摘要
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。
This paper deals with the age and growth of grey mullet, Mugil cephalus L. collected from fish farms located in Shenzhen and Dongguan of Guangdong Province, in the period 1987-1992. The results thus obtained are as follows:(1) Scale annulus formed mainly from October to January;(2) Relationship between scale radius and body length is: R=0. 009 07L0.776 4;(3) Relationship between body length and body weight is: W= 1. 2716 ×10-5L3. 0695;(4) Relationship between body length and total length is: LT=10.371 1+ 1.180 6LB;(5) Monthly growth curves in body length and weight of one-year-old fish can be expressed by LB=8. 666 9+ 25. 576 9t and W=0.117 0t3.553 0, repectively;(6) Growth rate of this fish up to 5-year-old is computed by using back-calculating method;(7) The von Bertallanffy growth curve parameters derived from the mentioned data are:L∞ = 613. 25mm, K=0. 341 2, t0=-0.825 years, turning point of growth in body weight is: 2. 46 years.
