Chemical composition of meat in two cyprinid species
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2009, Vol 2, Issue 3
Abstract
The biochemical analyses of the meat were determined in two species of carps, respectively Cyprinus carpio and Ctenopharyngodon idella. We worked on four groups of 10 fishes each (two groups for C. carpio and two groups for Ct. idella). One group from both species was fed with special fodder, and the other two groups were fed with clover (Trifolium pratense) and reeds (Phragmites communis) for C. carpio and Ct. idella respectively. The determination was made in the laboratory of chemical analyses of the Faculty of Animal Sciences, University of Agricultural Sciences and Veterinary Medicine Iași and we determined the content of the meat in proteins, fat, dry substance and minerals. The characteristic chemicals of the meat were determined on the extracted sample from the lateral musculature of the body. Biochemical analysis of meat from the four carp lots shows that protein content of meat is higher in groups which received combined feed compared to group which individuals were fed with natural food. Therefore, in case of feeding fish with combined fodder the protein content of meat increases, which proves a good recovery of protein in feed. Fat content and minerals in cyprinid meat are both higher in individuals fed with combined feed compared to those fed with natural components. When fat content in meat is higher, the dry matter content in meat is higher.
