Control of fish parasites in aquaculture

Abstract

Abstract This paper describes the results of parasitological monitoring of pond farms in the Krasnodar region. It was found that in the warm-water aquaculture of various systems, 25 species of fish parasites were invaded, and the fauna of parasites was determined. The obtained results are the basis for the analysis of the system of medical and preventive measures and actualize the development of new means and methods of treatment and prevention of diseases. It is established that the complex anthelmintic drug, according to the generally accepted classification of chemical compounds in accordance with the degree of danger, can be attributed to moderately hazardous compounds, and by cumulative properties - to the group of substances with weakly expressed cumulation. With repeated administration of the new drug to fish, there were no significant changes in the clinical status, some hematological and biochemical parameters, which is one of the necessary conditions for the possibility of using anthelmintic in clinical studies. As a result of a single therapeutic feeding with the use of a combined anthelmintic at a dose of 50 mg/kg, the 100% extensive and intensive efficiency of the deworming of carps invaded by Philometroides lusiana and Bothriocephalus acheilognathi was obtained.
