Fourteen species of the family Penaeidae have been previously reported from the Korean waters (Kim, 1977: Cha et al., 2001). Recent collections from the coastal waters of Korea revealed the presence of two penaeid species, Metapenaeopsis lata Kubo, 1949 and Parapenaeopsis cultrirostris Alcock, 1906. These two species have been reported from Japan, East China Sea and Sou China Sea, and the Indo-West Pacific low South China Sea. We present brief notes of these species as two new members of the Korean fauna. (omitted)

For the first time the concentrations of copper, zinc, lead, cadmium and crome in the tissues from 17 specimens of cetaceans of Korean coast were determined. The measured concentrations of trace elements were considerably lower than the concentrations previously reported in cetaceans. In inter-species, Cd levels were higher in the kidney of Stejneger's beaked whales and the stomach, liver and lung of Risso's dolphin than in the tissues of minke whale and humpback whale.

We examined the characteristics of egg and larval distributions and catch changes of anchovy in relation to abnormally high sea temperature in the South Sea of Korea in summer 2015 and 2016. The densities of anchovy eggs and larvae in the southern coastal region were lower in July-August 2016 than in July-August 2015. In particular, anchovy eggs and larvae (approximately 5 mm TL) were rarely observed in the coastal region in August 2016 due to the abnormally high SST (up to $28^{\circ}C$), which was above the optimum spawning temperature of anchovy. The catch of non-swimming stage (< 2 cm TL) larval anchovy was lower in July-August 2016 than in July-August 2015. The decreased catch of larval anchovy in July-August 2016 could be attributed to decreased spawning density in June-July 2016. In contrast, the catch of swimming stage (> 2 cm TL) anchovy was increased in July-August 2016. In the summer of 2016, prominent sea temperature near the southern coast of Korea and sea temperature higher than $30^{\circ}C$ in the offshore region of the South Sea of Korea could greatly enhance the retention of swimming anchovies in the coastal fishing grounds.

The purposes of this study are to analyze problems in industrial classification of fisheries in Korea and to suggest future directions. Based on a thorough review of relevant literature, the study proposes a five-level scheme for classifying fisheries. The highest level should be the fisheries industry, and the next highest level ought to be fisheries. The medium level should include fishing, aquaculture, and fishery service industries. At the fourth level, fishing is to be further divided into sea fishery and inland fishery, aquaculture into sea-surface aquaculture and inland aquaculture, and fishery service industries into integrated fishery service and fishery distribution service. The lowest level is the most detailed. At this level, sea fishery is split into deep sea fishery, offshore fishery, and coastal fishery; sea-surface aquaculture consists of sea aquaculture, seed production aquaculture, and food organism aquaculture; integrated fishery service is further classified into fishery-related service and fishery information service.

Korea has experienced a Cochlodinium polykrikoides red tide 10 out of the last 10 years (1993-2002). This species of red tide has been experienced at least once by all the southern coast of the Korean peninsular and has been transported up the southeastern coast all the way to the northeastern coast since 1995. The impression is that red tide is spending and becoming more common not only in the nearest coastal water, but also in the offshore. (omitted)

1985년 한국 동해에서 격월로 수직채집된 어류 난$\cdot$자어와 동물부유생물, 그리고 동시에 관측된 수온과 염분자료를 이용하여 멸치난$\cdot$자어분포와 그 분포에 영향을 미치는 환경요인과의 관계를 연구하였다. 멸치난과 자어는 6월과 8월에 채집되었는데, 6월에는 고수온과 고염분역인 난수역에 분포하였다. 8월에는 난과 자어분포역이 외해역으로 이동하였다. 멸치난과 자어분포 및 수온, 염분, 동물부유생물 밀도의 관계를 분석한 결과 6월의 멸치 난과 자어의 분포밀도는 수온 및 염분의 분포와 정상관 관계에 있다고 분석되었다.

We examined the community structure of fish off the coast of Jindo Island in response to a cold water appearance in the southwestern sea of Korea each August between 2013–2015. Using a gape net with wings, we collected 31 taxa during the study period, wherein the most dominant species was Engraulis japonicus. Collichthys lucidus and Neosalanx andersoni, which are mainly distributed in the western sea of Korea, increased in abundance and were dominant in August 2013, possibly due to the apparent intrusion of cold water (< 19°C) from offshore into the coastal waters of Jindo Island. Meanwhile, Scomberomorus niphonius and Sardinella zunasi, which are known as warmwater migratory species, increased in abundance and were dominant in August 2015, likely influenced by the warmer water (> 20°C) at the coast, which resulted in a noticeable lessening of the cold water in the study area. However, no significant differences were observed in fish community structure in the month of August between 2013–1015. This implies that the small-scale spatial and temporal variations in the cold water had limited effects on the fish community structure, even though the abundances of several dominant species varied in the coastal waters.

한국 남해안에서 2003년~2004년의 4월, 6월, 8월에 멸치 알의 분포 및 해양환경 특성을 비교하고 냉수대 형성과의 관계를 분석하였다. 조사해역의 수온은 $10.2{\sim}30.7^{\circ}C$, 염분은 25.7~34.7, 클로로필은 $0.14{\sim}0.67{\mu}g/L$, 동물플랑크톤은 $111.52{\sim}262.37mg/m^3$의 범위였다. 멸치 알은 수온 $14.7{\sim}26.9^{\circ}C$와 염분 31.0~34.6 범위에서 주로 나타났고, 봄에서 여름으로 진행될수록 고수온과 저염분역에서 출현하였으며, 동물부유생물 생산의 증가와 함께 알의 평균분포밀도도 높아졌다. 2004년 8월의 멸치산란장은 외양의 난류수와 연안 냉수대간의 수온전선 외해측 해역에 집중되는 경향을 보이므로 연안역의 냉수대형성이 멸치 산란장분포의 제한요인이 되는 것으로 분석되었다.

In order to investigate the seasonal variation of watermass and fishery creatures in the adjacent sea of Naro Island, an oceanographic observation was carried out seasonally on the fishing grounds, and the sales performance data of the fisheries cooperative's joint market of Naro Island was examined by using a principal component analysis. The temperature and salinity ranged from 8.1 $^{\circ}C$ to 13.7 $^{\circ}C$ and from 33.1 psu to 34.3 psu in spring, from 14.5 $^{\circ}C$ to 24.2 $^{\circ}C$ and from 30.5 psu to 34.1 psu in summer, from 14.8 $^{\circ}C$ to 18.6 $^{\circ}C$ and from 30.1 psu to 34.0 psu in autumn, and from 4.3 $^{\circ}C$ to 10.1 $^{\circ}C$ and from 33.1 psu to 34.9 psu in winter, respectively. In winter and spring, the offshore water spread out to all sea areas of all water layers. In summer, the mixed waters covered the entire sea surface whereas the mixed water and offshore water covered the bottom. In autumn, the coastal water and mixed water appeared on the surface, but the mixed water was distributed widely on the bottom and the offshore water began to appear in the open sea. For two years from 2002 to 2003, 58 fishery creature species in total were sold in the fisheries cooperative's joint market of Naro Island. In general, the total of 50% fish were sold, and crustacea and mollusc by each 25%. Medium shrimp, whiparm octopus, blue crab, and octopus predominated. A number of species and biomass of fishery creatures were sold mostly in April and May, while they were sold the least in January and February. The seasonal sales results showed that mullet, angler, short necked clam, large shrimp, and webfoot octopus were sold mainly in spring, tonguefish, flathead, pomfret, glass eel, blue crab, whiparm octopus, and squid were sold mainly in summer, and octopus, medium shrimp, and spanish mackerel were sold mainly in autumn.

The effect of the oceanic condition on variations of the catches of Alaska pollack (Theragra chalcogramma) in the East Sea (the Japan Sea) is examined using monthly catches data of this fish and temperature data during 1972 to 1991. Since 1973 the catches of Alaska pollack have gradually increased, showing a peak in 1981, and then rapidly decreased after 1986. A significant negative correlation was found between variations of the catches and the temperature at 50 m depth offshore Mukho. In 1981, the year of the highest catches in the study period, the water mass in the Eastern Korean Coastal Sea of the East Sea was extremely cold, while the year of poor catch, 1979, was much warmer than the annual mean temperature. The results show that the temperature variations around the Eastern Korean Coastal Sea play an important role in the variations of the catches of Alaska pollack, implying that the effect of the Tsushima Warm Current is also very important.
