| 摘 要： | 通过扫描电镜对黑鲷，牙鲆和红鳍东方豚成熟卵膜进行比较研究，认为其卵径大小，壳膜厚薄，微型孔小管长短，孔径大小，分布密度，卵膜孔和卵孔管等形态都存在着种的差异，尤其是由漏斗状壁的前庭和漏斗底的卵孔管两个主要部分组成的卵膜孔也体现了种的特异性。黑鲷是深凹陷，短孔道型，牙鲆是浅凹陷，短孔道型，红鳍东方豚是无漏斗状凹陷，仅有一长孔道型的卵孔管和簇拥其周围众多乳突等的特殊结构，这３种鱼的卵孔管内壁肯螺纹，属

| Abstract: | The morphology of mature eggs of Sparus macrocephalus, Paralichthys olivaleus and Takifugu rubripes was observed and compared by scanning electronic microscope in this study. Differences existed among the three species in the size of the eggs, the thickness of the chorions, the length, diameter and distribution of the micropylar canals, the shapes of pore canal and micropyle, etc.. The micropyles composed mainly of funnelake and micropylar canal expressed the specific property of species. The micropyle is deeply sunken with a short tunnel in Sparus maerocephalus, but shallow sunken with a short tunnel in Paralichthys olivaleus. Takifugu rubripes has no funnel-shaped hollow, the micropyle is just a tunnel surrounded by a group of papilla. The inner wall of the micropyle in all three species is spiraled. |
