两种珍稀鱼类的形态学和生态学的补充研究

通过形态学比较研究和饲养生态学的观察，作者补充了细刺鱼牙齿结构特征和条石鲷的体色、鳍色的形态学特点，探讨了这两种鱼类的生态习性和１９９８ 年在青岛海域出现的原因。进行２～３ 个月的饲养实验后，得到细刺鱼月均增长量为１０．３％ ，条石鲷为１４．６％ 而明显高于同池饲养六线鱼的结果。鉴于两种鱼类彩色艳丽、游姿优美，具观赏价值，为此建议可将这两种鱼作为海水养殖或观赏鱼类的实验对象

A Supplementary Study on the Morphology and Ecology of Two Species of Rare Fish from Qingdao

By the studies on the morphological comparsion and the observations of aquacultural ecology in detail, the authors supplement the teeth structure characters of Microcanthus strigatus and the morphological characters of body colour and fin colour of Oplegnathus fasciatus. Extensive investigations have been made of the ecological habit of these two species and the reason for their emergence in the Qingdao area in 1998. After rearing of two to three months, the average monthly growth rate of Microcanthus strigathus and Oplegnathus fasciatus is 10.3% and 14.6% respectively, notably higher than that of fishes belonging to the Hexagrammos genus in the same pond. Because of their beautiful colours and elegant swimming posture, they are very popular. Therefore we suggest that they should be made experimental species in marine aquaculture.
