摘要
本文对洈水水库鳡鱼的生长及其利用进行了分析研究,结果表明:1.该种鱼生长快,高速生长时间长,可连续5年每年生长6kg以上;2.雌、雄鱼体长与体重生长分别适合Von.Bertalanffy的生长公式:L=L_∞(1-e-k(t-t·))和W=W_∞(1-e-k(t-t·))~3;3.雌鱼体重生长速度快于雄鱼,体长生长无明显差别;4.建议大中型水体中的鳡鱼与其它鱼类群落体重之比控制在3—5％为宜。
This paper deals with the growth of E. bambusa and its utilization in fisheries in Weishui Reservoir, Hubei province. The results abtained are as follows:1. The growth condition of E. bambusa in Weishui Reservoir is very well.The high speed growth lasts five years at a growth rate of more than 6 kg per year.2. The growth by length and weight of E .bambusa from this reservoir may be expressed well by using of Von. Bertalanffy's equation as L=L∞(1-e-κ(t-t0 ) and W = W∞(1 -e-κ(t-t0)) respectively.3. The growth by weight of the female is faster that of the male,but no difference have been found in the length growth between the female and male.
