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

Year 2008, Volume: 25 Issue: 3, 221 - 228, 01.09.2008

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.

Kuzeydoğu Akdeniz’deki Deniz Tilkisi Raja clavata (Linnaeus, 1758)’nın Bazı Biyolojik Özellikleri

Year 2008, Volume: 25 Issue: 3, 221 - 228, 01.09.2008

Abstract

Bu çalışma, 1999-2003 yılları arasında dip trolü avcılığından elde edilen Kuzeydoğu Akdeniz’deki Deniz Tilkisi (Raja clavata Linnaeus, 1758)’nin bazı biyolojik özelliklerini belirlemek amacıyla gerçekleştirilmiştir. İncelenen 90 adet bireylerin % 58,88’inin erkek, % 41,12’sinin ise dişilerden oluştuğu saptanmış olup; incelenen balık boylarının boy ölçüm değerlerinin minimum 29,30 cm ve maksimum 64,60 cm arasında değişirken; ağırlık değerlerinin 110,00-1120,00 g kadar değişim gösterdiği ve yaş gruplarının I. ile VIII. yaşlar arasında değiştiği saptanmıştır. Boy-ağırlık ilişkisinin W= 0,0034*L3.1003 ve von Bertalanffy Boyca ve Ağırlıkça büyüme sabitlerinin L∞= 79,66 cm, K= 0,133 yıl-1, t0= -2,70 yıl ve W∞= 2666,20 gr olduğu hesaplanmıştır. Ayrıca stoktan yararlanma oranının E= 0,54 yıl-1 olduğu; böylece bölge deniz tilkilerinin avcılık baskısının oluşmaya başladığı ve buna ek olarak bu türün mide içeriğinin temel bileşenini kabukluların oluşturduğu belirlenmiştir
