Abstract

Growth and reproductive parameters were estimated for Scyliorhinus canicula from the south-western Portuguese coast. The sample consisted of 148 specimens with total length ranging from 187 to 580 mm (82 males and 66 females). Maximum ages assigned to males and females were 12 and 13 years, respectively. L and k were estimated as 63.6 cm and 0.16 year for males and 63.2 and 0.15 year for females. Length and age at first maturity were estimated as 42.6 cm and 6 years for males and 44.5 cm and 7 years for females.
