Abstract

This study was performed in order to assessment of the turbot (Scophthalmus maximus) Stock from Southeastern Black Sea during April-September 1990 and September-October 1991. From the length-age data for both sexes, the following population parameters were estimated: Length-Weight relationship, $W=0.0085*L^{318}$; v. Bertalanffy growth constants, $L_infty$(mm) = 825.7, $K(year^{-1})$ =0.17, $t_0$ (year)=-0.93, $W_infty$(g) = 10590.43; total mortality and its components, Z=0.48, M=0.30 and F=0.18. Standing biomass of the turbot between 0 and 100 m depth range in September-October 1991 was found to be 407.6 tonnes and also there was an under exploitation rate on this stock as a rate of E=0.37.

Özet

Bu çalışma. Güneydoğu Karadeniz'deki Kalkan Balığı (Scophthalmus maximus) Stoku'nun durumunu belirlemek amacıyla Nisan, Eylül 1990 ve Eylül-Ekim 1991 tarihleri arasında yapılmıştır. Her iki cinsiyetin yaş-boy verisi kullanılarak populasyon parametrelerinden boy-ağırlık ilişkisi, $W=0.0085*L^{3.18}$ ; v.Bertalanffy büyüme sabitleri, $L_infty$ = 825.7 (mm), K=0.17 $(yıl^{-1})$ . $t_0$ = -0.93 yıl, $W_infty$ = 10590.43 (g); toplam ölümlerin üssi katsayısı ve bileşenleri, Z=0.48, M=0.30 ve F=0.18 olarak tahmin edilmiştir. Araştırma bölgesindeki 0-100 m derinlik katmanında bulunan Kalkanların Eylül-Ekim 1991 tarihleri arasındaki mevcut biyokütlesinin 407.6 ton olduğu ve bu stoktan E=0.37'lik bir yararlanma oranı ile az yararlanıldığı saptanmıştır.
