Abstract

The balance of omega-6/omega-3 fatty acids is an important factor in human health. High omega-6 fatty acid content in the diet along with a high omega-6/omega-3 ratio can lead to the development of many chronic diseases. Conversely, higher levels of omega-3 fatty acids such as eicosapentaenoic acid (C20:5, EPA) and docosahexaenoic acid (C22:6, DHA) and lower omega-6/omega-3 ratio are desirable for human health. We determined the lipid content in beluga flesh which was 6.5 %. Monounsaturated fatty acids were the main class of fatty acids followed by polyunsaturated and saturated fatty acids. The EPA and DHA contents of cultured beluga flesh were lower than those of other cultured sturgeon species, which may be due to the contents of these fatty acids in the diet. The content of omega-6 fatty acids (25.7 %) was higher than omega-3 fatty acids (8.58 %), giving an omega-6/omega-3 ratio of 3.00.
