| 摘要: |
| 在现代生物科学中,应用生物卵壳亚微结构的物种特异性进行分类研究已成为可行性现实。在海洋生物学研究中,曾发现海胆类未受精的卵壳层颗粒中即存在着眀显的物种特异性差别( L?nning,1967)。很多学者通过对鱼类卵细胞发生期间的亚微结构及卵壳形成的研究,证实在鱼类卵壳结构中亦存在特异性的种间差异,并认为这些差异与分类学、生物学及其区系分布有密切关系( Müller& Sterba,1963; Yamamoto,1963;G?tting,1966; Anderson,1967; Flügel,1967)。目前我国对鱼类卵壳( Egg chorin)结构的研究还鲜为人知,本文亦是首次通过对12种海洋经济鱼类受精卵的卵壳结构差别的探讨,为进行鱼类系统分类和系统发育研究提供科学依据。 |

| Abstract: |
| Naturally fertilized eggs collected from the Bohai Sea and the Yellow Sea and areificially fertilized eggs were observed under TEM, 12 species were selected from the samples for comparative study of their chorion structure. The difference of chorion thickness and division of chorion layers show the species specific difference of fish eggs. |
| Key words: MARINE FISHES, ULTRASTRUCTURE OF THE CHORION |
