The objective of this research was to evaluate the effect of rearing method (fed on dry diet, pig manure, or chicken manure) and the method of transport (live fish or on ice) on the quality of minced meat of Hungarian carp Cyprinus carpio. In order to obtain the minced meat, the muscle was triturated, vacuum wrapped in polyethylene packing and conserved under refrigeration 2±1°C. Analyses of carcass yield and muscle proximal composition were carried out. The effect of storage time (1, 4, 7, 15, and 30 days) was analyzed in terms of TVB (total volatile bases), pH, PI (peroxides value) and TBA (thiobarbituric acid). Carcass yield of the carps cultivated on pig manure and transported on ice was statistically higher than those transported alive, reaching 41.5%. However, there was no significant difference of carcass yield of carps fed on dry diet or chicken manure independent of the transport method (P>0.05). Protein and lipid content were not significantly different (P>0.05) when considering the transport methods. TVB, pH, PI and TBA showed interactions (P<0.05) between rearing methods and the transport methods. TVB and pH were in accordance to the values stipulated by the Brazilian legislation. PI and TBA were low (maximum of 14.73mg peroxide kg-1 and 0.480mg malonaldeyd kg-1, respectively), showing that the minced meat can be preserved longer than 30 days. Quality of the minced meat was not affected by the transport method.
