The icthyofauna in the Kumho River was investigated from October 1990 to May 1991 and its community structures were analyzed. 35 species belonging to 26 genera and 9 families were collected. Of which 12 species are endemic species or subspecies in Korea. Among the species confirmed before a decade H. longirostris, C. brevicauda, P. esocinus, A. intermedia, C. roundicaudata and C. herzi were decreased in number markedly or were not collected P. altivelis and A. japonica do not migrate up now due to water pollution of the river. P. fulvidraco had not been collected at all after the report of Mori and Uchida(1934) but one individual was captured at ST 4(Banyawol) in this survey. Dominant species in main stream were R. uyekii, P. parva, Z. platypus, C. auratus, and S. gracilis majimae. On the contrary,. Z. temmincki, M. oxycephalus and M. anguillicaudatus dominated the tributries. The rare species less than 1% of all were 17 species. As a whole, dominant index was 0.085, diversity index 1.183 and evenness index 0.766. Thus it was supposed that the community structure of this river was stable and diverse relatively.

Electropherograms of the muscle myogens of the five Acheilgnathin fishes were obtained by the method of polyacrylamide slab gel electrophoresis. The result was compared each other and the relative similarities among species were determined. It was revealed that the fractional compositions of the muscle myogens were very complex. There were 24 to 26 protein fractions from species to species. The protein spectra of these fishes were species-specific and were distinguished each other by the numbers, mobilities and staining intensities of the fractions. Generally there was no variation in the electropherograms of the same species, but only in A. limbata a variation in the numbers of fractions was observed. In the genus Acheilognathus, there was 89% similarity between A. cyanostigma and A. yamatsutae, 62.5% between A. cyanostigma and A. limbala, 60.6% between A. yamatsutae and A. limbata. This corresponds with the morphological classification. However, there was 66.7 similarity between A. limbata and P. uyekii. This means that A. limbata may has much closer relationships to P. uyekii than to A. cyanostigma or A. yamatsutae.

The ichthyofauna and the structure of fish community were investigated in the Namgang-Dam reservoir, Jinju-city, Korea, and two streams drained into the dam from June to November in 1996. The ichthyofauna of study area was composed of 36 species, 27 genera belonging to 10 families. Of them cyprinid fishes occupied 61.1% (22 species) and cobitid fishes 13.9% (5 species). Dominant species at each station were as follows: Zacco temmincki and Squalidus chankaensis tsuchigae at St. 1, Acheilognathus koreensis and Zacco temmincki at St. 2, Lepomis macrochirus and Zacco platypus at St. 3 and Lepomis macrochirus and Cutter brevicanda at St. 4. Rare species were 12 species: Cyprinus carpio carpio, Cyprinus carpio nudus, Rhodeus uyekii, Acheilognathus yamatsutae, Acanthorhodeus asmussi, Hemibarbus longirostris, Sarcocheilichthys variegatus wakiyae, Pseudorasbora parva, Misgurnus anguillicaudatus, Misgurnus mizolepis, Cobitis rotundicaudata and Channa argus. Endemic species of Korea in this water basin were 13 species: Rhodeus uyekii, Acheilognathus koreensis, Acheilognathus yamatsutae, Squalidus gracilis majimae, Squalidus chankaensis tsuchigae, Sarcocheilichthys variegatus wakiyae, Microphysogobio yaluensis, Coreoleuciscus splendidus, Cobitis rotundicaudata, Niwaella multifasciata, Liobagrus mediadiposalis, Coreoperca herzi and Odontobutis platycephala. In the view point of indices of diversity and evenness, it seemed that the upper stream area had more diverse species composition and more stable structure than the dam area.

Ecological study on the bluegill, Lepomis macrochirus Rafinesque, was carried out with materials captured in Andong-Dam reservoir. Body length distribution of the bluegill showed that the population collected at July was composed of three year classes: two, three and four years-old classes, and of them two years-old fishes were the most abundant. Sex ratio of the female to male in the bluegill was 1:0.91 and the change of sex ratio by growth did not appear. The value of gonadosomatic index was the most high at July in both sex(Mean ♀: 8.64, ♂: 3.39). Fecundity of the bluegill which shown as the number of mature eggs was 520∼17,220. Bluegill ate frequently larvae of chironomid, shrimps, juvenile fishes and fish eggs. Individuals below 80mm standard body length ate chironomid larvae mainly but individuals above 80 mm ate shrimps and juvenile fishes.

The ichthyofauna and the ecological characteristics of fish community in the Kumho River were investigated from October 1990 to June 1993. 42 fish species belonging to 33 genera and 13 families were collected. Of all families, Cyprinidae(23 species, 54.8%) and Cobitidae(6 species, 14.3%) were the most abundant. Dominant species in the main stream were Rhodeus uyekii, Pseudorasbora parva and Carassius auratus. On the contrary, Moroco oxycephalus, Zacco temmincki and Squalidus gracilis majimae dominated in the tributaries. The rare species less than 1% of all collected individuals were 25 species(57.1%). Endemic species or subspecies in Korea were 14 species. Abbotina springeri was collected at St.4 and this is the first record in the Kumho River. The changes of species composition differed site by site but there were a tendency that Carassius auratus, Pseudorasbora parva, Rhodeus uyekii and Squalidus gracilis majimae which had some resiatancy on the pollution increased in number of individuals. There were monthly changes in community structures but it did not fluctuate largely as a whole. According to the dominant and diversity indices, it seemed that St.2 was the most stable community and St. 6, 10 and 11 were the most unstable communities. Diversity indices were maintained as higher values in the middle-upper reaches but the value was dropped rapidly in the lower reach. This means that the lower reach was polluted severely. These results show that the analysis of fish community does not reflect changing of environment over short period but indicates well the present state of water quality. Therefore, long-term monitoring on the dynamics of fish community is needed for the use of fishes in management of water quality.

The ichthyofauna and fish community structure at the downstream of the Hyongsan River were investigated from April 1991 to March 1992. The ichthyofauna was composed of 37 species and 31 genera belonging to 15 families. Of which three species, S. multimaculatus, R. uyekii and C. longicorpus were endemic species in Korea and two species, H. molitrix and L. macrochirus were transplanted fishes. The component species were markedly different between brackish and fresh water areas: in brackish water area 42.3% of collected fish were sea fishes but in fresh water area 75% were primary freshwater fishes. The diadromous fishes were 9 species; of which 5 species; Lateolabrax japonicus, Mugil cephalus, Tridentiger obscurus, Rhinogobius brunneus and Acanthogobius flavimanus were amphidromous, 3 species; Hypomesus olidus, Tribolodon hakonensis and Gasterosteus aculeatus were anadromous and one species; Anguilla japonica is catadromous. The dominant species were C. auratus, P. parva, P. sinensis kaibarae and M. oxycephalus in brackish water area. The rare species less than 1% of all were 14 species. As a whole, the dominance index was 1.113, diversity index 1.143 and evenness index 0.729. The dominance index was somewhat higher than that of other rivers in southern part of Korean peninsula but the community structure were rather stable and diverse.

The morphological characteristics of scales on Coreoleuciscus splendidus can be summarized as follows: 1. The longitudinal diameter on the scales of the tail part is longer than transverse diameter of it. 2. The scales having the largest diameters, both longtiudinal and transverse, are the lower third scale row (L₃). 3. The number of ridges in anterior radius is in proportion to longitudinal diameter. 4. The growth rate of all scales is rapid on posterior area than anterior. 5. The incompleted grooves are more than completed grooves.
