Abstract
In this investigation, the growth and feeding characteristics of Galeus melastomus Rafinesque, 1810 and Squalus blainvillei (Risso, 1826) distributed in Sığacık Bay were examined. 130 (59♂, 51♀, 20 juvenile) individuals of Galeus melastomus were examined and the minimum, maximum and mean of total length were determined as 9 cm, 19 cm and 14,01±1,96 cm respectively. Beside that minimum, maximum and mean of total weight were 2,92 g, 22,67 g and 8,46±4,03 g respectively. 135 (57♂, 78♀) individuals of Squalus blainvillei were examined and the minimum, maximum and mean of total length were determined as, 16 cm, 28 cm and 21,46±2,21 cm respectively. Beside that minimum, maximum and mean of total weight were 18,64 g, 95,92 g ve 45,64±15,97 g respectively.The mean food of two species of dogfish were Crustacea species, followed by the species of Teleostei and Cephalapoda.
