For the first time, the quantity of protectors of cardiovascular deceases—omega-3 polyunsaturated fatty acids, eicosapentaenoic (20:5n-3, EPA) and docosahexaenoic (22:6n-3, DHA), obtained through fish (Eurasian perch) catch in water bodies of different trophic status was determined. A formula was drawn to calculate the quantity of obtained EPA + DHA (kg km–2 year–1) depending on the concentration of total phosphorus in water. It is found that the maximum quantity of EPA + DHA can be obtained by humans from fish caught in mesotrophic water bodies.
