摘要
对2009年5月至2010年4月在爱琴海捕获的boscii Lepidorhombus (Risso, 1810)(四斑megrim)的生长和摄食特征进行了测定。共检测标本1864只，雌雄比例为1:0.41。所有标本的总长度范围为6.3 ~ 34.8 cm，年龄分布为i ~ xiv。Von-Bertalanffy生长方程通过使用每个年龄组的平均总长度来计算。结果表明:雌性(L∞= 43.24 cm, K=0.088, t0= -2.897)， (L∞= 28.53 cm;或25 K = 0;t0= - 0.829)， L∞= 42.9 cm, K=0.097, t0= -2.070)。同时还检测了猪乳杆菌的胃内容物;共鉴定出9个主要类群(Amphipoda、mysidae、Natantia、Anomura、Brachyura、口足目、头足目、Teleostei、Decapod甲壳目)。
Growth and feeding features of the four-spotted megrim Lepidorhombus boscii (Risso,1810) in the Aegean Sea, Türkiye
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.
