短吻舌鳎生长特性的研究

用多元统计分析方法对短吻舌鳎的生长规律、生长特性及雌雄之间的生长差异进行了研究。结果表明：1-4龄的短吻舌鳎处于生长期。在生长速度上，1-2龄生长速度最快。以后生长速度逐渐减慢；在生长方式上，1-2龄体长、体高、体厚的生长基本同步，3龄，体高、体厚生长更快，到4龄。以体厚生长最快；生长方式不同，使不同年龄鱼的体型不同。3-4龄鱼比1-2龄更宽厚；在同一年龄组中，雄鱼不仅显著地小于雌鱼，而且比雌鱼更细长、侧扁，用多项式来描写短吻舌鳎的生长过程，并求出生长拐点年龄为2．35龄。

Study on the Growing Feature of Cynoglussus Abbreviatus

The growing regularity, growing feature and difference on the growth between male and female of Cynoglussus abbreviatus are studied by the means of multivariate statistical. Cynoglussus abbreviatus of 1~4 years old are on the growing stage with the fastest growing speed at the age of 1~2, it being gradually getting slow after 2 years old . Its growth on length, body height and body width is synchronous before 2 years old and it's body height and body width grow faster at the age of 3, with the fastest growing speed on body width at the age of 4. The body shape varies in different ages, being wider and higher at the age of 3-4 than at the age of 1-2. Compared with female , male is smaller and thinner. The growth model of Cynoglussus abbreviatus is built in polynomial and the inflection point of the curve is 2.35.
