Abstract

The spermiogenesis and mature spermatozoa of Pseudobagrus fulvidraco were described by means of scanning and transmission electron microscopy. Spermiogenesis is characterized by lateral development of the flagellum, nuclear rotation, deep nuclear fossa formation and compaction into thick granules. The spermatozoa exhibit a round head containing a nucleus that lacks an acrosome, and having a midpiece and a flagellum. The midpiece is small and has a short cytoplasm including several mitochondria separated from the tail by the cytoplasmic canal. The flagellum contains the 9+2 classical axoneme structure and has two axonemal fins. The presence of axonemal fins in the flagellum is a common character in Bagridae. The interrelationships among the Bagridae as well as other teleosts are herein discussed.

한국산 동자개 Pseudobagrus fulvidraco의 정세포변형과 성숙한 정자의 미세구조를 주사 및 투과전자현미경으로 관찰하였다. 정세포변형은 측면에서 발생되는 편모, 핵의 회전, 염색물질로 채워진 핵의 함입과 핵와의 형성이 특징적이었다. 성숙한 정자의 구조는 첨체가 없는 둥근두부와 짧은중편 그리고 긴 편모로 구성되어 있었다. 짧은 중편에는 다수의 미토콘드리아가 있으며 cytoplasmic canal에 의하여 편모와 분리되어 있었다. 편모는 전형적인 9+2 구조이며 axonemal fins를 가지고 있었다. Axonemal fins는 동자개과에서 공통적으로 나타나는 형질로 여겨지며 그 외 다른 특징을 경골어류에서 비교하였다.
