Abstract :The maturity and fecundity of Squalus acanthias spiny dogfish sampled from the south-eastern Black Sea were studied. Age and length at 50% maturity were 10.49 years and 87.57 cm for males, and 11.99 years and 102.97 cm for females, respectively. Mean biennial fecundity was 19.4 eggs and 12.9 pups. A linear relationship between fecundities and length was found: Fe = 0.09 x TLp + 2.12 (r = 0.5) for pups and Fo = 0.27 x TLp - 21.59 (r = 0.7) for eggs.Keywords : Maturity, fecundity, Squalus acanthias, south-eastern Black Sea
