Ispitivanje uticaja korišćenja otpadnih voda iz klanice na zdravlje i proizvodnju mesa šarana (Cyprinus carpio) bezbednog za ishranu ljudi

Meat industry is characterised by high water consumption and is undoubtedly a significant source of organic pollution of the environment. There are both ecological and financial motives for water purification which intertwine and complement each other. The use of available technology for fish farming in slaughterhouse industry is an ecological solution for removal of organically loaded water used in slaughterhouses. On the other hand, such integrated system carries certain risks mostly related to the safety of fish meat produced in this way.The aim of the research carried out in this doctoral thesis was to examine the effect of the use of wastewater from slaughterhouses on the health of carp and safety of carp meat for human consumption.The research of this doctoral thesis was carried out in several stages. A system for wastewater purification was built on the property of ‘Djurdjević’ Meat Industry in Pećinci. The efficiency of wastewater treatment plant was examined by using chemical analyses of water in different water purifying stages. After this, a fishpond was built on the same property. It was mostly supplied with the water from the system for wastewater purification from the slaughterhouse. The water from purifiers goes to pre-fishery where purified water is aerated, after which the water goes into fishpond where a part of nutrients from purifiers is used for carp nutrition. The water is then used for irrigation of the soil surrounding the slaughterhouse. This way, the fishpond has an impact on increasing the quality of purified wastewaters and reaching limit concentrations set before the inflow into a natural recipient. Carp fingerlings in good health were stocked in the fishpond. Carp was produced in optimal ambient conditions by using purified water originating from slaughterhouses and by adding well water. A good quality of meat was achieved by feeding fish balanced meals...
