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.

Seasonal variation in species composition and abundance of fish assemblage in the north coast (NC: Ayajin) and central coast (CC: Hupo) of the East Sea were calculated using samples collected by trammel net during 2011-2012. A total of 20 species from NC and 17 species from CC were collected. Of the fishes collected, the dominant fish species were Glyptocephalus stelleri and Careproctus rastrinus in the NC, and Dasycottus setiger and G. stelleri in the CC. These 2 fishes accounted for 71.7% and 81.0% of the total number of individuals collected in the NC and CC, respectively. The number of fish species, number of individuals, biomass and species diversity indices fluctuated with the seasons. The cluster analysis and non-metric multidimensional scaling (MDS) based on Bray-Curtis similarity revealed that the fish assemblages classified into north and central groups. Analysis of similarity percentages of species contributions (SIMPER) indicated that most individual of G. stelleri and Gadus macrocephalus contributed to north group, and D. setiger and G. stelleri in central group, whereas 15 species contributed to 90% of the dissimilarity.

The investigation for the species composition and catch in the deep East Sea was carried out with commercial trawlers from 2004 to 2006. The catches were 6,043kg and were composed of 43 species with 34 hauls between 250m and 1,030m in depth. The principal species caught were Allolepis hollandi, red crab (Chionoecetes japonicus), Careproctus rastrinus, Argis lar, Chionoecetes opilio, Malacocottus gibber, Petroschmidtia toyamensis, Pandalus eous Makarov, and Dasycottus setiger. The rate of discarded catches in situ was about 50%. The diversity indexes of 2005 and 2006 were 1.152 and 0.878, respectively, and the evenness indexes at those years were 0.752 and 0.583, respectively, which implied one dominant species caught in 2006.
