Recently, the KFDA(Korea Food & Drug Administration) has announced that the Malachite Green was found from imported fishes and eels. Malachite Green is used for remedy of diseased fishes. The administration has a plan to intensify monitoring system for distribution of fishes. It is necessary to operate the improved warning system for public health.

아산만 해역의 동물플랑크톤 분포

명철수,유재명 한국해양학회 1994 韓國海洋學會誌 Vol.29 No.4

Distribution of zooplankton was investigated at 30 stations in Asan Bay, an embayment in the western coast of Korea, seasonally in August and October of 1991, and January and April of 1992. Abundances of zooplankton ranged from 240 to 1,458 indiv./m$^3$. Copepods were the predominant constituent, which comprised 88% of total zooplankton abundance. Acartia bifilosa dominated from fall to spring, A. pacifica in summer and Paracalanus parvus in fall. Abundances of zooplankton were related with phytoplankton standing crops and larval fish. In spring, when phytoplankton standing crops were high, zooplankton abundances were highly correlated with phytoplankton standing crops (r$^2$=0.66, p<0.01, n=30). Results of cluster analysis based on the abundance data of zooplankton showed that the study area was divided into two areas, i.e., outer-bay and inner-bay.

The purpose of this study was to investigate the temporal and spatial variability of taxonomic groups and major species of the mesozooplankton community in Lake Shihwa, Korea. Monthly collections were carried out at five stations in Lake Shihwa for a period of one year. The mesozooplankton community showed distinct seasonal variability with water temperature and salinity. Major mesozooplankton species in each seasonal community were derived from non-metric MDS and SIMPER as follows: winter community (Acartia hongi and Eurytemora pacifica), spring community (Acartia hudsonica and Polychaeta larvae),summer community (Acartia sinjiensis, Pavocalanus crassirostris, Evadne tergestina and Cirripedia nauplii) and fall community (Paracalanus indicus and Podon leuckarti). The succession of the seasonal species, A. hudsonica and A. sinjiensis, was the most remarkable event during the seasonal changes of the mesozooplankton community. The species response curve of these species fitted with the logistic regression in relation to water temperature and salinity. The curve also correctly represented the characteristics of the occurrence of A. hudsonica and A. sinjiensis in Lake Shihwa.

한국 남해에 출현하는 요각류에 관한 고찰

유재명,김웅서,명철수 한국수산학회 1993 한국수산과학회지 Vol.26 No.3

한국 남해에서 출현하는 요각류에 대한 현재까지 발표된 분류학과 생태학 논문들을 대상으로, 요각류의 종조성, 개체수, 분포, 계절변화 등을 검토하였다. 그 결과 총 179종의 요각류가 동정되었으며, 연안역과 내만역의 우점종들은 Acartia clausi, Paracalanus parvus, Oithona similis, Oithona nana 등이었고, 이는 제주도 부근의 외양에서 발표된 우점종들과는 상이하였다. 또한 이 논문에서는 남해에 출현하는 지표종들에 관해서도 토의를 하였다. 요각류의 개체수는 일반적으로 외양역보다는 연안역에서 최대 평균 390,000개체/㎥ 이상으로 높게 나타났다. 한편 요각류의 계절별 개체수 변화에는, 주로 춘계와 추계에 각각 개체수 극대치가 나타나는 유형과, 하계에서 추계에 걸쳐 극대치가 나타나는 두가지 유형이 있는 것으로 나타났다. Ecological and taxonomical studies on the copepods were reviewed in order to make data bases on the species composition, abundance, distributional pattern, and seasonal variations of copepods in the South Sea of Korea. Total 179 species have been reported in this area. The dominant species in the coastal waters and embayments, such as Acartia clausi, Paracalanus parvus, Oithona similis, and Oithona nana, were different from those reported in the offshore waters around Cheju Island. Indicator species of the South Sea were also discussed in this paper. Copepod abundances were higher in the coastal waters, up to more than 390,000 individuals/㎥(collected with a 150㎛ mesh net), than in the offshore waters. There were two types of temporal variations in copepod abundances in the coastal waters, i.e., bimodal abundance peaks in spring and fall, and unimodal peak during summer to early fall.

Various marine plankton were observed in the ballast water of vessels entering Incheon and Busan harbors. The ballast water of which age ranged from 2 to 54 days originated from the coastal waters of New Zealand, Taiwan, Singapore, Japan, Hong Kong and Pakistan, and from the Pacific Ocean. The total number of marine plankton taxa in 9 ballast tanks of different ships was 170: 90 phytoplankton, 24 protozoa and 56 zooplankton. The most diverse taxonomic groups were diatoms in phytoplankton, ciliates in protozoa and copepods in zooplankton. Classifying the specimens by size, above 50% of the number species of phytoplankton belonged to the size range between 50 and 150mm. Protozoa and metazooplankton were found frequently in the size range between 50 and 120mm, and 500 and 1,000mm, respectively. The relationship between the species number and the age of ballast water was not significant. This is because of difference of filtration amounts derived from discordance of collecting samples. Among plankton observed in ballast water, some harmful algae and non-indigenous aquatic species were identified. Therefore, we need to investigate whether these species can inhabit in Korean coastal waters in further study.

원자력 발전소의 온배수 배출량 변화에 따른 대형저서동물 군집의 공간 변화

This study analyzed the species composition and density of a macrobenthic community according to variations in the thermal discharge volumes of a nuclear power plant before, during, and after the shutdown of the nuclear power plant during two periods. In this study, 369 macrobenthic fauna species were collected, and their mean density was 1,712 ind. m−2. The number of species and diversity of macrobenthic fauna decreased with distance from the thermal discharge area, regardless of whether the nuclear plant shutdown or not. Many macrobenthic taxa appeared near the thermal discharge area, but polychaetes species were more prominent in outer areas than at the discharge area. The density of macrobenthic fauna decreased with distance from the thermal discharge area during a plant shutdown in the fall of 2011, but increased, except at two sites, near the discharge area in the winter of 2012. Cluster analysis indicated that the spatial distribution of the macrobenthic community changed in areas near the nuclear power plant after a shutdown period; that is, the station group I, in areas near the nuclear power plant, became narrower after the shutdown, but it recovered to previously occupied areas after the nuclear power plant began operating again. Opportunistic species, such as the polychaetes Lumbrineris longifolia (= Scoletoma longifolia) and Mediomastus californiensis, which were present in high densities near thermal discharge areas, decreased after the shutdown but recovered after the plant re-opened. The number of species and diversity of the macrofauna and the density of dominant species showed a significant correlation with temperature, except in winter periods. The results of this study revealed that changes in the amount of thermal discharge before and after the shutdown of a nuclear power plant could exert an influence on the structure of macrobenthic community within the thermal discharge areas depending on the season.

In order to examine the transition of zooplankton community by the Saemangeum sea dyke, the temporal and spatial distribution of zooplankton community with relation to environmental variables was investigated using data collected in 2004 and 2005. Sixty-one zooplankton taxa were identified. Average abundance (except Noctiluca scintillans) ranged from 236 to 1810 indiv. m-3, and was the highest in May 2005 and the lowest in February 2005. Dominant species were Acartia hongi and Paracalanus indicus, and cirripedia nauplii and zoea were dominant groups. After the closure of the 4th sea dyke, brackish species such as Tortanus derjugini and Pseudodiaptomus inopinus are widely distributed while the abundance of N. scintillans decreased in the northern area inside the dyke. In canonical correspondence analysis (CCA) for examining the relationships among zooplankton, stations and environmental variables, the northern area inside the dyke was distinguished from the other areas and was represented by Acartia spp. and brackish copepods. Also, this area was characterized by high chlorophyll aconcentration and COD, and low diversity.
