  • Urban streams are degrading functional role due to development and pollution. This study chose the representative stream of Do-rim and identified flora and fauna. The ecological survey aimed at identifying indicator of urban streams for measuring urban healthiness and we discussed the possibility of wetland conservation area. From the beginning of Dorim stream to An-yang mixture we were successfully identified 113 species of plants, 9 of mammals, 23 of birds, 4 of amphibians, 2 of reptiles and 2 of fish species. Terrestrial insects were 71 species. The wetland vegetation is quite various and we suggested 4 different vegetation zones (aquatic vegetation zone, emergent zone, riparian-meadow zone, riparian-woodland zone) depending on distance from the flowing water stream and vegetation characteristics for urban stream management.

  • A single specimen of Synodus fuscus belonging to the genus Synodus in family Synodontidae was firstly collected from the coastal waters of Jeju Island, Korea. We newly add this species to the Korean fish fauna and propose its new Korean name, "Mo-rae-kkot-dong-myeol". This species was characterized by having no conspicuous pigmented area on operculum. The dorsal fin base is shorter than 1/2 of the head length. The morphological measurements and counts of Synodus fuscus were described in detail and a key to species of the genus Synodus from Korea provided in this study.

  • A specimen of Aspasma minima (25.4 mm SL) belonging to the family Gobiesocidae was collected from coastal waters near Hamdeok in Jeju Island, Korea. This species is characterized by having 6~9 dorsal fin rays, 5~9 anal fin rays, 20~24 pectoral fin rays, many red spots on head and body when fresh, and posterior end of upper jaw not reaching anterior margin of eye. Our specimen is well matched in its morphological characteristics with previous descriptions of A. minima. Thus, we newly add this species to the Korean fish fauna and propose its new Korean name, "Kkoma-hak-chi".

  • Two specimens of Asterorhombus intermedius (130.0~143.4 mm SL), belonging to the family Bothidae, were firstly collected from the coastal waters of Jeju Island, Korea. This species was characterized by having 54~56 lateral line scales, first dorsal-fin ray with a long projection, and various size of black spots on the body. The morphological characteristics matched well with previous description of A. intermedius. Therefore, we add this species to the Korean fish fauna and propose its Korean name, "Git-teol-dung-geul-neob-chi-sok" and "Git-teol-dung-geul-neob-chi" for the genus and species, respectively.

  • A single bothid specimen (113.9 mm in standard length) was collected by bottom trawl from southern Jejudo Island, Korea. It was easily identified as Kamoharaia megastoma (Kamohara, 1936), based on extremely large mouth. The species is characterized by maxillary extending beyond eyes, three pairs of long curved canines on lower jaw, tip of vomer projecting into mouth cavity, blackish pectoral fin, and blind side without lateral line. We described it as the first record to Korean fish fauna, and proposed the new Korean name, "Keun-ip-dung-geul-neop-chi" for this species.

  • A single specimen of Caranx melampygus (113 mm standard length), belonging to the family Carangidae, was firstly collected by a set net from the coastal waters of Jejudo Island, Korea. This species is morphologically similar to C. sexfasciatus except for the posterior end of maxilla not reaching the posterior margin of eye (vs. reaching in C. sexfasciatus) and no black blotch on the upper part of opercle (vs. black blotch). We newly add this species to the Korean fish fauna and propose its new Korean name "Jag-eun-ip-jul-jeon-gaeng-i" for the species because it has relatively smaller upper jaw when compared with C. sexfasciatus.

  • Scolecenchelys borealis was first added to the Korean fish fauna based on one leptocephalus specimen (total length (TL) 59.2 mm) collected from Dokdo, in the East Sea. Recently, however, Scolecenchelys borealis has been treated as a junior synonym of Scolecenchelys aoki, necessitating review of the scientific name S. borealis. This study describes the morphological characteristics of S. aoki based on an adult specimen (TL 230.0 mm) collected from the sea south of Korea and compares its mitochondrial DNA 12S rRNA sequence with that of the S. borealis leptocephalus. The adult S. aoki is characterized by several morphological features: vertebral formula 59-55-135; preanal lateral pores 55; infraorbital pores two; teeth on upper jaw visible externally when the mouth is closed; the dorsal fin originates just behind the anus; both jaws and vomerine teeth are conical, arranged in two rows. An analysis of an 886-base paire sequence of the 12S rRNA showed that adult S. aoki was concordant with the S. borealis leptocephalus (sensu Ji et al., 2012), indicating that both are the same species.

  • A specimen of Redigobius bikolanus (29.0 mm SL) belonging to the family Gobiidae was collected by a hand net from the estuary of Changgo-cheon (river) in Andeok-myeon, Jeju Island, Korea. This specimen was characterized by having 26 lateral line scales, 7 predorsal scales, 7 transverse scales, anterior oculoscapular canal, preopercular canal, and four black spots between origin of anal fin and lower origin of caudal fin. The morphological characteristics of the specimen well matched those of Redigobius bikolanus previously reported. Thus, we newly add this species to the list of Korean fish fauna and propose its new Korean name, "Jeom-bak-i-mang-duk".

  • A single specimen belonging to the family Diodontidae was collected from Seo-gwi-po, Jeju Island, Korea in July 2013 and was identified as Diodon hystrix Linnaeus, 1758, a species new to the Korean fish fauna. The species is characterized by 14 dorsal fin rays, 14 anal fin rays, spines on the dorsal and ventral surfaces of the caudal peduncle, and many small black spots on all fins except the anal fin. The most similar species, Diodon holocanthus, is well distinguished from D. hystrix by the absence of black spots on the dorsal and caudal fins, and the lack of a spine on the dorsal surface of the caudal peduncle. Accordingly, we describe herein the morphological traits of D. hystrix and suggest its new Korean name, "Jan-jeom-bak-i-ga-si-bok".

  • An investigation of fish fauna was conducted based on the specimens from the Taean International Marine Park, off West Coast of Korea in 2005. They were collected by small seine net and stake net. The collected fishes were composed of 27 species belongs to 15 families and 8 orders. The dominant species were gobids of Favonigobius gymmnauchen in the sand area, Chamichthys gulosus and C. dolichognathus in the rocky area. The Korean endemic species were two species of Zoarchias uchidai and Repomucenus koreanus. But Porocottus leptosomus that described as a new species on the basis of specimens collected from this area in 2002 was not collected in this study.
