Summary
The common carp usually has been delivered to the market surive. Since the consumers started preferring otherwise, the processing becomes more important and so does the dressing percentage (the relationship between the useful part of the fish and its total mass). Commercially, it directs the selection towards the parameters involving the level of production. Hence, the aim of this paper is to assess the phenotypic correlation for the morphological parameters that influence the dressing percentage. The investigation was performed on the marketable size 3-years-old carps from the farms of Končanica and Našička Breznica. The sex and scale groups were treated separately. Nine meristic and twenty-seven morphometric parameters (23 lengths and 4 masses) were analyzed. The dressing percentage was determined as the relationship between the total mass and mass without the head, gills, viscera and gonads. The statistical analysis involved correlation coefficients (r) and their significance (p
