Apoyocotuze theragrae(Trematoda: Aporocotylidae) from the blood vessel of Theragra chalcogramma

명태의 혈관에서 발견한 Aporocotyle theragrae (Trematoda : Aporocotylidae)

Two fully matured specimens were collected from the blood vessel of two fish, Tlreragra chatcogramma, which was bought at the Emun market of Seoul in May, 1985. The blood cuke has no pharynx and suckers. Its body surface was covered with minute spines forming fan-shaped groups, 15 Mm long. The intestine was H-shaped, and the ratio of esophageal length to body length was 1 : 6.1∼6.8. Irregular shaped testes were 109∼114 in number, occupying the intercecal space from cecal bifurcation to the genital pore. The present species was identified as Aporocotyle sheragrae. This is the first report of the species in Korea.

1985년 5월에 서을 이문시장에서 구입한 명태 (Theragra chalcogramma)의 내장 혈관에서 성숙한 2마리의 흡충을 발견하였다. 충체는 홉반과 인두가 없었으며 체표면에 분포하는 가시가 부채꼴 모양의 군을 형성하고 고환의 수가 약 110개인 점, 장이 H자 모양이며, 충난에 난개가 없는 점 등의 형태학적 특징과 문헌적 고찰을 토대로 긴목종ocotyle theragrae로 동정하고 국내 미기록종임을 확인하였다.
