제주연안은 태풍 및 겨울철 북서풍의 영향으로 일부 항만 내를 제외하고는 가두리가 극미한 실정으로서 광활한 바다의 능동적인 이용을 위하여 해양수산부(해양수산 개발원)의 특정연구개발사업의 일부 지원을 밭아 연구를 수행하였다. 외국의 사례를 보면 북대서양연안의 극심한 해양환경(파고 20m)을 고려한 TLC(Tension Leg Cage) 시스템을 노르웨이 Marintek에서 개발하였으며[1], 일본의 경우는 수심이 깊고 만이 많은 해역을 고려한 부침식 전복 양식시스템을 개발하였고[2], 이스라엘에서는 반잠수식 가두리 양식시스템을 개발하였다[3].(중략)

Off the southwest coast of Korea, changes in hydrographic fields from stratified state of summer to a vertically homogeneous one of winter appeared to occur most actively in November. During this transitional period coincident thermal and salinity fronts are formed along the boundary between the two water masses of cold coastal water with low salinity and of the Tsushima Current Water. Generally frontal zone lies where the bottom depth is about 70-90m except for the central region of the Cheju Strait in which the influence of the Tsushima Current is weak. Result of the drift bottle experiment in November 1930 supports the existence of the westward coastal current.

우리나라 연안 해역의 공동어장과 패류양식장에 서식하는 굴, 가리비, 반지락등 유용 조개류를 무차별 포식하는 불가사리는 패류양식 어민에게는 해적생물이라 불리우져, 이들을 퇴치하기 위한 대대적이고 적극적인 포획작업이 이루어지고 있다. 제주도의 경우도 마을 어장의 주요수산물인 전복, 소라, 오분자기등의 자원보존을 위한 불가사리 제거작업을 실시함과 동시에, 자원조성을 위한 종패 살포를 지속적으로 실시하고 있다. (중략)

Long-term wave distribution at Jeju sea is investigated by a numerical simulation based on the thirdgeneration wave model SWAN (Simulating WAves Nearshore). The Jeju sea which retains relatively high wave energy density among Korean coastal regions is considered to be a suitable site for wave power generation and the efficiency of wave power generation is closely related to local wave characteristics. The monthly mean of a large-scale long-term wave data from 1979 to 2002, which is provided by Korea Ocean Research & Development Institute. is used as the boundary condition of SWAN model simulation with 1km grid. An analysis of wave distribution concentrates on the seasonal variation and spatial distribution of significant wave heights, mean wave directions and mean wave periods. Significant wave heights are higher in winter and summer and the west sea of Jeju appears relatively higher than east's. The highest significant wave height occurs at the northeast sea in winter and the second highest significant wave height appears at the southeast sea in summer, while the significant wave heights in spring and autumn are relatively low but homogeneous. The distribution of wave directions reveals that except the rear region influenced by wave refraction, the northwest wave direction is dominant in summer and the southeast in winter. Wave periods are longer in summer and winter and the west sea of Jeju appears relatively longer than east's. The longest wave period occurs at the west sea in winter, and in summer it appears relatively homogeneous with a little longer period at the south sea.

Five specimens of Lethotremus awae (Cyclopteridae) were collected from the northern coastal waters of Jeju Island, Korea, during a survey on larval and juvenile fishes flocking to aquatic lamp in 2004 ~ 2007. They were characterized by having a spherical body with three barbel-like tubes on head and the first dorsal fin overgrown by skin with undiscernible rays as well as VIII-9 dorsal fin rays, 8 ~ 9 anal fin rays and 22 ~ 23 pectoral fin rays. A new Korean name, "Eom-ji-do-chi", was proposed for the species.

Based on a single specimen (207.0 mm SL) collected from the southern coastal waters of Jejudo Island, morphological characteristics of Antennarius commerson were described as the first reliable record from Korea. The species is characterized by having a globose body covered with small bifurcated spinules, three dorsal spines including a naked illicium and attached pectoral lobe, 13 dorsal fin soft rays, 8 anal fin rays, and 11 pectoral fin rays. We adopted a tentative Korean name previously suggested, "Keun-ssin-being-i", for the species.

In the southern sea of Korea and the areas of Tsushima warm currents the relationship between the distributions of eggs and larvae of anchovy (Engraulis japonica) and oceanic conditions was examined on July and August 1997, The south Korean coastal waters, the water temperature of below $20\~23^{\circ}$ and the salinity of above 33.0 (PSU), the mixed waters between the south Korean coastal waters and the Tsushima warm currents, $21\~25^{\circ}$ and $32.0\~32.5$ and the Tsushima warm currents, above $26^{\circ}$ and below 31.5 were distributed at the surface layer. The Tsushima warm currents were distributed at the northeast of Jeju Is. and off the southern sea of Korea. As an appearance of warm streamer, the mixed waters were intruded into the coastal areas of Komun Is.$\~$Sori Is. and Sori Is.$\~$Yokji Is.. Approximate paths of surface water by the drift card experiments were similar with the intrusions of the warm water identified from the water temperature and salinity distributions. The distributions of chlorophyll concentration were consistent with the distributions of water temperature and salinity, Anchovy eggs and larvae were mostly distributed at Komun Is., Yokji Is, and the southwest of Koie Is. where chlorophyll concentrations were high and cyclonic circulations by the warm water intrusions (warm streamers) were formed.

To investigate the variations of physico-chemical factors and microbial population, in ten stations at water region of coastal area of Chagwi-Do, Nutritive salts, water temperature, transparency, suspended solid, salinity, COD, DO, pH, heterotrophic bacteria, were analysed three times in September, November in 2004 and February in 2005. Heterotrophic bacteria in surface water was $3.5\times10^1\sim1.16\times10^3\;cfu\;mL^{-1}$, $0.4\times10^1\sim5.6\times10^1\;cfu\;mL^{-1}$, $0.4\times10^1\sim7.8\times10^1$ and bottom water counted $4.5\times10^1\sim1.0\times10^3\;cfu\;mL^{-1}$, $1.2\times10^1\sim1.5\times10^2\;cfu\;mL^{-1}$, $0.4\times10^1\sim4.4\times10^1\;cfu\;mL^{-1}$ in September, November 2004 and February 2005, respectively. The dominant species isolated from the coastal area of Chagwi-Do were identified to be Vibrio spp., Pseudoalteromonas spp. Psuedomonas spp, Bacillus spp., Alteromonas spp., Aeromonas spp., Psychrobacter spp., and Flavobacterium spp.
