采用传统的形态学和解剖学方法,对条斑星鲽(Verasper moseri)人工种鱼的外部形态特征及内部组织器官进行了系统的观测和描述。结果表明:比例性状体长为体高的1.67~2.01 倍、为头长的3.47~3.90 倍;头长为头高的1.07~1.49 倍,为吻长的5.11~8.18 倍,为眼径的4.60~6.33 倍,为眼间距的11.3~14.3 倍;尾柄长为尾柄高的0.51~0.63 倍;可数性状背鳍、臀鳍、腹鳍、胸鳍、尾鳍鳍条数分别为75~80、53~56、6、12、19;侧线鳞数88;食道粗短,胃发达且分化明显,肠在腹腔内呈一个盘曲,比肠长(肠长/体长)为0.55~0.64,以上表明条斑星鲽为典型的肉食性鱼类;成熟雌鱼两卵巢形态不对称,其中无眼侧略大;一对“矢耳石”呈椭圆形,薄而透明,对向排列。 |

Abstract: |
The result shows the following data:depth, 1.67~2.01; head, 3.47~3.90 in length to base of caudal; depth of head, 1.07~1.49 in its length; the ratios of head length to snout length, eye diameter and interorbital width were 5.11~8.18, 4.60~6.33 and 11.3~14.3, respectively; and other parameters are as follows: depth of caudal peduncle, 0.51~0.63 in its length; dorsal 75~80; anal 53~56; ventral 6; pectoral 12; caudal 19; lateral line scales 88. The digestive tract consisted of clearly distinguishable oesophagus, stomach, intestine and rectum; the intestine twisted one time and the relative length was 0.55~0.64. The morphology of the digestive tract was consistent with the specie’s flesh-food habits. |
