摘要
对７种鲤科鱼类（草鱼、青鱼、鲢鱼、鳙鱼、团头鲂、鲤鱼、银鲫）采用剪断背鳍软条的方法作标志，约２个月后伤口处形成一节瘤状突起。根据组织学观察，瘤状突是一个坚硬的骨头，鱼经６１４天饲养，该标志性硬突不会消失。
Seven species of Cyprinidae fishes ( Ctenopharyngodon idellus, Mylopharyngodon piceus, Hypophthalmichthys molitrix, Aristichthys nobilis, Megalobrama amblycephala, Cyprinus carpio, Carassius auratus gibelio ) was marked by cutting the soft rays of dorsal fins and a hard bulge was formed on the cutting. The bulge was found as hard bone base on histological observation, and would not disappeare even after the marked fish was reared for 614 days.
