The purpose of this study was, as a preliminary step for understanding the whole aspects of the impacts of a weir on the ecosystems in upper and lower streams, to find out the impacts of the weirs with and without a fish-way. A survey on the aquatic ecosystem of upper and lower streams of weirs in Ham-an Stream was carried out from June to October, 2006. Results of the investigation showed that some meaningful effects on the ecosystems had occurred by the weirs. The fish fauna in upper stream of the weir with a fish-way appeared to include 3 families, 8 species, and 184 individuals, while that in the lower stream of the weir appeared to include 5 families, 14 species, and 664 individuals. The fish fauna in the upper stream of the weir without a fish-way appeared to include 3 families, 9 species, 107 individuals, while that in the lower stream of the weir appeared to include 9 families, 19 species, 520 individuals, disclosing that, no matter with or without a fish-way, fish fauna species diversity and size of population were more abundant and bigger in the lower stream than in the upper stream, but that difference of fish fauna species diversities between upper and lower streams of the weirs appeared to be bigger for the weir with a fish-way than for the weir without a fish-way. Benthos species diversity and size of population were found to be more abundant and bigger in lower stream than in upper stream, and in wet season than in dry season.

This study was carried out to survey the fauna of some parks around Kunsan-city and to establish biological impact on the development of those parks. Among the fauna surveyed, insects consist of 74 species in 49 families and 13 orders. The insect fauna was poor, because the environment was made of simple flora and mostly farmland. Fish in the reservoir of Wolmyong-Park consist of 7 species. Among them, Ctenopharyngodon idellus is an exotic species and characterized with its voracious plantfeeding. This fish severely destroyed the habitats and spawning sites of other sympatric fish. For the conservation of non-exotic fish, birds, and mammals in the area, the integrated biological direction would be needed.

Fish fauna in the eastern Yellow Sea was determined using samples collected by an otter trawl from September 1999 to November 2001. The fish consisted of 97 species belonging to 80 genera and 50 families. The major taxa were the Perciformes (40 spp.), Pleuronectiformes (17 spp.), Scorpaeniformes (11 spp.) and Clupeiformes (10 spp.). Larimichthys polyactis, Engraulis japonicus, Liparis tanakai, Pampus echinogaster, Lophius lituron and Collichthys niveatus were predominated in abundance in the study area. The composition of the fish fauna has changed during the last three decades.

Fish fauna and community structure were investigated at 2003, 2004 and 2006 in Lake Paldang and its inflows. In this survey, we collected 54 species belong to 14 families. Family Cyprinidae take 51.9% (28 species), Cobitidae and Gobiidae occupied 7.4% (each 4 species), respectively. E. erythropterus (11.8%) was dominant species and L. macrochirus (10.2%), designated as an ecosystem-invasive alien fish species by Ministry of Environment, M. yaluensis (9.1%), Z. platypus (7.7%) and R. brunneus (6.7%) were dominated in turn. H. molitrix, C. lutheri, P. altivelis, S. microdorsalis, L. costata. S. gracilis majimae, A. rivularis, P. koreanus. S. scherzeri and O. platycephala were rare species (less than 0.1% in relative abundance). In-lake area, 36 species of fishes belonging to 11 families were collected, and 48 species of 13 families were from inflows. The number of Korean endemic species were 19 species (35.2%), and 4 kinds of exotic species (7.4%), that is, C. cuvieri, H. molitrix, L. macrochirus and M. salmoides were found at this survey area. It was revealed by the analysis of fish community that diversity and richness indices were prominent at tributaries, and dominance index was high at the main body of Lake Paldang. Fish fauna showed rapid decline after dam construction which make the mid-Han river systems to lentic ecosystem, so many of meander-riffle fishes were disappeared dramatically. But after 1990s when installation of small scale wastewater treatment plants started in watershed, the water quality of small tributaries was improved. And also, expansion of the natural macrophytic vegetation of littoral zone should contribute to the development of diverse fish fauna in Lake Paldang.

This study is performed to clarify the fish fauna and fish habitat of downstream of Singok submerged weir within Han River estuary during April ~ December 2009. It was studied at the nine sites of Han River estuary area. The three of them were located in the mainstream of Han River and six of them were located in three wetlands which as Sannam, Janghang and Dolbangguji. Total fish fauna was identified as 9 order 15 family and 38 species (2,230 individuals). It was divided as 8 order 11 family 28 species from three sites in the mainstream of Han River and as 5 order 8 family 19 species in waterways at mud flats of three wetlands. It was made up the fish fauna as 3 order 4 family 12 species during the survey period at the waterways in the rice paddies. Hemibarbus labeo was dominant species in the whole research sites and waterways at mud flats. Carassius auratus was dominant species in the waterways between rice paddies and Chelon haematocheilus was dominant species in mainstream of Han River estuary.

Benthic environments and composition of macrobenthic fauna around the marine fish culture cages were studied to clarify the effect of fish farming near Tongyong from August, 1995 to february, 1996. Sediment grain size and bottom dissolved oxygen under the fish cages were similar to that of a control site, but organic content was higher under the cages. Fewer species were found under the fish cages than under the control site, but conspicuously higher density was obtained under cages. Capitella capitals, Nebalia bipes were dominant infauna, and Asterina pertinifera and Astelias amurensis were dominant epifauna under the fish cage whereas Lumbrineris longifolia and Anphioplus sp. dominated in the control site. Diversity index showed seasonal variation under the fish cages, but showed little variation at the control site. The benthic fauna under the fish cages showed different community structures from the control site. As results, the fish culture cages affected the benthic environment and the community structure of benthic fauna by input of the organic content and biological effects such as dead shells.

The fish fauna was investigated around Dokdo in the East Sea from Oct. 15 to Oct. 16, 1997 and May 12 to 15, 1999 Fishes found in this area were 63 species in 28 families : 58 species of 25 families in autumn (Oct., 1997), and 30 species of 15 families in spring (May, 1999). Apogon cookii and Tripterigion bapturum were unrecorded species in Korea. The 11 species of subtropical fishes including Pomacentridae (4 species) and Apogonidae (3 species) occupied about 20% of the fish fauna in autumn, whereas these subtropical fishes did not occur in spring.

Eighteen species of fish were identified by SCUBA diving observations around experimental artificial reefs at Tongyeong marine ranching area between November 1998 and November 1999. The highest species number of 14 was observed in September while the lowest number of 2 was observed in November. Fishes showed three typical behavioral patterns against the experimental artificial reef.
