol. Both concentrations of toxicant drew changes in a percentage of blood leucocytes: decline of number of mature forms– neutrophils, basophils and monocutes, increase of maintenance of young cells, in particular lymphoblasts, promyelocytes, myelocytes and metamyelocytes. Subject to the condition presence in the environment of lead ions in concentration 0,2 and 0,5 mg/l phagocytic activity of neutrophils decrease in 1,5 and 1,4 times in comparing to the control.

Distributing of heavy metals in the organisms of fishes of the Kiev reserves is characterized heterogeneity and depends on their physical and chemical properties and functional features of organs and fabrics. In most a copper, iron and zinc, accumulate in a liver, manganese and cobalt — in brachiates. Toxic metals (lead, cadmium) are in a greater degree concentrated in brachiates and skin. Iron and zinc prevail in all of the considered organs and fabrics, minimum concentrations are characteristic for a cobalt and cadmium.

Experimental infection indicate that mosquito iridovirus (MIV), a chloriridovirus, is patho- genic for carp Cyprinus carpio. The cumulative mortality reached up to 60–100% within 8–14 d. Symptoms of inoculated carp included cessation of feeding and decreased ventilation. Just prior to death, the fish were lethargic. The infection was characterized by focal necrosis of the gill, kidney and liver. In inoculated carp, MIV was reisolated on larva Galeria mellonella from gill, kidney, spleen and liver. This is the first time that a virus isolated from a mosquito has been shown to cause mortalities in a fish species.
