Current state of parasithofauna of plant-and-vegetable fish in the Mingachaur reservoir

The research objective was the definition of specific structure of parasites of herbivorous fishes in natural reservoirs and the development of methods of fight against various diseases of fish on farms, and also us- ing the material at fish farms creation. The object of the research was parasitological materials collected from fishes of a grass carp (Ctenopharyngodon idella) and a white silver carp (Hypophtalmichtys molitrix) living in the Mingachevirsky reservoir in 2016-2017. 42 fish speci- mens were investigated by the method of complete par- asitological dissection. As a result of research 6 types of ichthyoparasites were found in these fishes. From them1 species refers to infusoria, 3 species to monogeneans, 1 species to trematodes, 1 species to crustaceans. Fixing, storage and processing of collected material were carried out by standard methods. For the research fresh fallen asleep fishes were used only. All tissues and bodies were investigated by a compressor method by means of binocular magnifying glass of MBS-9 increasing × 25...
