  • 쏨뱅이아목 (Scorpaenoidei) 어류에 속하는 꼼치과 (Liparidae) 어류는 형태적으로 유사하고 오동정 가능성이 크며 체색과 몸의 상대적인 크기 변이가 심하여 분류학적으로도 상당히 혼란스러운 분류군이다. 따라서, 본 연구는 꼼치과 어류의 자원변동을 이해하고 자원관리를 위해 국내 보고된 3속 10종을 대상으로 분자계통 및 분류학적 재검토를 수행하였다. 미토콘드리아DNA COI 영역과 핵DNA RAG2 영역의 염기서열을 이용한 분자계통 분석 결과, 물미거지가 분홍꼼치와 가깝게 유집되는 mtCOI 계통 결과를 제외하면 3속 (분홍꼼치속, 물미거지속, 꼼치속)이 대등한 단계통성을 나타내었다. Gilbert and Burke (1912)는 L. ochotensis와 구분되는 한국산 미거지를 L. ingens로 신종 보고하였으나, 본 연구에서 한국산 미거지는 일본산 및 러시아산 L. ochotensis와 형태 및 분자에서 잘 일치하였으므로 한국산 미거지의 학명을 L. ingens에서 L. ochotensis로 변경한다.

  • Maturity and spawning of the snailfish, Liparis ochotensis was investigated based on samples collected by gill net in the East Sea of Korea from December 2008 to December 2009. The average total length of L. ochotensis was 63.4 cm and 64.1 cm for females and males, respectively. Gonadosomatic index (GSI) began to increase in July, reaching a maximum in November, then began to decrease in December. Monthly changes in the GSI values of L. ochotensis were similar for females and males. Annual reproductive cycle of this species can be divided into five successive stages in females: early growing stage (May), late growing stage (June to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Males show four successive stages; growing stage (May to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Relationship between total length (TL) and fecundity (F) was F=$0.00003TL^{4.002}$ ($R^2$ = 0.703), and F increased with TL. Total length at 50% group maturity was estimated to be 55.8 cm. Our findings suggest that the spawning period takes place from September to December, with the main spawning period occurring from October to December.

  • 쏭뱅이목, Sorpaeniformes의 꼼치과, Liparidae 어류는 남극, 북극, 대서양 및 태평양에 걸쳐 광범위하게 분포하며(Nelson, 1994), 전세계적으로 24속, 317종(Froese and Pauly, 2003), 우리나라에는 2속 7종만이 보고되어 있다(Kim and Kim, 1997). 국내에서는 꼼치과 어류증 꼼치, Liparis tanakae가 식용으로 즐겨 이용되며, 겨울철 남해안에서 주로 어획된다. (중략)

  • A single specimen of Liparis punctulatus (30.9 mm standard length) belonging to the family Liparidae, was collected in the waters off Busan on 4 August, 2016. This species is characterized by a single pair of nostrils, unlike other Liparis species. It is distinguished from L. ochotensis by the numbers of dorsal, anal, pectoral fin rays and the location of the gill opening (above the pectoral fin in L. punctulatus vs. extending ventrally in front of the pectoral fin). In the molecular analysis, 514 bp of 16S rRNA gene of the specimen in this study were identical to that of L. punctulatus from NCBI GenBank (K2P distance < 0.002). This is the first record of the species in Korea based on a voucher specimen, and we follow the Korean name "Kko-ma-kkom-chi" for this species proposed by Myoung et al. and Kim et al.
