Abstract
The growth and feeding features of Lepidorhombus boscii (Risso, 1810) (four-spotted megrim) obtained from the Aegean Sea between May 2009 and April 2010 were determined. During the study, 1864 specimens were examined, and the female/male ratio was 1:0.41. The total length range and age distribution for all specimens were 6.3-34.8 cm and I-XIV, respectively. The Von-Bertalanffy growth equations were calculated by using the mean total lengths of each age group. The results were as follows: (L∞= 43.24 cm, K=0.088, t0= -2.897) for females, (L∞= 28.53 cm; K= 0,.25; t0= - 0.829) for males, and (L∞= 42.9 cm, K=0.097, t0= -2.070) for all specimens. The stomach contents of the L. boscii species were also examined; a total of 9 main groups (Amphipoda, Mysidacea, Natantia, Anomura, Brachyura, Stomatopoda, Cephalopoda, Teleostei, Decapod Crustacea) were determined.
