本文以耳石作依据对大亚湾丽叶鲹的年龄和生长进行了研究。报道了其年轮特征、年龄组成、体长与体重的分布;给出了丽叶鲹的体长与体重、体长与耳石长的关系和生长方程;采用重量法求得了180尾雌鱼的怀卵量,并计算了其绝对生殖力和相对生殖力及其与体长和体重的关系;分析了卵径分布、性成熟系数的月变化及幼鱼的生长情况。 In this paper, otoliths as the basis for the study on the age and growth of the leaves of Lydia macrophylla in Daya Bay. The annual ring characteristics, age composition, body length and body weight distribution were reported. The relationship between body length and body weight, body length and otolith length and growth equation were given. 180 females The fecundity of the fecundity was calculated and the relationship between absolute fecundity, relative fecundity and body length and body weight were calculated. The distribution of egg diameter, the monthly variation of sexual maturity and the growth of juvenile fish were analyzed.
