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].
