The fish community of small freshwater ecosystems gets easily disturbed by direct or indirect human induced disturbances during the period of urbanization. Urbanization is one of factors that generate changes in stream and influences fish fauna in developed countries. This study was conducted in Busan Metropolitan City from 2001 to 2004. In order to investigate the fish community, the city was divided into 3 parts, eastern, central and western. A total of 3,206 individuals of 46 species from 19 families were collected from 55 sites. The dominant species was Rhynchocypris oxycephalus, whereas Zacco temminckii was the subdominant species. Cluster analysis was conducted using primary freshwater fish species collected from each stream. As a result of the analysis, study sites were well differentiated into 3 parts. Two species of Z. temminckii and R. oxycephalus represented the upper part of the stream and Carassius cuvieri, Acheilognathus rhombeus, Hemiculter eigenmanni and Micropterus salmoides represented the middle and lower parts of the stream. When compared with previous studies, fish community of the eastern part of the Busan city where urbanization is in progress, showed similar patterns to the central part. At the time of the habitat restoration of fish fauna in stream, appropriate selection of fish species should be made through analysis of stream character and biogeographic distribution of fish, and long-term monitoring is also needed for sustaining the management of fish fauna.

The fish fauna and community structure were surveyed at the Naerin Stream of Puk'an River from June 1996 to September 1997. The fishes collected were 36 species, 28 genera belonging to 10 families, in which 16 species were endemic species of Korea. Oncorhynchus mykiss was an exotic fish. The dominant species was Zacco temmincki(relative abundance 42.94%), and subdominant species was Moroco kumgangensis(12.91%). The rare species less than 0.03% of all were Opsariichthys bidens, Squalidus japonicus coreanus, Misgurnus mizolepis, Leiocassis ussuriensis and Siniperca scherzeri. The species diversity, evenness, and dominance index on the fish community were 0.947, 0.609, and 0.218.

During the investigation of fish fauna from the Kokunsan Islands off west coast of Korea from 1989 to 1993, authors confirmed 102 fish species belonging to 81 genera, 50 families and 12 orders. Of these the following 8 species were common : Herengila zunasi, Engraulis japonica, Johnius grypotus, Pholis fangi, Repomucenus ornatipinnis, Chasmichthys gulosus, Tridentiger trigonocephalus, and Cynoglossus joyneri. Of the twelve orders recognized herein, Perciformes, Scorpaeniformes and Pleuronectiformes include approximately 74% of the fish fauna in this area. The largest family is the Gobiidae representing 12 species. Pholis fangi, Repomucenus ornatipinnis, Repomucenus koreanus, Takifugu flavidus and Takifugu obscurus collected are endemic to the Yellow Sea. Fifteen specimens of an unknown Sebastes species was collected. This species resembles Sebastes hubbsi and Sebastes longispinnis, but the species differs from other sebastes species reported in Korea in the number of dorsal fin rays, lateral line pores, gill rakers and in color patterns of body sides.

(1) The author surveyed the environmental factors and the fauna of Sung-Yoo Cave(360m in length) from November 29 to December 2, 1961. (2) Air temperature, water temperature, moisture, water depth, water gravity, oxygen concentration carbon dioxide concentration and pH in water of the cave were studied as enveronmental factors. The results are shown in the Table 1~7 and Fig.3. (3) Four species of troglobite (22.2%). seven of troglophile(38.9%). four of troglozene(22.2%). and three of parasite constitute the terrestrial fauna of Sung-yoo Cave. In the other hand, all of the aquatic fauna(4 species of fish) of the cave were troglozene. (5) None of the species of animals listed in this paper has ever been recorded in Korea.

This study was to analyze fish composition and ecological indicator characteristics from eight sampling sites of Geum River, October 2007. Total number of family and species sampled were 9 and 40. The most dominant family was Cyprinidae (27 species, 85%), and then followed by Cobitidae, Odomtobutidae, and Gobiidae. Constancy values of Zacco platypus and Zacco temminckii were 1.00 and 0.30, respectively, and the relative abundance of Acheilognathus koreensis and Pseudogobio esocinus were greater than 5% of the total. The number of Korean endemic species sampled in this Geum River study was 7 family 19 species, which is 47.5% of total 40 species, and endangered species of Pseudopungtungia nigra and Gobiobotia brevibarba were only 0.5% of the total and these species were only distributed within the upstream regions. Exotic species, Micropterus salmoides, which is known as large-mouth bass, were observed in two sites of G3 and G7. Analytical results of fish community showed that community dominance index was 0.19, which is low, and the species evenness index (0.74), diversity index (2.03), and richness index (3.00) appeared high. These results indicate that structure of fish community is stable in the Geum River. According to various guilds analysis, the relative abundance of tolerant and omnivores at all sites were 40% and 47% of the total, respectively. This monitoring data may contribute changes of fish fauna and compositions in relation to habitat modifications and chemical water quality degradations in the future.

The goal of this study was to provide basic data necessary for managing fish in the Seomgang River by confirming diversity of fish species in the Seomgang River and determining the degree of change in fish species through a comparison with earlier related work. Growth rate, obesity level, and temporal and spatial reproductive capacities were analyzed to determine growth characteristics of dominant species. Fish fauna and structure of the fish community were surveyed at three different time points from October of 2020 to August of 2021 at eight sites. In addition, growth characteristics of Zacco platypus from June of 2021 to July of 2022 at four sites were determined. A total of 3,999 individuals, 43 species, and ten families of fish were identified. Among these species, 19 (44.19%) were Korean endemic species and four (9.30%) were endangered species. The dominant species was Z. platypus. Pungtungia herzi was identified as a subdominant species. An analysis of length-weight relationships and condition factor (k) of Z. platypus confirmed a good state of growth. As a result of a frequency analysis of the total length, the life cycle of the Z. platypus population living in the Seomgang River was found to be stable. According to gonadosomatic index (GSI) analysis, the spawning season of Z. platypus was estimated to occur after May, consistent with the literature.

The freshwater fish fauna of Chirisan National Park, where dramatic environment changes will be expected due to develop tour and hiking, was censused to establish base line data for natural conservation program Four species belonging to 3 families included in Cyprindae, Amblycitidas and the present fishes were collected in this region. Dominant species was dark chub, therefore chareful organization of the tour development and the preservation of ichthyological fauna are strongly recommended.

The fish fauna was investigated on summer (from July 28 to Aug. 2) and winter (December, 1994) at the Munsom in Cheju-do. As a result of this study, the fishes identified in these areas were classified into 79 species involved in 35 families. And seven species unrecorded in Korea were found, i.e. Halicampus boothae, Cirrhitichthys aprinus, Stegastus altus, Parupeneus sp., Pomacentrus sp., Pomacentrus sp., and Pomacentridae sp. In this region large number species of family Pomacentridae (12 species), family Labridae (9 species), Scorpaeinidae(6 species) and Blennidae (5 species) were observed in summer.
