摘要
Abstract
The postembryonic development of Cyphnus multitaeniata Pellegrin et Chevey can be divided into three periods (early larva, late larva and juvenile) and 11 stages based on morphogenesisas and development features. Compared with other Cyprinoid fish, the postembryonic development of Cyprinus multitaeniata has certain kinds of characteristics such as rapid exhaust of yolk sac and fast growth of air bladder (building of patrol swimming), emergence and development of scales in early stages, etc. The whole postembryonic development can be finished in a relative short time. Under the water temperature of 25.0±0.7°C, larvaes upon hatching with body length of 5.2±0.2mm can grow up to 20.6±0.3mm in length after 24-to-26-day postembryonic development. Relationship of body length and age is a positive linearly correlationduring the whole development. The related equation is L = 5.8591 + 0.6254 A (r=0.9992, P＜0.01), with an approximated growth rate of 0.63mm per day. Proposals for fry cultivation based on the above mention researches were also put forward.关键词
