Abstract

An investigation was carried out to obtain basic information needed to develop methods for artificial propagation and conservation of the mottled skate Raja pulchra, an important food resource in western Korea that has declined from overfishing. In this paper we provide evidence of multiple spawning and describe properties of the ovary, and morphology of the egg capsule and the fully-formed offspring. The vitellogenic follicles in the ovary was $179.8{\pm}57.1$ (54~247) and can be classified into five size groups, which the last group of ova are considered as the moving to the capsule gland where fertilization and encapsulation of ova take place. The morphology of the egg capsule of R. pulchra is unique among the species of the family Rajidae and showed multi-embryo characteristics, having two to six yolks in each capsule. The adaptive morphological changes of larvae developing inside the egg capsule are described based on specimens extracted from the capsule.

참홍어(Raja pulchra)는 서해지역에서 산업적으로 활용도가 높고 개체군 크기의 축소가 예상되므로 인공증식 기술 개발과 보존을 위해 일련의 연구를 수행하였다. 이 연구는 연중 대형 난각의 형태로 다회 산란하는 특성과 완전한 형태로 부화하는 치어의 특징을 기록하였다. 난소 내 난은 평균 179.8 (54~247)개로 직경이 5가지 무리로 구분되어 순차적인 산란에 기여하는 특성을 보였다. 난각은 다른 홍어류의 종과 구분되는 특징적 구조를 보였으며, 하나의 난각내에 포함되는 배의 수는 2~6개 범위이었다. 아울러 난각내에서 발생하는 자어와 부출 직전에 해당하는 치어의 형태적 특징 및 변화를 분석하여 기술하였다.
