Some biological properties of different populations of the atlantic horse mackerel Trachurus trachurus (L.) in Turkish seas
Özet
Age, growth, sex, and condition of different populations of the Atlantic horse mackerel, Trachurus trachurus (L.) in the Turkish seas were determined from 300 specimens between November 2010 and March 2011. Fork length and total weight of the specimens ranged from 10.0 to 18.9 cm and from 12.81 to 81.71 g, respectively. Maximum age group was determined as IV, and sex ratio in samples did not differ significantly from a 1: 1 ratio for all locations except for Bandirma, where it was skewed towards males (chi(2) test, p> 0.005). Weight increased allometrically for [Zonguldak (BS), Bandirma (MS1), Edremit (AS1), Izmir (AS2), Marmaris (AS3)] populations together with b= 2.881, b= 2.973, b= 3.210, b= 3.120, b= 2.820 respectively except for b= 3.004 for Sarkoy (MS2) as isometry.
