Abstract

In this study, it was aimed to estimate some biological parameters of horse mackerel (Trachurus trachurus). Totally, 1307 sampled individuals were studied and mean length and weight of sampled individuals were calculated as 12.4 cm and 16.2 g. Sex rate (female : male) is determined as 1:1.02. It was also found that length-weight relationship of all individuals W=0.0049 L 3.17 with an age interval of 0-7 von Bertalanffy growth equation was found as Lt= 20.5 (1-e -0.2313(t+2.996) ). The
