송호복,Song, Ho-Bok 한국상하수도협회 2004 한국상하수도협회지 Vol.5 No.-

우리들은 부모님의 자식 사랑에 대하여 잘 알고 있다. 그러나 사람을 포함한 대부분의 동물들이 부성애보다는 모성애가 훨씬 강한 것으로 알려져 있지만 물고기들은 예외라고 한다. 여기 무섭고 냉혈한 같이 생긴 녀석이지만, 자식사랑 만큼은 이 세상 어느 누구보다 절절한 둑중개의 부성애를 소개한다.

송호복,최신석 ( Ho Bok Song,Shin Sok Choi ) 한국하천호수학회 1997 생태와 환경 Vol.30 No.1

The mature adults of Moroco kumgangensis were collected from the upper South-Han river at Dong-myon, Chungsun-gun, Kangwon-do on April 1996 and fertilized eggs were reared to observe the developmental characters and the morphology of larvas at water temperature of 16±1℃. The eggs were globosity, yellowish brown, submergence and adhesive type and diameter of the eggs were 2.31±0.094 mm after absorption of water. Cleavage was progressed at intervals of an hour and five minutes after fertilization, and optic cup and somites (18∼22) were observed in sixty three hours. In ninety six hours, the number of heart beat was 40 times/min. and movement of embryos was active. Hatching began about five days after fertilization and the newly hatched larvae were 5.28±0.453 mm in total length and the number of heart beat was 44 times/min. Melanophore appeared within three days after hatching and the larvae were 11.05±0.389 mm in total length and reached the free swimming stage in ten days after hatching. In twenty five days, the number of heart beat was 162 times/min, dorsal, anal and caudal fin rays were 7, 7 and 25∼30 respectively and reached 11.92±0.275 mm in total length.

송호복,권오길 ( Ho Bok Song,Oh Kil Kwon ) 한국하천호수학회 1994 생태와 환경 Vol.27 No.2

This study was described squamation chronology and scale morphology of the bitterling, Acheilognathus yamatsutae. The first scale appeared on the caudal peduncle region at 11.4±0.18mm and the final squamation was completed at 16.5±0.34mm in standard length. The height of the scales on anterior region was longer than width of it and the height increased to predorsal region and decreased in posterior region. The largest scales were center of lateral line scales and the number of circuli in each scale increased proportionately to the height to scale. Regeneration scales were average 20.9% in lateral line, 3 rows of above the lateral line and 2 rows of below the lateral line scales. The scales below the lateral line were observed many regeneration scales than the scales above the lateral line.

줄납자루 , Acheilognathus yamatsutae 의 지리적 변이 및 Acheilognathus cyanostigma 와의 형태비교

송호복,권오길 ( Ho Bok Song,Oh Kil Kwon ) 한국하천호수학회 1994 생태와 환경 Vol.27 No.2

In this study the geographic variation of Acheilognathus yamatsutae from five river system in Korea was investigated and a morphological comparison between A. yamatsutae and Acheilognathus cyanostigma was conducted. Morphological variation of A. yamatsutae was very diverse among populations. Of all characters, barbel length showed great difference. Barbel length of the Nagtong river population was the shortest of all populations. There were no morphological difference between sex. A. yamatsutae was clearly discriminated from A. yamatsutae by the following characters: barbel length, egg shape and the number of scales above lateral line. In cluster analysis, A. yamatsutae divided into two groups. The one is composed of the Nagtong river population and the other is composed of the Han, Kum, Somjin, Youngsan river populations. A. yamatsutae from Japan showed very distant relationship with A. yamatsutae from Korea.

송호복,권오길 ( Ho Bok Song,Oh Kil Kwon ) 한국하천호수학회 1993 생태와 환경 Vol.26 No.3

This study was made to expand the knowledge of the ecology of Coreoleuciscus splendidus Mori in the upper part of Hongchon river from Feb.1989 to Oct.1990. This species was found at the upper and middle parts of stream in clear and rich dissolved-oxygen water and the habitat was stones and pebbles bottom. The flow velocity was 57±23cm per second and the water depth was 23±6cm. The major cohabitation fish were Zacco temmincki, Pungtungia herzi and Coreoperca herzi. The body length frequencies in this population indicated that 35-5Smm group is one year old, 55-7Omm group is two years old and the longer group than 70mm is regarded as being over the three years old. The male and female individuals became sexually mature over the two years old and the spawning season was from early April to late May with water temperature 10-l8˚C and the properous season was early May in 15˚C. The mean number of eggs was 1132 and the eggs were sink, adhesive stickiness, opaque and the size after absorption of water were 2.24±0.07mm, and the micro-villi were dense on the surface of the egg under the SEM microscope. The sex ratio of male and female was 1.73: 1, and the contents of stomach were almost aquatic insects including Baetis sp.

맑은 물 계곡의 토종 4총사

필자는 때때로 물고기를 관찰하기 위해 산으로 간다. 차도 들어가지 못하는 험한 산길을 굽이굽이 돌아 산간 계곡에 이르면, 한 여름에도 발을 담그지 못할 만큼 찬 물이 흐르는 곳에서 세찬 물살과 함께, 시퍼런 웅덩이와 깨끗하게 닦인 돌들이 나타난다. 그리고 그런 곳을 터전으로 삼아 살아가고 있는 우리의 토종 친구들을 만날 수 있다.

저 깊은 계곡, 차고 깨끗한 물 속에 열목어와 산천어가 있다!

일반인들은 BOD나 COD가 몇 ppm 쯤 되어야 1급수인지, 또는 DO의 농도는 얼마나 되어야 2급수가 되는지 알고 있을까? 그 숫자들을 기억하는 사람들은 별로 없을 것이다. 그러나 집 앞에 흐르는 냇물이 1급수인지, 2급수인지 쉽게 판별하는 아주 좋은 방법이 있다. 바로 지표생물을 통해서이다. 어떤 환경에 서식하면서 그 환경의 상태를 나타내는 생물들을 지표생물이라 하는데, 수환경도 마찬가지로 금강모치나 플라나리아가 살면 1급수, 피라미는 2급수, 붕어나 잉어가 살면 3급수, 실지렁이가 살면 4-5급수 등으로 구분할 수 있다.

본 연구는 국내 수계에 심각한 위해를 가하고 있는 블루길의 효과적인 관리방안을 위한 기초 자료를 제공하고자 하였으며, 한강수계에 서식하는 개체군을 대상으로 2009년부터 2012년 사이에 연구를 실시하였다. 한강수계에 위치한 대부분의 댐호에는 불루길이 출현하였으며 하천의 경우 하류역에 국한되어 서식하였다. 각 댐호의 개체수 상대풍부도는 0.2~18.2%의 범위였으며 대부분의 댐호에서 아우점종이거나 우세종에 속하였다. 생체량 상대풍부도는 0.2~40.0%였다. 개체군 동태는 소양호와 팔당호는 r-전락형, 의암호와 청평호는 K-전략형, 충주호는 K-전략형에서 r-전략형으로 이행하는 단계로 판단되었다. 비만도와 체중 전장의 관계는 모두 양호한 상태를 나타내었다. 산란장은 집단을 형성하여 조성하였으며 산란둥지의 직경은 평균 42.14cm, 깊이는 평균 9.7cm였고, 둥지가 위치한 평균 수심은 56.3cm, 수변으로부터의 거리는 평균 191.9cm이었다. 본 연구결과는 향후 블루길의 개체군 동향 예측과 번식생태 등을 파악하는데 유용한 자료가 될 것으로 본다. This study was examined for information of management of bluegill, Lepormis macrochirus which is disturbance species of underwater ecosystem in Korea. Research of bluegill population was investigater spring-summer and autumn periods in the Han river system from 2009 to 2012. Bluegill inhabited mostly lakes,and restrictedly lived at still area in downstream. The range of relatibe abudance were 0.2~18.20% in individual number an 0.2~40.0% in biomass and it was subdomiant or superiority species for the most part of the lakes. Population structure were analyzed r-strategy in Lake Soyang and paldang and K-strategy in Lake uiam and Cheongpyeong. but Lake Chungju was estimated transi-tion period from K-strategy to r-strategy. Condition factor and body weight-total length relations were presented favorable condition. For the nesting, bluegill was formatted the group. Adn the water depth and the distance from shore were mean 56.3cm and 191.9cm respectively in nesting ground. Diameter and depth of nests were mean 42.4cm and 9.7cm respectively. These results are available for research of population dynamics and reproductive ecology of bluegill.
