Monthly changes in proximate and fatty acid compositions of Black Sea anchovy were searched during catching seasons
in this study. Moisture content of anchovy was at the lowest level (64.93%) in October, whereas it reached the maximum
level in April (74.32%). In contrary to moisture, lipid level was at maximum level (16.32%) at the beginning and gradually
declined (7.9%) towards the end of fishing season. Significant differences in lipid levels of anchovy was observed in all
sampling months, whereas its ash content was differed significantly (P<0.05) only in December and April. In addition, the
levels of C16:0, C14:0 and C18:0 in saturated fatty acids (SFA), C18:1n9 in monounsaturated fatty acids (MUFA) and
C22:6n-3 (docosahexaenoic acid, DHA) and C20:5n-3 (eicosapentaenoic acid, EPA) in polyunsaturated fatty acids (PUFA)
was the predominant fatty acids. EPA level gradually declined, while DHA increased from October to April. Furthermore, the
average levels of n3 and n6 were found to be 30.33% and 4.43%, respectively. Significant changes were observed in fatty acid
composition, particularly in DHA, of anchovy during the fishing season.
