In this study, the growth parameters of four-spotted megrim, (Lepidorhombus boscii Risso, 1810), were studied in Saros Bay, which had been closed to bottom trawl fishery since 2000. The sex ratio females males was 1:0.42. Length-weight relationships W=0.0032L3.31 and W=0.0069L3.04 for males, respectively. Growth populations L∞=49.8 cm, k=0.09 year-1, t0=-2.15 year females; L∞=39.1 k=0.11 t0=-2.59 males. performance index (Φ') found be 2.35 2.23
