  • The taxonomic review of the family Triglidae was made based on the specimens collected from the south-western coasts of Korea from 1986 to 1999. The family Triglidae from Korea was classified into 10 species belonging to 3 genera: Pterygotrigla hemisticta, Chelidonichthys kumu, Lepidotrigla, japonica. L. guentheri, L. alata, L. kishinouyei, L. kanagashira, L. microptera, L. hime and L. abyssalis. Of them, L. kanagashira was reported for the first time in South Sea of Korea. A key to species of the family Triglidae from Korea was provided, with description of their morphological characteristics and their distribution.

  • Comparison of morphological characters and development of eggs and larvae of two bitterlings, Acheilognathus limbata and A. signifer from Korea were observed and discussed taxonomically. A. signifer differs from A. limbata by the color pattern of dorsal and anal fin ray of male, egg form and the length of ovipositor of female. Although two species are overlapping each other in some morphometric characters, there is a great difference between the two in the multivariate analysis of 15 morphological characters of five comparative populations. These results indicate that A. limbata and A. signifer are two independent allopatric sibling species in Korea.

  • An experiment was conducted for 80 days to determine the effect of feeding and starvation on the survival, growth, gonad-somatic index (GSI), hepato-somatic index (HSI), viscera index (LSI), the morphometric changes and hematological parameter in a cultured catfish, Silurus asotus. The survival and growth of the starved group was lower than those of the fed group during the experiment. Starvation resulted in retardation of growth, which provides examples of the reduction of final body weight, growth rate of body weight, specific growth rate and condition factor, whereas the fed group continued to grow and remained in good condition. Blood analysis (cortisol, glucose, aspartate aminotransferase, alanine aminotransferase, red blood cell and hemoglobin) showed significant differences between the fed and starved groups at the end of the experiment. These results suggest that all nutritional parameters used for starvation and feeding in this study appear to be a useful index of nutritional status in the cultured catfish.

  • Morphometric analysis of Lycorma delicatula was performed to confirm whether local individuals had a geographical difference in their wing variations. The L. delicatula individuals were collected from 10 localities in Korea, China, and Japan, and 14 morphometric characteristics selected from the forewing were analyzed. The Korean individuals were similar to the ones from the northern area of the Yangtze River, but less similar to the others from the southern area of the Yangtze River. The individuals from Seoul and Buan were very similar to those from Shanghai. In case of wing spots, the individuals from Beijing had relatively small spots, while the ones from Linan had big spots. The Japanese individuals had a relatively large wing size.

  • Morphological variation of the crusian carp, Carassius auratus, from Yongnam area in Korea was examined. In morphometric and meristic characters, mean values were different slightly among the polulations, whereas the range of variation was overlapped largely. In the present examination the number of spines in dorsal fin were 4-6. The majority of individuals appeared to be similar to Carassius auratus langsdorfii from Japan, but some individuals were quite different from them in having 66-83 gill rakers.

  • Pleurogrammus monopterygius was first collected from Daejin-ri, Goseong-gun, Gangwon-do, Korea on April 1999. This species is distinguished from its related species by having four to five broad blackish bands on the side of its body and different patterns of lateral lines. We gave P. monopterygius the new Korean name, "Dan-Gi-Im-Yon-Soo-Eo" and described the species in detail based on the study of specimens.

  • 한국특산종인 Colitis rotundicuudutu의 지리적 변이를 전국 5개 집단 132개체를 대상으로 조사하였다. 4개 집단의 계측형질로 본 다변량분석 결괴 산청집단은 타 집단과 형태적 차이가 있었다 전기영동으로 조사된 5개 집단의 평균 유전적 변이 정도는 A=1.48, P=37. IpA, HD=0. 139, 및 H6=0. 124로 변이 정도가 타 어류에 비하여 비교적 높았다. 5개 집단의 평균 유전적 근인치(S)는 0.83으로 낮았으나 산청집단을 제외한 4개 집단의 근연치는 0. 91로 매우 가까웠다. 반면 산청집단은 나머지 집단과 형태적으로나 유전적으로 유의한 차이가 나타나는 것으로 보아 산청집단의 별종 가능성이 매우 높음을 시사한다. 앞으로 보다 면밀한 연구로 산청집단의 별종 여부를 명백히 구명하여야 할 것이다.

  • Based on a single juvenile specimen (32.3 mm SL) collected from the northeastern coastal waters of Goseong, Gangwon-do, Nautichthys pribilovius was described as the first juvenile record from Korea. This juvenile fish is characterized by having entire body covered with close-set villous prickles, a blunt triangular ridge above orbit with a palmate cirrus, two blunt occipital projections, preopercle with four blunt spines, and a blackish bar below eye reaching lower margin of preopercle. Some morphometric characters related with growth were also discussed.
