  • The species composition of larval fish assemblages in the Nakdong River estuary, Korea, was determined using monthly samples collected between September 2010 and August 2011 at two stations. A total of forty three larval species were collected during the study. Among forty three taxa of fish larvae, summer gobies, Clupea pallasii, Engraulis japonicus, spring gobies, Konosirus punctatus, winter gobies, Sardinops melanostictus, Coilia nasus were dominant taxa, and these eight taxa accounted for 95.0% in the total number of individuals. Species composition and abundance varied greatly spatio-temprally showing the peak abundances of fish larvae in August 2011, and a few fish larvae were occurred in November 2010. Cluster analysis based on the number of individuals of fish larvae showed that 21 month-station sampling units were classified into five groups at the similarity level of 50%, and the results of ANOSIM and SIMPER analysis revealed significant differences in community structure among five groups.

  • The osteological characteristics of Mudhopper, P. cantonensis, was described and compared with its related species, Tridentiger obscurus, Synechogobius hasta and Odontogobius platycephala The skeletal structures of P. canionensis were distinctly different from those of other species in many respects: the form of the neurocranium, the pterygoid, the radial and the parhypural, the fused state between ribs and hypomerals. However, in respect of having five branchiostegals, two epurals and hypomerals, P. cantonensis were in common with T obscurus, S. hasia and O. platycephala.

  • Twenty five specimens (40.8~58.4 mm SL) of Gymnogobius taranetzi (Family Gobiidae) were collected from the estuary of Samcheok-si and Yangyang-gun, Gangwon-do, Korea. This species is distinguished from other Gymnogobius species by oculoscapular canals not extending anteriorly through interorbital space, but replaced by rows of sensory papillae; oculoscapular canal pore C is absent; some yellow bands on body in female with breeding color. The new Korean name "Dong-hae-nal-mang-duk" is proposed for this species.

  • 망둑어과 어류는 매우 유사한 형태를 지니고 있으며, 매우 넓게 서식지가 중복되고 있어 근연종간 자원 이용 따른 경쟁 은 매우 클것이다. 망둑어과 어류의 근연종간 자원의 분할 이용에 대한 연구는 간단한 먹이 생물의 분석 등에 대해서만 알려져 있을 뿐 서식지의 분할 이용과 서로 다른 섭이전략에 따른 공존에 대한 연구는 없었다. (중략)

  • 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".

  • Fifteen gobids specimens first collected from the southern coastal waters of Tongyeong, Gyeongsangnam-do, were identified as the Suruga fundicola from Korea. The species, representing a new Korean record, is characterized by having VII-I, 16~17 dorsal fin rays, I, 15~16 anal fin rays, 37~42 lateral line scales, notably large eye and narrow interorbital space, scaleless cheek and opercle, no babel, teeth rather strong, and 6~7 dusky spots on sides. A new Korean name, "Keun-nun-mangduk-sok" and "Keun-nun-mang-duk" is proposed for the genus and species, respectively.

  • The Eyebar goby, Gnatholepis cauerensis is reported firstly from Korea, based on four specimens (36.3~47.1 mm in SL) collected at depth range of 12~16 m in the southern coastal waters of Jejudo Island, Korea. They are characterized by having mostly ctenoid scales on body, head including cheek, opercle, and middle of predorsal region with cycloid scales, and a unique coloration of yellow blotch with marginally black marking above pectoral fin base as well as transverse black bar below eye. A new Korean name, "Geom-eun-nun-ddi-mang-dug", is proposed for the species.
