鲮鱼鳞片可作为年龄鉴定的依据。鳞片新年轮逐月出现率的变化,表明年轮形成主要在3～10月份。计算出鳞片与体长,体长与体重的关系式。3龄以前属于幼鱼生长阶段,体长和体重的相对增长率较大;3 龄以后则进入成鱼生长阶段。其生长适合于 von Berta-lanffy 生长方程,体重生长曲线拐点位于 15.55龄,应属衰老拐点。其生长速度和加速度曲线能反映生长过程的变化特点。渔获物组成以性未成熟个体为主。限制捕捞3~+龄以下的个体,有利于渔获量稳定和扩大繁殖群体。
Scallop scales can be used as the basis for identification of age. The change of emergence rate of new annual rings of scales shows that the formation of annual rings is mainly from March to October. Calculated scales and body length, body length and weight of the relationship. Before the 3rd instar, it belonged to the growth stage of juveniles, and the relative growth rate of body length and body weight was larger; after 3 years of age, they entered the stage of adult fish growth. Its growth is suitable for von Berta-lanffy growth equation. The inflection point of body weight growth curve is located at 15.55 years old, which should belong to the inflection point of aging. The growth rate and acceleration curve can reflect the changing characteristics of the growth process. Catches are mainly immature individuals. Restrictions fishing individuals under the age of 3 ~ +, is conducive to the stability of catch and expand the breeding population.
