Oliinyk O. Crustacean diseases: spreading, diagnostics and medioprophylactic measures

In the dissertation spreading of carp fish Crustacean diseases is established, diagnostic methods for carp fish Crustacean diseases are analyzed, Diamant, JavelClade medicines are suggested for medical treatment of fishes harmed by Crustaceans, effect of medicines on carp fish microbiocoenosis, blood, organs and tissues is studied. Research results on efficiency of Javel-Clade and Diamant medicines use in the different hydrochemical conditions are presented. Economic effectiveness of the use of Diamant and Javel-Clade medicines is established. During the examining of spreading of carp fish Crustacean diseases it was found that more frequently lesion had a character of the mixed invasion. Lethal and therapeutic concentrations for Diamant and Javel-Clade medicines were established during toxicological examination on laboratory objects. During examination of fishes, harmed by Crustaceans, after treatment, no pathological changes in tissue structure and structure of fish’s organ cells were detected. At the same time, short-term effect of the medicines studied stimulates specific changes of morphostructure. Recommended concentrations of these medicines don’t cause sudden qualitative and quantitative changes in blood. Since medicines for fish, treatment causes partial loss of microbes on fish body surface, gills and interns.
