한국산 가시고기(Pungitius sinensis : Gasterosteidae)인판(鱗板)의 지리적 변이

양홍준,채병수 한국어류학회 1989 韓國魚類學會誌 Vol.1 No.1

休戰線 이남의 韓半島에서 채집된 가시고기 P. sinensis의 12 개체군에 대하여 鱗板의 수 및 형태의 지리적 변이를 조사하였다. 鱗板의 수에 地理的 傾斜는 보이지 않았지만 P. sinensis sinensis가 P. sinensis kaibarae 보다 다소 더 많이 나타나고 있어 두 亞種 간에 변이폭이 달랐으나 형산강 개체군은 매우 심한 변이를 나타내고 있었다. 鱗板의 크기는 금호강의 개체군이 가장 컸다. 형산강 개체군의 것은 크기도 작고 매우 퇴화적인 경향을 나타낼 뿐 아니라 semiarmatus型의 鱗板排列을 지닌 개체도 발견되고 있어 P. sinensis의 특수형으로 취급하였다. 陸封化와 鱗板의 크기 사이의 관계에서 보아, 형산강의 개체군이 가장 먼저 陸封化되었으며, 금호강의 개체군을 제외한 다른 P. sinensis kaibarae 개체군들은 보다 늦은 시기에 陸封化되었을 것으로 생각된다. 그러나, 陸封化되어 있으면서 내륙 깊이 존재하고 있는 금호강의 개체군이 가장 잘 발달된 鱗板을 지니고 있으며 鱗板의 수도 적지 않다는 사실에서, 이 개체군에는 鹽分耐性 및 陸封化와 鱗板의 수 및 발달이 서로 관계가 없음을 의미한다. 이러한 여러 사실로 보아 형산강과 금호강에 서식하고 있는 P. sinensis kaibarae 사이의 관계에 대해서는 보다 세밀한 조사가 요망된다. The geographic variations of the number and morphology of scutes of eightspine stickleback, Pungitius sinensis, in the southern half of the Korean peninsula were investigated. The two subspecies, P. sinensis sinensis and P. sinensis kaibarae, showed a bit of difference in the number of scutes but there was no geocline as a whole. In the frequencies of individuals with the different number of scutes between the left and right body side, there was also difference between the two subspecies, and the specimens from the Hyongsan River showed great variation. The populations of Kumho River had the largest scutes. But the specimens of the Hyongsan River had small and degenerated scutes different from all other populations, and some individuals showed the semiarmatus type arrangement of scute. Therefore, this population may be called the special type of P. sinensis. In the relationship between the time of landlocking and the size of scutes, it was speculated that the population of the Hyongsan River was landlocked long years ago and other populations of P. sinensis kaibarae except the Kumho River were landlocked more recently. For the population of the Kumho River, however, it seemed that there was no relation between salt tolerance or landlocking and number or developmental state of scutes as this landlocked population had well developed and large number of scutes.

대도시 주변 하천수계의 수질환경과 육수생물학적 연구 - 금호강수계의 (琴湖江水系0 어류상과 어류군집구조 (Ⅱ) -

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.

양홍준,채병수,강영훈 한국어류학회 1998 韓國魚類學會誌 Vol.10 No.1

낙동강 중류의 지류인 위천에서 어류상과 서식상황을 1995년 8월에서 1997년 10월까지 약 2년에 걸쳐 조사한 결과를 요약하면 다음과 같다. 본 조사의 결과, 모두 10과 30속 40종의 어류가 채집되었다. 그 중 잉어과 어류가 26종(65.0%)으로 가장 많았고, 다음은 기름종개과 어류가 5종(12.5%), 동자개과 어류가 2종(5.0%)이었고 나머지는 1종씩으로 이루어져 있었다. 한반도 고유종은 Rhodeus uyekii를 비롯한 16종으로 전체 어종수의 40%를 차지하여 매우 높은 고유성을 나타내었다. 하천 전체로 보면 Zacco temmincki(15.46%), Zacco platypus(14.29%), Squalidus gracilis majimae(11.25%)의 3종이 우점종이었으며, Cyprinus carpio, Rhodeus ocellatus, Culter brevicauda, Misgurnus mizolepis, Leiocassis ussuriensis, Silurus asotus, Macropodus chinensis, Channa argus의 8종은 상대풍부도가 0.1% 미만인 희소종이었다. 지역별 종조성을 보면 상류에서는 Moroco oxycephalus, 중상류에서는 Zacco temmincki, Squalidus gracilis majimae 및 Niwaella multifasciata, 중하류에서는 납자루류와 Zacco temmincki, 하류에서는 Zacco platypus와 Microphysogobio속 어류가 우세하게 나타났다. 군집구조의 분석은 본류의 중류인 St.9, 10, 11과 쌍계천의 중류인 St. 17, 18, 19의 6지점이 가장 안정되고 다양한 군집의 구조를 지니고 있으며, 상류인 St. 1과 4는 소수의 어종이 지배하고 있는 다양성이 낮은 군집구조를 지니고 있음을 나타내고 있다. The ichthyofauna and the structure of fish community were surveyed from August 1995 to October 1997 at twenty one stations in the Wicheon river which is a first tributary located at the middle reach of the Nakdong river system. During the surveyed period, 40 species belonging to ten families were collected. Of them cyprinid fish occupied 65.0% (26 species) and cobitid fish 12.5% (5 species). Sixteen species (40.0%) were known as Korean endemic species. Dominant species were Zacco temmincki (15.35%), Zacco platypus (14.12%), and Squalidus gracilis majimae (11.32%). Rare species which occupied less than 0.1% of total individuals were Cyprinus carpio, Culter brevicauda, Misgurnus mizolepis, Cobitis rotundicaudata, Leiocassis ussuriensis, Silurus asotus, Macropodus chinensis, and Channa argus. A tendancy were shown in regional distribution that Moroco oxycephalus dominated in upper stream, Zacco temmincki, Squalidus gracilis majimae, and Niwaella multifasciata in mid - upper stream, acheilognathid fishes and Zacco temmincki in mid - lower stream, and Zacco platypus and microphysogobioid fishes in lower stream. St. 9, 10, and 11 which located in mid - reach of main stream and St. 17, 18 and 19 which located in mid - reach of the Ssanggye stream had the most stable and diverse community structure.

양홍준,채병수,남명모 ( H J Yang,B S Chae,M M Nam ) 한국하천호수학회 1991 생태와 환경 Vol.24 No.1

The ichthyofauna in autumn at the upper reach of Hongchon River (a second tributary of Han River) was investigated and their community structures were analyzed. Twenty four species of fish (nineteen genera belonging to eight families) were collected in this area. Of these fishes ten species and two subspecies were endemic in Korea. This area become a new distribution site of Odontobutis obscura interrrupta. As a whole Zacco temmincki and Zacco platypus were dominant and bottom dwelling species that is Microphysogobio yaluensis and Odontobutis platycephala were also numerous. The species diversity index, dominance index and evenness index on the community of the upper reach of Hongchon River were 1.163, 0.086 and 0.843, respectively. The result indicate that the community structure of this area was very diverse and stable in species composition.

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.

안동댐의 파랑볼우럭 , Lepomis macrochirus Rafinesque 의 생태학적 연구

양홍준,채병수 ( Hong Jun Yang,Byung Soo Chae ) 한국하천호수학회 1997 생태와 환경 Vol.30 No.2

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 object of this study is to compare the shock isolation characteristics of the commercially available rubber washers due to the difference in a tightening torque and hardness. Drop impact test using a steel ball which can simulate the pyroshock acceleration was devised. The test results show that silicon had the highest shock isolation performances followed by urethane, nitrile showed the least performances. In addition, the test results show that the smaller a tightening torque and hardness, the shock isolation characteristics are improved. And this study propose an analysis method using the shock transmissibility function in order to minimize some uncertainty of the impact excitation in the shock response spectrum analysis.
