Some biological peculiarities of thornback ray, Raja clavata (Linnaeus, 1758) in the northeast Mediterranean

Abstract

This study was performed to identify the biological peculiarities of thornback, collected using deep trawl from the Northeast Mediterranean between 1999 and 2003. It was determined that 90 individuals were composed of 58.88% males and 41.12 % females; while the lengths ranged from 29.30-64.60 cm, weight varied between of 110.00-1120.00 g and age composition changed from I to VIII. The total length-weight relationship were W=0.0034*L3.1003 and von Bertalanffy’s growth constant in length and weight were also estimated as L∞=79.66 cm, K=0.133 year-1, t0=-3.03 year and W∞=2666.20 g. In addition, it was identified that the exploitation rate is E=0.54 year-1. Therefore, it was estimated that fishing on the thornback stock, and this species stomachs contained mainly Crustacea.
