Sažetak
Common carp is a widespread freshwater fish. It was domesticated over a thousand years ago. People developed different lines of common carp which differ in physical appearance, time of development and food utilization. In this research we used hepatopancreas of carps fed with formulated feed – leather carps (carps without scales) and both leather and fully scaled carps fed with grains and natural food (zooplankton, zoobenthos, phytoplankton and aquatic plants). Leather carps which were fed with formulated feed had much higher level of linoleic and linoleic acids, while the level of these two acids was lower in fully scaled carps fed with grains (p< 0.05). Level of arachidonic acid was much higher in leather carps fed with grains (p< 0.05) than in the other two lines of carp. Leather carp fed with formulated feed had the highest level of PUFA, n6 and n3 fatty acids. Leather carp fed with grains was more similar to the same line then to the fully scaled carp from the same habitat. Fully scaled carp fed with grains had lower level of PUFA, n6 and n3 fatty acids and the level of MUFA was slightly higher than in the other two lines. In conclusion, food has an impact on fatty acid profile, but different lines of common carp and their different metabolic needs must be considered in result interpretation. In habitats where these lines of carp live together, feeding should be balanced so that the development of one line would not be slower.
