| 摘 要： | 2010年在广东省饶平县柘林湾进行了七带石斑鱼（Epinephelus septemfasciatus）海水网箱人工养殖研究,观察和研究了人工养成的七带石斑鱼的形态特征和生物学性状。通过观察、测量、解剖,对114尾七带石斑鱼的外部形态、可量比性状和内部结构进行了研究。结果表明,七带石斑鱼体呈椭圆形,侧扁,体侧具7条褐色横带,第1条横带仅伸达主鳃盖骨上方边缘,第6条横带分成2条,体侧横带具有不规则的白色斑纹,各鳍边缘白色,背鳍鳍棘部褐色和白色横带相间,鳍条部具有由白色横带延伸而成的3个白斑。胃呈卜型,幽门盲囊发达;肠道长度为体长的0.7～1.4倍,与七带石斑鱼为肉食性鱼类的特征相一致。

| Abstract: | We cultured 114 sevenband groupers （Epinephelus septemfasciatus） in net cages in the open waters of Raoping County in Guangdong Province to investigate the morphological and biological characteristics, especially the external morphological characteris- tics, qualitative traits and internal structure. The results show that E. septemfasciatus is elliptical and compressiform with 7 brown cross bands. The first band merges with upper edge of preopercle and the sixth band divides into 2 bands. Some irregular white stripes are in the body side band. The edges of all fins are white. Brown and white stripes are alternate in the dorsal fin spine. Three pale interspaces are below the dorsal fin ray. The stomach is ＂ shaped and pyloric caeca is strong. The intestine length is 0.7 time to 1.4 times of body length, which matches the characteristics of predacious fish. |
