  • 1983년 7월부터 1995년 10월까지 국내에서 채집된 망둑어아목 어류 4과 28속 51종을 대상으로 몸의 부위에 따른 비늘의 종류와 미병부 측면 비늘의 형태를 조사 비교하였다. Luciogobius grandis, L. guttatus 및 Leucopsarion petersi를 제외한 48종은 비늘을 가지고 있었으며, 비늘은 즐린과 원린의 2종류로 구분되었다. 특징적인 것은 동일 개체 내에서도 어체의 각 부위에 따라 종류, 형태, 크기, 초점의 위치, 구와 융기선수 및 소극수 등이 다르게 나타나지만 속과 종 수준에서 비교적 안정된 특징을 보여주었으며, 비늘의 유무와 그 종류에 따라 망둑어아목 어류는 5개의 group으로 분류되었다. 미병부 비늘의 형태는 5각형, 6각형, 원형 및 타원형으로 구분되었다. 또한 Odontobutis obscura interrupta, O. platycephala 및 Hypseleotris swinhoni는 2∼3열의 소극을 가지고 있고, Eutaeniichtys gilli와 Parioglossus dotui는 비늘의 초점이 중앙에 위치하고 있어 다른 망둑어아목 어류와 차이를 나타내었다.

  • Thirty three species belonging to twenty genera in the subfamily Gobiinae of Korea were reviewed and key to species and genera were provided. Among them twenty seven species captured during 1985-1987 were examined on the cephalic sensory canal systems for the taxonomic review, and classified into 4 groups based on the presence or absence of the canal and their canal pore patterns. It was confirmed that the pore patterns of preopercular and anterior ocular-scapular canal were important in the diagnosis of gobiid genera or species and in the discussion of the specialized species group. It was considered that the genus of Acentrogobius masago should be transferred to Pseudogobius from Acentrogobius, because A. masago was more similar to P. jausnicus than to A. pflaumi and its congeneric species in their cephalicc sensory canal systems. Some populations of Chaenogobius annularis and Acanthogobius lactipes showed the geographical variations in cephalic pit organs and the number of predorsal scales. The endemic gobiid species was not found the Korean waters, but some species showed a disjunct distributions between the west and the east coast waters in Korea. The south coast was inhabited by the abundant species including twenty seven species of seventeen genera. The genera of Acanthogobius, Chaenogobius, and Chasmichthys were considered to be the common genera in Korean waters.

  • Mudskipper로 알려진 망둑어과 어류인 말뚝망둑어 Periophthalmus modestus는 구나 기수역의 갯벌바닥에 서식하면서 간조시에는 물 밖으로 나와 육상의 갯벌을 뛰어다니거나 또는 추운 계절에는 갯벌에 굴을 파서 생활하는 amphibious habit를 갖고 있다. 말뚝망둑어와 비슷한 서식환경을 가지는 드렁허리 Monoterus albus와 Amphinous는 용존산소를 이용한 수중호흡 이외에 피부를 이용한 공기호흡(cutaneous respiration)을 병행하는 dual respiration system을 갖는 것으로 알려져 있으며 (Liem, 1967; Mittal and Munshi, 1971) 또한 쉽게 건조가 되는 연못, 농수로 또는 진흙바탕에 서식하는 Misgurnus fossilis(Jakuboski, 1958), M. anguillicauda (Park and Kim, 1999)에서도 피부를 이용한 공기호흡이 알려져 있다. 그러나 이러한 어류들의 피부구조는 말뚝망둑어 피부와 많은 차이점을 보여 주고 있는 본 조사는 말뚝망둑어의 피부의 특징을 조사하고 및 이들의 호흡체계에 대한 기초자료를 얻고자 한다.

  • Several osteological characters of 45 species belonging to 26 genera and 4 subfamilies in th family Gobiidae were surveyed based on 348 specimens collected from April, 1984 to September, 1992 in the southern part of Korea. The characters include the following: first dorsal-fin pterygiophore formula, vertebral number, epural number, and number of anal-fin pterygiophores anterior to the first haemal spine. The first dorsal-fin pterygiophore formula and epural number showed considerable stability at the generic level, and the apeared useful characters at the species level. Among them, the epural number used formerly to distinguish gobiid subfamilies was considered to be unimpotant taxonomic character in the classification of the subfamily Gobiinae.

  • A gobiid fish, Parioglossus dotui Tomiyama is described from 359 specimens collected at Cheju-do and Pusan, in August 1994 of 1986. This is the first definitive record of the species in the Korean waters. Parioglossus dotui having a small-sized body usually is found swimming in schools. The branchiostegals are 5 in number on each side. It grows up to 40mm in total length. Most of ventral fins are separated and connected with rudimentray membrane. In this species, the lateral line were indistincet or absent. The caudal fin slightly emarginates or truncates in both sexes, with a dark spot at the border of the base. It Inhabits inlet waters and estuaries of rivers. "Deungsul mang-dug" is proposed as Korean name of this species.

  • 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.

  • The gobiidae, $Tridentiger$ $trigonocephalus$, $Chasmichtthys$ $dolichognathus$ and $Favonigobius$ $gymnauchen$ were reared for 4 weeks under 0~33.6‰ salinity conditions to examine the effects of various salinity on its survival and growth. Survival rate of $C.$ $dolichognathus$ and $F.$ $gymnauchen$ were significantly declined below 3.4‰ and 0‰, respectively. Growth rate of $T.$ $trigonocephalus$ was significantly reduced 0‰ salinity. Growth rate of $C.$ $dolichognathus$ and $F.$ $gymnauchen$ exposed to ${\geq}$13.4‰ and ${\geq}$6.7‰ were significantly higher than those of gobiidae exposed to below ${\leq}$10.1‰ and ${\leq}$3.4‰ salinity, respectively. This study reveled that low salinity (${\leq}$3.4‰) reduced survival and growth rates of the 3 gobiidae suggesting potential influence on the natural mortality of gobiidae in the coastal areas.

  • The territorial behavior of the naked goby, Gobiosoma bosci, was observed in 80-liter aquaria. Social behavior was observed for an extended time in daily observation periods. Individuals of G. bosci, regardless of size and sex, exhibited agonistic behavior. The aggresive behaviors of approaching, threatening, attacking, and fighting were recorded as agonistic behavior. All individuals are capable of changing their color and camouflaging themselves by matching the color of bottom. Especially, the resident and the intruder are of the same size, the fighting duration was prolonged and the variability of coloration was at its peak.

  • The estuarine Gobiidae $Tridentiger$ $trigonocephalus$, $Chasmichthys$ $dolichognathus$ and $Favonigobius$ $gymnauchen$ were exposed to various heavy metals. As a measure of acute toxicity, the 96h-$LC_{50}$ in the three species exposed to copper, lead, zinc and chromium was 740-990, 1,660-1,980, 6,180-8,490 and 8,830-11,296 ${\mu}gL^{-1}$, respectively. In order of toxicity, the heavy metals were ranked copper>lead>zinc>chromium. The Gobiidae $C.$ $dolichognathus$ was more sensitive to heavy metals than $T.$ $trigonocephalus$ and $F.$ $gymnauchen$.
