Eastern Black Sea horse mackerel, Trachurus mediterraneus (Steindachner, 1868) In The Otolith features and some population parameters

In this research, otolith dimensions-fish length relationships and some population parameters of 439 Mediterranean horse mackerels caught from Trabzon (in Eastern Black Sea) between April-December have been examined. Lenght and weight of specimens have been ranged (avarage plus or minus SH) 12.70 plus or minus 0.09 cm and 18.05 plus or minus 0.35g, respectively. The lenght, width (height) and weight of otoliths were measured from each specimens and were determined as 4.38 plus or minus 0.03 mm, 2.44 plus or minus 0.02 mm and 0.0079 plus or minus 0.00015g, respectively. The relationship between lenght and weight of fish y=0.0093x2.9565 (r2=0.97; P
