    Belousov, V.N.; Federal State Budgetary Scientific Institution "Azov Sea Research Fisheries Institute" (Azov Sea Research Fisheries Institute (AzNIIRKH)Rostov-on-Don, Russia, 2017)
    Complex studies of bioresources, biological foundation of valuable fish species reproduction, aquaculture, ecological problems and nature protection measures in fishery waterbodies of the Azov and Black Sea Basin have been considered for the period 2014-2015.
  • On the growing young stellate sturgeon (Acipenser stellatus) of the Azov population by combined method in hatcheries of the Azov-Don Region

    Pavlyuk, A.A.; Gorbenko, E.V.; Burtasovskaya, L.A.; Panchenko, M.G.; Belousov, V.N. (2017)
    The article deals with some aspects of raising young stellate sturgeon in a sturgeon hatchery of the Azov-Don region by applying a combined method. Hydrochemical parameters and feeding conditions during juveniles’ rearing in the sturgeon hatchery by a combined method are described; the stellate sturgeon growth rate is registered at the stage of early ontogenesis. The main problems arising during the incubation of the larvae in pools and rearing ponds have been revealed and the effects are shown of violation of technology exploitation in the ponds where stellate sturgeon fries are growing.
  • Evaluation of genetic diversity in Russian sturgeon breeders kept at the Don sturgeon farm “Azdonrybvod”

    Nebesikhina, N.A.; Lepeshkov, A.G.; Ivanova, E.A.; Timoshkina, N.N.; Belousov, V.N. (2017)
    Genetic diversity has been assessed in the breeders of Russian sturgeon from the broodstock maintained in the Don sturgeon hatchery. Six individuals are revealed with the mitotype of Caspian origin. The breeders, produced and raised from eggs in the hatchery, have a trend to preserve new STR-alleles while the alleles specific to wild breeders disappear.

    The data over the past 5 years are summarized on the release of semi-anadromous bream and pike-perch into a natural waterbody, as well as on their morpho-functional state before their downstream migration. The current state of hatcheries in the Azov-Don region is analyzed. Some aspects of saving these valuable fish species of the Azov Basin have been determined.
  • Status of reproduction of anadromous fish species (Russian sturgeon Acipenser gueldenstaedtii, stellate sturgeon Acipenser stellatus, vimba Vimba vimba, shemaya Chalcalburnus chalcoides mento) and prospects of fish ranching

    Gorbacheva, L.T.; Mirzoyan, A.V.; Vorobieva, O.A.; Burtasovskaya, L.A.; Panchenko, M.G.; Gorbenko, E.V.; Zipelt, L.I.; Pavlyuk, A.A.; Valiev, M.S.; Belousov, V.N. (2017)
    Data are presented on the status of artificial reproduction and restocking success of the Azov Sea anadromous fish species over the last five years. The morphofunctional state of the juveniles is analyzed at the stage of their release into a natural waterbody; adaptive abilities of the juveniles to changing environmental conditions at the time of their migration into the sea are predicted. The wild anadromous migrating fish and sturgeon spawners from the broodstock are characterized and their reproductive potential is estimated. Some aspects are considered of improving the efficiency of reproduction (environmental) complex in order to preserve the most valuable aquatic biological resources of the Azov Sea, and the development of pasturable fish culture that is one of the priorities of aquaculture.
  • Evaluation of the azole pesticides toxicity to freshwater crustacean Daphnia magna Straus

    Fedorova, E.A.; Zinchuk, O.A.; Vlasenko, E.S.; Belousov, V.N. (2017)
    A comparative assessment of the toxicity of the azole pesticide action on the processes of Daphnia life is made. It demonstrates the different intensity of toxic effects of the xenobiotics analyzed. The findings of chronic experiment allowed to determine inoperative and threshold concentration of the substances studied. It was found out that for the same content of active substance (metsulfuron-methyl) Singer showed great toxicity, which is caused by the presence of more toxic components in the mixture. It was concluded that in this case, more rational for the environment is the use of the herbicide Laren, as less dangerous to aquatic organisms studied.

    Mkhitaryan, I.D.; Belousov, V.N. (2017)
    Research on cesium-137 concentrations in the water bodies of the Azov-Black Sea basin has been conducted. Comparative analysis of the results for the years 2014-2015 have shown that the specific volume activity of 137Cs in the Azov and Black Sea ecosystem is at the background level, typical of recent years, and agrees with its half-level period. The Chernobyl trace remains the main source of radioactive cesium as before.
  • Dependence of modern fungicides’ toxicity on their chemical structure with regard to fish at early stages of their development and zooplankton

    Shcherbakova, N.A.; Levina, I.L.; Zherdev, N.A.; Fedorova, E.A.; Stroeva, E.S.; Zinchuk, O.A.; Belousov, V.N. (2017)
    Some modern fungicides belonging to five chemical classes and their acute toxicity to embryos and pre-larvae of sturgeon (sterlet, bester, sturgeon) and Daphnia have been studied. The relationship is found between the chemical structure and the toxicity of fungicides which has been defined by some toxicometric parameters. The degree of toxicity is found to depend on their chemical structure. It was detected that the most dangerous for sturgeon and zooplankton are the strobilurin fungicides and dithiocarbamates. Carboxamides of the last generation have a wide range of toxic effects - from high to low toxicity.
  • State of antioxidant protection and detoxification systems in the tissues of gobies and carp fish after exposure to fungicides of a new generation

    Levina, I.L.; Kuznetsova, L.Ya.; Shcherbakova, N.I.; Zinchuk, O.A.; Belousov, V.N. (2017)
    The effect of two novel carboxamide fungicides, Ethaboxam and Boscalid, on round goby fry and carp fingerlings has been studied. Boscalid is characterized to be highly toxic when applied to round goby fries, Ethaboxam is of medium toxicity to commercial fish species. In the early stages of intoxication (1st - 4th day) the threshold concentrations of the fungicides acted as stressors and resulted in the stimulation of protective systems of the antioxidant protection and detoxification in the liver and gills of carp and round goby tissues, which hindered the development of fungicide intoxication. Intensification of lipid peroxidation processes led to the inhibition of superoxide dismutase activity alongside with the increased activity of catalase, esterases, glutathione-S-transferase, while glutathione content in fish tissues decreased gradually.

    Korotkova, L.I.; Sevostianova, M.V.; Belousov, V.N. (2017)
    The amount of organochlorine pesticides has been monitored in the water, bottom sediments and some commercial fish species in the Azov Sea over the years 2014-2015, and the results are presented. There were found some locations with increased concentrations of toxicants in the sea water and bottom sediments. Spatial distribution of OCP in the Azov Sea in different seasons of 2014-2015 is characterized.

No significant decrease in OCPs and PCBs has been observed. However, in 2015 the OCP and PCB concentrations exceeded admissible concentrations set by “Hygienic requirements for safety and nutritional value of foods. SanPiN “. Persistent penta- and hexachlorbiphenyls have been identified in the fish organs and tissues, among those some dangerous dioxin congeners have been detected.
