Monitoring of physical and chemical indexes of salt water of coastal area of aquatorium of the Odesa Bay for determining the corresponding location for open-air cages for maintenance of marine mammals
AbstractIn the article data physical and chemical indexes of salt water in the aquatorium of the Odesa Bay in the last few years are presented in the dynamics. Researches were conducted in accordance with the subjects of research work of «Research of parameters of environment for maintenance of marine animals in the conditions of aquatorium of the Odesa Bay in interests of MNF of Armed forces of Ukraine» of the Scientific research center of Armed forces of Ukraine «State Oceanarium» and on the basis of the official figures given by the «Odessa regional laboratory center of state sanitary and epidemiological service of Ukraine». Examining possibility of maintenance of dolphins and sea lions in the conditions of aquatorium of the Odesa Bay, it is necessary to take into account that among the basic sources of contamination of this area of the Black Sea along the coastal channels of river waters of Dnepr and South Bug, there is domestic wastewater from stations of biological purification of water «Southern» and «Northern», thundershower flows of cities Odessa and Chernomorsk, of objects Odessa, South and Black Sea ports, dockyard «Ukraine» and other coastal objects. Also, as catalysts of negative influence on the ecosystem of the Black sea, the unfavorable weather factors of this area of coast can be considered, namely: high temperature of salt water in summer months, periodic high winds, possible formation of ice in a winter period of and other. The aim of the advanced study became the monitoring of separate areas of coast of the Odesa bay on the basic physical and chemical, and also bacteriological indexes of salt water and changes of weather terms during a year for determining the optimal location of maintenance of marine animals in open-air cages. It is set on results researches, that only seasonal maintenance of marine mammals in open-air cages in the aquatorium of the Odesa Bay (during 6–8 months of the year) can be applied, by reason of disparity of row of sanitary epidemiology indexes of salt water to the set rules and norms. One of variants of decision of this question, the combined type of maintenance of animals was offered, that consists in translation of them in the apartment of the covered pool with the natural cleared salt water on the periods of disparity of salt water to the basic sanitary epidemiology requirements or at formation of ice in an aquatorium in a winter period.
