研究池养条件下鲻鱼MugilcephalusLinnaeus的年龄和生长特性,结果表明,鳞片新年轮主要在10—1月出现;鳞长与体长关系式为:R—0.00907L(0.7764);I—V龄鱼体长和体重相对生长率和生长指标随着年龄增长而逐渐下降;体长与体重关系式为:W=1.2716×10(-5)L(3.0695),体长与全长关系式为:LT=10.3711+1.1806LB,当年鱼体长和体重生长与月龄的关系分别为:LB=8.6669+25.5769t,W=0.1170t(3.5530),vonBertallanffy生长参数L∞=613.25mm,K=0.3412,t0=-0.825,体重生长拐点值为2.46a。
The age and growth characteristics of Mugilcephalus Linnaeus were studied under pond culture conditions. The results showed that the new ring of scales appeared mainly in October-January. The relationship between scale length and body length was R-0.00907L (0.7764) The relative growth rate and growth index of body length and body weight of V-shaped fish decreased gradually with age. The relationship between body length and body weight was W = 1.2716 × 10 (-5) L (3.0695) The total length of the relationship was: LT = 10.3711 + 1.1806LB, the relationship between body length and body weight and age were LB = 8.6669 + 25.5769t, W = 0.1170t (3.5530), vonBertallanffy Parameters L∞ = 613.25mm, K = 0.3412, t0 = -0.825, weight growth inflection point value of 2.46a.
