Abstract

Sturgeon farming in recirculating aquaculture system has a number of advantages over natural breeding or breeding in fish ponds. Breeding conditions in recirculating aquaculture system can significantly reduce the time of fish growth and development to production conditions, effectively use water resources, and, in general, create optimal temperature, hydrochemical, and other conditions for fish farming, as well as balance feeding. However, the use of intense forms of fish breeding in a recirculating aquaculture system, in some cases, can lead to deterioration of the hydrochemical regime, temperature fluctuations, change in pH of the aquatic environment, contributing to the activation of opportunistic and pathogenic microflora as the etiological origin of various bacterial pathologies among fish. The authors define the nosological profile of the pathology of sturgeon fish in the university aquarium complex based on the retrospective and real-time epidemiological monitoring. The article presents the results of clinical, pathological, and laboratory studies of pseudomonosis of sturgeon, as well as the effect of pathomorphological processes on the food safety of fish products.
