Marmara Denizi’nde benekli kedi balığı, Scyliorhinus canicula [L.]’nın hepatosomatik indeksi, üremesi, boy-ağırlık ilişkisi

Abstract

91 benekli kedi balığı, Scyliorhinus canicula (L.)’nın bazı biyolojik özellikleri incelenmiştir. Örnekler 2013-2014 yıllarında Bandırma Körfezi’nden trol çekimleri ile yakalanmıştır. Balıkların toplam boyları 18,0-47,4 cm, ağırlıkları ise 28,78-583,78 gr. arasında olup, boy-ağırlık ilişkisi allometrik olarak arttığı gözlenmiştir. Eşey oranı 1.12:1 olup, istatistiksel olarak önemli bulunmamıştır (p>0.05). Olgun dişilerin her batında ardı ardına en az iki yumurta bıraktıkları belirlenmiştir. Hepato-somatik değerlerinin erkek ve dişiler arasında önemli farklılıklara sahip olmadığı hesaplanmıştır [p>0.05].

Length-Weight Relationships, Reproduction, Hepatosomatic Index of The Lesser Spotted Catshark, Scyliorhinus canicula [L.] The Sea of Marmara, Turkey

Abstract

Some biological aspects of 91 lesser spotted catshark Scyliorhinus canicula [L.] were examined. The samples were caught with trawl hauls from Bandırma Bay in the years of 2013-2014. Total lenghts of fishes ranged from 18.0-47.4 cm while their weights ranged from 28.78-583.78 g. It was observed that lenght-weight increased allometrically. As the overall sex ratio [male and female ] was 1.12:1, it was not found statistically significant [p>0.05]. The mature females were determined to spawn successively at least two eggs each batch. HSI values were estimated not to have significant differences between males and females [P>0.05].
