  • 1986년부터 1991년까지 우리나라 연안에서 채집된 베도라치아목 Blennioidei과 등가시치아목 Zoareoidei의 어류 표본을 대상으로 분류학적으로 재검토하였다. 베도라치아목 어류는 먹베도라치과 Tripterygiidae의 가막베도라치 Enneoptewgius etheostomus(Jordan et Snyder) , 비늘 베도라친과 Labrisomidae의 비늘베도라치 감eoclinus bwope(4ordan et Snyder) , 그리고 청 베도라치과 B1enniidae의 청베도라치 Pictiblennius yotobei(Jordan et Snyder), 저울베도라치Entomacrodus stellifer lighti(Herre), 대강베도라치 Istibfennius enosimae(Jordan et Snyder), 앞동갈베도라치 Omobranchus elrgons(Steindachner), 골베도라치 O. punctatus (Valenciennes) 및 두줄베도라치 Petroscines breuiceps(Valenciennes)의 7속 8종으로 분류되었다. 이 가운데 N. bwope의 표본은 우리나라에서는 본 조사기간 중 제주도 연안에서 처음으로 확인되어 한국 미기록종으로 보고한다. 한편 등가시치아목의 어류는 등가시치란 Zoarcidae의 벌레문치 Lycodes tanakoi Jordan et Thompson, 먹갈치 Lycodes nakamurai Tanaka, 등가시치 Zoarces gilrii Jordan et Starts, 실베도라치 Zoarchias aculeatus( Basilewsky), 우베도라치 Zoarchias uchidai Matsubara, 민베도라치 Zoarchias glaber Tanaka, 얼룩가시치 Neozoarces pulcher Steindachner, 칠성갈치 Petroschmidtia toyamensis Katayama, 자갈치 Gvmnelopsis brashnikoui Soldatov, 문자갈치 Dauidijordania poecilimon(Jordan et Fowler) 및 청자갈치 Allolepis hollandi Jordan et Hubbs, 장갱이란 Stichaeidae의 세줄베도라치 식nogrammus hewagrammus(Temminck et Schlegel), 장갱이 Stichaeus grigorjemi Her\ulcornerenstein, 왜도라치 Chri'olophis wui(Wang et Wang ) , 괴도라치 Chirolophis joponicus(Jordan et snyder) , 벼슬베도라치 각ectrias benjamini Jordan et Snyder, 가시베도라치 Lumpenella nigricons Matsubara, 육점날개 Ophistocentws zonope jordan et Snyder, 그물베도라치 Dictyosoma burgeri Van der Hoeven 및 황점 베도라치Dictyosoma wbrimaculata Yatsu, Yasuda et Taki, 그리고 황줄베도라치란 Pholididae의 황줄베도라치 Phoris taczanowskii(Steindachner), 오색베도라치 Phoris omotus (Girad), 베도라치 Pholis nebuloso(Temminck et Schlegel), 횐베도라치 Pholisfangi(Wang et Wang) 및 점베도라치 Pholis crossispino(Temminck et Schlegel)의 17속 25종이 분류되었다. 이중에서 Zoarchias glaber, Chirofophis oui, Alectrias benjamini, Dictyosoma mbrimaculamia 및 Pholis crassispina의 5종은 한국 미기록종으로 보고한다. 아울러 이들 미기록종을 포함한 한국산 베도라치아목과 등가시치아목 어류의 속 .종 검색선 와 종별 사진을 제시하고, 이들 표본을 근거로 하여 형태적 특징, 계수계측치, 채집지 및 서식처를 기록하였으며, 이들의 분류학적 위치에 대해 논의하였다. 우리나라에 출현하는 베도라치아권의 어류는 거의 대부분이 제주도 연안과 서남해 연안에 제한분포하는데, 등가시치아목의 어류는 주로 동해연안에서 많은 종이 출현하고 있어서 동물지리학적으로 주목된 다.

Tongue-like Warm Water Appeared in the East Entrance of the Jeju Strait (제주해협 동쪽 입구에 출현하는 설상의 난수)

  • A tongue-like warm water which is a part of the Tsushima Warm Current appears whole year around in the east entrance of the Jeju Strait. Because of this warm water, the current direction flowing into the Jeju Strait from its west area seems to be changed in the Jeju Strait. Therefore the intermediate and bottom water of the Jeju Strait may greatly influence the formation of the coastal water in the South Coast of Korea. Since this tongue-like warm water is stronger in winter than in summer in its formation, Tsushima Warm Current comes closer to the South Coast of Korea in winter and its north boundary frequently approaches close to the coast of Geomun Island and Sori Island.

  • We studied the fishing ground of a yellowtail and oceanographic conditions around Chujado and Marado around Jeju Island from autumn to winter. Also we investigate the forming mechanism of fishing ground around Marado, which shows the best catch of yellowtail near Jeju island. The obtained results are summarized as follow ; 1. When the high temperature water about 15.0∼19.0 in depth of 50m distributed around Chujado and Marado, the fishing ground of Yellowtail is shows a good catch. On the contrary, when the low temperature water about 11.0∼14.0 is shows a poor catch. 2. Fishing grounds of yellowtail by handline fishing are formed with a school of Yellowtail migrating southward from the coastal sea of Korea and slaying around Marado to winter and spawn due to following factors. Firstly, a front of temperature and salinity is formed between inshore water and oceanic water around Marado. Secondly, small-size eddies and excellent horizontal and vortical mix which is created by strong tide and geographical features including irregular underwater ground and an isolated island. An abundant school of yellow tails stays in front of the tide where a good fishing ground was made.

  • For the determination of coastal environmental contamination level of benomyl, benzimidazole pesticide, the residue of benomyl in various environmental samples on the Cheju island was monitored in May, August and October 1996, respectively. The residue of benomyl was determined as carbendazim because benomyl was converted to carbendazim (methyl 2- benzimidazolecarbamate) in the environment. The qualified limit detection of benomyl was $0.2{\mu}g/L$ in ocean water and $0.4{\mu}g/kg$ in the solid such as sediment and sea organism by HPLC with UV detector. Benomyl was not detected in any water and sediment. Moreover benomyl was neither detected in seaweed cava(Ecklonia Cava), agar(Gelidium amansii), turban sell(Batillus cornutus) and sea urchin(Anthocidaris Crassispina). Above date suggest that the benomyl used in the Cheju island is not the major source of coastal contamination.

  • Based on three specimens (50.6~67.7 mm SL) collected from the southern coastal waters of Jejudo Island, Oxycheilinus bimaculatus was described as the first record from Korea. They were characterized by having two small dark spots behind eye on head and body posterodorsally, a rhomboid caudal fin with elongated central rays and produced uppermost ray as a filament in terminal male, six predorsal scales, and two scale rows on cheek. We proposed a new Korean name, "Du-jeom-gin-ju-dung-i-nol-rae-gi", for the species referring to having two dark spots on head and body.
