Abstract

In this study, the growth parameters of the four-spotted megrim, (Lepidorhombus boscii Risso, 1810), were studied in Saros Bay, which had been closed to bottom trawl fishing since 2000. The sex ratio of females to males was 1:0.42. Length-weight relationships were W=0.0032L(3.31) and W=0.0069L(3.04) for females and males, respectively. Growth parameters of the populations were L-infinity=49.8 cm, k=0.09 year(-1)=-2.15 year for females; L-infinity=39.1 cm, k=0.11 year(-1), t(0)=-2.59 year for males. The growth performance index (Phi') was found to be 2.35 and 2.23 for females and males, respectively.
