Abstract
The aim of the research was to investigate the influence of nutrition, carp type and location on the fatty acid profile of the carp, and on the meat quality for human consumption. Samples of the hepatopancreas were used from carp fed with: a) commercial pellets, b) grain and natural food. Samples from carp from two different locations were also used: a) Jastrebarsko and b) Draganići. The fatty acid profile was determined using gas chromatography. The variables studied had a significant influence on the fatty acid profile. The most significant differences were visible in the wild type fed with natural food and grain as a supplement. These carp had the lowest concentrations of polyunsaturated fatty acids and the highest concentrations of monounsaturated fatty acids. On the basis of our findings we may conclude that the investigated variables could significantly influence the fatty acid profile of carp and this may be used to obtain higher quality carp meat for human consumption.
