本文对两种台湾先雄两性鲷科超微结构上，这四个物种的精子有一个球形的，均匀的电子致密的核与轴向核窝。中段包含1至4个球形线粒体，环绕鞭毛的基体。四种鱼的成熟精子均为原始精子或外胚囊型精子，符合硬骨鱼1型精子，鞭毛轴插入垂直于核窝内侧。这四种鲷科鱼类的核窝深度和线粒体数量的变化很大。本研究为鲷科比较精子学的研究提供了有用的系统特征。(c)2004爱思唯尔有限公司保留所有权利。
The mature spermatozoa of two Taiwan protandrous hermaphrodite Sparidae Acanthopagrus berda and Acanthopagrus australis are investigated and compared with those of other two Sparidae (Lagodon rhomboids and Archosargus probatocephus) from the Western hemisphere. Ultrastructurally the spermatozoon of these four species has a spherical, homogeneously electron-dense nucleus with an axial nuclear fossa. The midpiece contains one to four spherical mitochondria and encircles the basal body of the flagellum. The mature spermatozoa of the four species are of the primitive or ect-aquasperm form and conform to the teleostean type 1 spermatozoon with the flagellar axis inserts perpendicular and medial to the nuclear fossa. Variation in the depths of the nuclear fossa and rnitochondria number is substantial in these four Sparidae species. This study provide useful systematic characters to the existing knowledge of comparative spermatology of Sparidae. (c) 2004 Elsevier Ltd. All rights reserved.
