| 摘 要： | 对2007年取自粤西水域的福建纹胸鮡进行生物学研究。结果显示:粤西福建纹胸鮡食性是以动物性食物为主;雌雄性比为1.16∶1;性腺成熟系数雌性为0.263%～19.048%,雄性为0.101%～3.226%;福建纹胸鮡个体绝对怀卵量在45～420粒之间,平均140.9±74.7粒;相对怀卵量在31.7～130.4粒/g之间,平均64.3±21.1粒/g;绝对怀卵量与体长呈幂相关:y=0.0008 x7.7308,R2=0.855 2;绝对怀卵量与体重呈指数相关:y=14.439 e0.838 2 x,R2=0.878 3。 |

| Abstract: | The biological study of Glyptothorax fukiensis which were captured in the waters of the western Guangdong in 2007 was carried out.The results showed that: The food habits of Glyptothorax fukiensis was inclined to be carnivorous;The sex ratio of female to male is 1.16:1 and the maturity of ovary was between 0.263% to 19.048% while that of male sex gland was between 0.101% to 3.226%;The absolute brood amount(ABA) of Glyptothorax fukiensis was between 45 ane 420 grains with a average of 140.9±74.7 and the relative productivity was about 31.7 to 130.4 grains per gram body weight with a average of 64.3±21.1;The ABA and body length was to be power related that can be formulated as y = 0.000 8 x 7.730 8,R2 = 0.855 2 and the correlative between ABA and body weight was to be exponential that can be formulated as y = 14.439 e 0.838 2 x,R2 = 0.8783. |
