On land where once stood a slaughterhouse landfill, remediation of soil was performed by removing 1m of soil and thereby removing organic material. After that, a fish pond construction was done and the land which was used for that purposes was brought from a site outside of the landfill. Prior to starting the fish production, agricultural limestone was applied to the bottom of the empty pond in an amount of 2000 kg/ha. The fish pond was subsequently filled with water from wells in the depth range of 75 to 95 m, and the quality of the water was equal to the quality of second class water in accordance with the regulations of the Republic of Serbia. One-and two-year old common carp were stocked in the fish pond and the total stocking density was 600 kg/ha. During the fish farming the formulated feed with 32% protein and 10% fat was used and besides that a by-products form slaughterhouse (spleen, liver, lung) supplemented with grains. Aeration was provided by the spraying of the well water and by an aerator that pulled the water from the water layers close to bottom of fish pond. The flow of the water was 10 s L/ha. During the production season continuous monitoring of basic environmental conditions, particularly the amount of dissolved oxygen, biological oxygen demand, chemical oxygen demand, quantification of consumption of permanganate, amount of nitrite, nitrate, chloride, total phosphorus, ammonium ions and ammonia and pH was done. Additionally the production parameters and health of the fish were observed. Harvesting density was 5000 kg/ha.
