연구는 갈치 Trichiurus lepturus의 성 성숙과 생식생물학적 기초 정보를 제공하기 위해 수행하 였다. 난자형성과정 동안 난모세포와 핵의 크기는 증가하였으나 핵에 대한 인의 비율은 감소 하였다. H-E 염색 결과, 세포질의 염색성은 호염기성에서 호산성으로 변하였다. 난황형성개시 기 난모세포의 난경은 약 63.2 (±12.7) μm였다. 세포질에서는 호산성의 난황핵이 관찰되었다. 성숙기 난모세포의 난경은 216.6 (±24.7) μm였으며, GVBD (germinal vesicle breakdown)가 관 찰되었다. 완숙기 난모세포의 난경은 317.9 (±80.9) μm였으며, 방사대의 두께는 4.2 (±1.7) μm 였다. 난모세포의 발달형태는 난군동기발달형에 속하며, 난황 축적은 대부분의 경골어류와 마 찬가지로 외재적 방법과 내재적 방법에 의한 것으로 판단되었다.
This study was conducted to provide basic information on the sexual mature and reproductive biology of Trichiurus lepturus. During the oogenesis, size of oocyte and nucleus showed the increase tendency but size ratio of nucleolus to nucleus was decreased. In the result of H-E stain, the stainability of the cytoplasm was changed from basophilic to eosinophilic. The egg diameter of initial vitellogenic oocyte was about 63.2 (±12.7) μm. In the cytoplasmic cortex, eosinophilic yolk nucleus was observed. The size of mature oocyte was 216.6 (±24.7) μm and GVBD (germinal vesicle breakdown) was observed. The size of ripe oocyte was 317.9 (±80.9) μm and the thickness of zona radiata was 4.2 (±1.7) μm. The oocyte developmental type is considered to belong to the group synchronous type. The accumulation of yolk in the oocyte, like most teleost, is thought to be of two types: exogenous and endogenous accumulation.
