| 摘 要： | The surface ultrastructure of mature egg chorion of the tamed northern sheatfish Silurus soldatovi in Hei- longjiang river was investigated by scanning electron microscopy. The outermost layer was composed of a thin lamella of a jelly coat. The surface of ielly coat was characterized by overlapping net-like fibrillar lamellae, many clefts with bridges and pores. The pore canals were 0.25 μm in diameter. The pore density was about 0.7 - 1.0/μm^-2. The pores on the surface of jelly coart were distributed uniformly. Mature eggs of sheatfish possessed a funnel-shaped micropyle in the animal polar region. The micropylar region was about 0.04 mm^2 area in diameter with 3 - 8 ridges in radial arrangement. Fertilized eggs in which jelly coats were removed mechanically presented no adhesiveness and exhibited inlays of irregular granules on their surface [Acta Zoologica Sinica 51 （5）： 940-946, 2005]. |
