%X The aim of this study was to determine the yield carcass of all categories of cyprinid fish reared in ponds in Serbia. Samples of two and three-year old carp, two-year old silver carp and grass carp were taken in the winter from a pond where the production is organized in a semi-intensive system. The three-year old carp was sampled from two ponds. In one case, it fed on barley, maize and wheat in the following proportions 40:30:30, while in the second case it fed on complete diet mixtures. Also, the samples of two-year old carp were taken from ponds where they fed on complete feed mixture. Dressing percentage was the most favourable in common carp (67%), followed by silver carp (62%), and it was the least in grass carp (60%) (p<0.01). The best yield (66%) was obtained in two-year old carp, followed by one-year old carp (64%), and the worst yield was determined in three-year old carp (58%) (p<0.01). Carcasses yield was better in two-year old carp fed on pelleted feed (68%) than in carp of the same age fed on grains (66%) (p<0.01). The values of dressing percentage measured in three-year old carp reared in the semi-intensive system was 56%, and 59% in three-year old carp fed on pelleted complete feed mixture. Fish species, age, system of husbandry and diet showed a significant effect on carcasses yield. The highest dressing percentage and weight of fillets was noted in two-year old carp fed on complete feed, and it was a result of lower weight of internal organs and associated fat. The obtained results may be helpful in creating the best strategy for the selection of raw fish for fish manufacturing.
