Chemical and fatty acid composition of muscle tissue of carp (Cyprinus carpio) at different frequency of feeding

Provedeno je istraživanje utjecaja učestalosti hranidbe mlađi šarana (Cyprinus carpio L.) na kemijski i masenokiselinski sastav tkiva. Ribe su hranjene na ribnjacima Grudnjak i Jasinje 2, 3 i 4 puta dnevno (2x, 3x, 4x) potpunom krmnom smjesom za slatkovodnu ribu (35% SP i 9% SM) jednakom količinom hrane (2% ukupne mase ribe) u trajanju od 90 dana. Rezultati su ukazali na značajnije nakupljanje masti u mišićnom tkivu kod riba s nižom učestalosti hranidbe. Kod riba hranjenih višom učestalosti hranidbe, omjer n-3/n-6 masnih kiselina tijekom istraživanja bio je viših vrijednosti.A study was conducted on the effect of feeding frequency of common carp juveniles (Cyprinus carpio L.) on the chemical and fatty acid composition of muscle tissue. Fish were fed a complete feed mixture for freshwater fish (35% SP and 9% SM) with an equal amount of feed (2% of the total weight of the fish) in Grudnjak and Jasinje ponds 2, 3 and 4 times a day for 90 days. The results indicate that more fat accumulates in muscle tissue in fish fed at a lower feeding frequency. Fish fed at a higher feeding frequency had a higher ratio of n-3/n-6 fatty acids during the study
