Abstract

This study was conducted to determine length-weight relationship of horse mackerel Trachurus mediterraneus (Aleev, 1956) from Bulgarian Black Sea coast. Length and weight of fish were measured during May-December 2009, then converted into logarithmic values. The coefficient of determination (r2) of different samples showed high degree of correlation between legth and weight, 0.8571, 0.9716, and 0.9994 for female, male and both sexes, respectively.

Keywords: Horse mackerel, Trachurus mediterraneus, length-weight relationship, Black Sea, Bulgaria
