In this paper, we studied some biological aspects of big eye scad () from Maldives. The fish sample was collected from the local fish market at Bangaa Faru, Male, Maldives. The length of the samples were ranged from 7.7 cm to 24.5 cm (mean value = 16.85 ± 2.82 cm) in fork length. Body weight ranged between 8 g to 255.6 g (mean value = 87.76 ± 40.41 g). The exponent values (b slope) of lengthweight relationship of are 2.9838 for females and 2.7687 for males; indicating negative allometric growth pattern for both sexes. Synchronous reproductive behaviour was observed in both sexes and a pronounced peak of Gonadosomatic index was observed in females in January 2013. It is estimated that length at first maturity (L) for females is at 19.39 cm FL and for males at 21.76 cm FL. Our result also suggest that big eye scad have a reduced swimming capability, resulting the species to be easily caught. Careful planning and management should be implemented to prevent the big eye scad from being overfished.
在本文中，我们研究了来自马尔代夫的大眼鲹（）的一些生物学特性。鱼样本采自马尔代夫马累班加阿法鲁的当地鱼市。样本的叉长范围为7.7厘米至24.5厘米（平均值 = 16.85 ± 2.82厘米）。体重在8克至255.6克之间（平均值 = 87.76 ± 40.41克）。大眼鲹的体长 - 体重关系指数值（b斜率），雌性为2.9838，雄性为2.7687；表明两性均呈负异速生长模式。观察到两性均有同步繁殖行为，并且在2013年1月雌性的性腺指数出现明显峰值。据估计，雌性首次成熟体长（L）为19.39厘米叉长，雄性为21.76厘米叉长。我们的研究结果还表明，大眼鲹的游泳能力下降，导致该物种易于被捕捞。应实施精心规划和管理，以防止大眼鲹被过度捕捞。
