Seasonal dynamics of the total lipid content in the body of the anchovy Engraulis encrasicolus (Linnaeus, 1758) in 2017-2020

Abstract

The analysis of the dynamics of lipid content in the body of anchovy (Engraulis encrasicolus) in various periods of its life cycle from 2020 to 2022 inclusive. The article shows that the difference in the content of energy-plastic substances in the body of anchovy is clearly traced depending on the age of the fish: the number of lipids in fingerlings is lower than in older individuals. Based on the analysis of the inter-seasonal dynamics of the lipid content in the body of the anchovy, it was found that the minimum lipid content is typical for fish in April, and the maximum is observed in October. Analysis of the interannual dynamics of the lipid content in the anchovy body at the end of the feeding period showed that in the last three years there has been a trend towards a gradual increase in their number to the level of 16-18%.
