This study investigated the proximate composition and fatty acid profile of the carp muscle fed with pig manure. Carp with 4-10 months of age were collected in Santa Catarina. Muscle samples were sliced and then triturated in a multiprocessor and stored under gaseous nitrogen atmosphere (-18°C). The moisture, protein, and ash contents (%) were as follows: 72.24; 14.85; e 2.16, respectively, for carp feed artificial food; and 83.33; 14.48; e 3.49 for carp feed pig manure. The contents of sodium and potassium were: 0.491% and 1.20% carp/artificial food; 2.28% and 0.367% carp/pig manure. The total lipids contents also presented significant differences: 9.88% carp/artificial food, and 1.69% carp/pig manure. Fatty acid profile showed similar tends in both muscles. Therefore, a significant difference in the total lipids and mineral contents of the carp tissue feed pig manure was detected, though the observed variation in total lipid content wasn’t reflected in the fatty acid composition.
