The objects of this research were the mirror carp and trout growth in fishfactory «Biserovskiy ». The purpose of this research was veterinary and sanitary estimation of these fish. We conducted a pathoanatomic autopsy and inspection of fish, determined organoleptic characteristics and conducted microbiological investigation on the presence of coliforms (E. coli), Listeria monocytogenes, S. aureus in the fish. Veterinary-sanitary examination was conducted in accordance with the reference book «Veterinary and sanitary examination of freshwater fish» and «The rules of veterinary and sanitary examination of freshwater fish and crawfish». Microbiological investigation was conducted in accordance with «Instruction of sanitary and microbiological control of alimentary products from fish and marine invertebrates», GOST 26670-91 «Food products. Methods for cultivation of microorganisms», GOST 10444.15-94 «Food products. Methods for determination of quantity of mesophilic aerobes and facultative anaerobes», GOST 31747-2012 «Food products. Methods for detection and quantity determination of coliformes », GOST 32031-2012 «Food products. Methods for detection of Listeria monocytogenes », GOST 31746-2012 «Food products. Methods for detection and quantity determination of coagulase-positive staphylococci and Staphylococcus aureus». According to the results of the research, these fish met the requirements of regulatory documentation, which confirms the safety of products for the consumer. Keywords: fish farming, mirrorcarp, trout, pathological investigation, organoleptic investigation, microbiological investigation, veterinary and sanitary examination.
This article deals with the problem of wastewater treatment at the Fergana poultry farm (FPF). The results of hydrochemical and sanitary-bacteriological studies are analyzed. Treatment facilities were built at the Fergana poultry farm and put on balance, which included the following objects: a grate crusher, horizontal sand traps, 2-tier settlers, biological oxidation and stabilization ponds (otherwise known as BOX ponds). After the accumulation of ten daily volumes of waste water in the BOX ponds, they were transferred to the contact mode of operation, with the introduction of an adapted microalgae complex. Hydrochemical and bacteriological analysis of the selected samples were carried out. The results were analyzed for the content of E. Coli bacteria; the concentration of pH hydrogen ions, COD, suspended solids, dissolved oxygen, ambient air temperature, and the amount of alkalinity. The results of hydrochemical studies on self-purification of wastewater in BOX ponds were analyzed. According to the conducted research, poultry farm waste water that was subjected to disinfection processes in BOX ponds becomes epidemiologically safe if the concentration of microalgae introduced into the system to intensify self-purification processes is equal to or exceeds 500 ml. Studies have found that this indicator can be increased at the end of cleaning and disinfection to 99,9% [8, 14]. After the cleaning and the decontamination is completed, waste water prepared in the BOX ponds of the Fergana poultry farm can be used for irrigation, or in fishbreeding and biological ponds for growing fish-planting material.
