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].

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].
