【摘要】 对鳓的生长特性和生长过程进行了研究,结果表明:1～5龄的鳓处于生长期;在2龄前生长速度最快,2龄后生长速度减慢。它的生长过程可用特殊的VonBertalanffy生长方程描写。它的生长拐点年龄为2.6龄,在2.6龄时它的体长可达303.03mm,体重为393.38g。更多还原

【Abstract】 The growing feature and process of Llisha elongata were studied.It is showed that Llisha elongata keeps growing during 1～5years old.I t grows faster before 2years old than after 2years old.Its growing process can be described by Von Bertalanffy’ s equation.The age of turning point was calculated to be 2.6.At this age,it will be 303.03mm in the body length and 393.38g in the body weight.更多还原
