| 摘 要： | 文章采用阿利新蓝-茜素红双染色法对孵化后第1～第18天卵形鲳鲹（Trachinotus ovatus）仔稚鱼尾骨骨骼发育进行了系统研究。研究表明,孵化后第18天卵形鲳鲹尾部骨骼分化为尾下骨（Hy）、尾上骨（Ep）、尾下骨旁骨（Phy）及尾神经骨（Urn）。孵化后第7天,仔鱼尾部出现第1片尾下骨（Hy1）。孵化后第9天,Hy1与Hy2及Phy在尾部同时出现。孵化后第9～第15天,伴随着Hy3和Hy4的出现,脊索矿化接近尾区,同时脉棘（Mhs）和髓棘（Mns）相继出现。孵化后第15天,3片Ep已经完全分化出来。孵化后第15～第18天,Hy5在尾部分化出来,且各骨片轮廓变清晰。文章探索了卵形鲳鲹胚后发育过程中尾部骨骼发育的特征,为卵形鲳鲹骨骼发育研究奠定了基础。

| Abstract: | We investigated the skeletal ontogeny of Trachinotus ovatus larvae of 1 ~ 18 dph by using double staining technique. Results indicate that： on 18 dph, the caudal skeletons of T. ovatus consisted of hypurals （Hy）, epurals （Ep）, parhyurals （Phy） and uro- neural （Urn） near the urostyle. On 7 dph, the first hypural （ Hyl ） appeared in the caudal area （CA）. Hy1, Hy2 and Phy appeared at the end of urostyle on 9 dph. On 9 ～ 15 dph, with the appearance of Hy3 and Hy4, ossification approached to CA, and modified haemal spines （Mhs） and modified neural spines （Mns） appeared simultaneously. On 15 dph, the Eps of fish fully developed. On 15 ～ 18 dph, Hy5 formed next to Hy4, and the outline of each skeleton becomed observable. This study explored the morphological characteristics of caudal skeletal ontogeny in larval T. ovatus, which provides fundamental information for future researches on skeletal development of T. ovatus and other similar species. |
