鄱阳湖鳡鱼的形态生物学研究

Study on Morphological Biology of Yellowcheek Carp in Poyang Lake

测量分析了鄱阳湖鳡鱼(Elopichthys bambusa)的形态特征和框架特征。鄱阳湖鳡鱼的背鳍为D.Ⅱ.11Ⅰ-9,臀鳍A.0.13,腹鳍V.Ⅰ.9,胸鳍P.Ⅰ.17,尾鳍C.Ⅵ.25。其体长为体高的6.7～6.9倍、为头长的4.3～4.5倍、为尾柄长的6.29～6.31倍、为肠长的2.04～2.08倍。其体长与体重之间的关系可以用幂函数表示,体长与肠长间呈线性关系。

The morphological attribute and framework characteristics of yellowcheek carp （Elopichthys bambusa） in the Poyang Lake were studied in this paper. The results showed that the dorsal fin of yellowcheek carp was D. II. 11 1-9, anal fin was A.0.13, pelvic fin was V. I. 9, pectoral fin was P. I. 17, and caudal fin was C. VI. 25. The ratio of body length to body height, head length, caudal peduncle length, and intestine length was 6.7 - 6.9, 4.3 - 4.5, 6.29 - 6.31, and 2.04 -2.08, respectively. The relationship between body length and body weight accorded with the power function. There was a linear relationship between body length and intestinal length of yellowcheek carp.
