Two-year-old coregonines (broad whitefish Coregonus nasus) were grown in cages on experimental feeds. After 55 days (the feeds expiry date was two months) the feeds began to spray with a solution of vitamin C, which increased the vitamin content in liver and muscles and retained a high level of Omega-3 acids in those tissues. The fish was growing at the same growth rate in all fish cages with normal blood values. The fish which did not receive additional C Vitamin had reduced content of polyunsaturated fatty acids in muscles, especially docosahexanoic acid – 15,9% versus 21,8%, while the content of monounsaturated oleic acid was increased – 34,5 against 26,7%. All fishes had similar fatty acid profile in their liver. Apparently, it is the muscles that are a reserve of essential fatty acids for the liver and other organs having an enhanced need in Оmega-3 acids
