송호복 한국어류학회 2000 韓國魚類學會誌 Vol.12 No.2

Population ecology of Rhynchocypris keumgangensis have been investigated at upper part of the Han River in Korea from January to December, 1995. The habitat was low water temperature and clean area, and stream form was Aa. The major cohabitation fish was Phoxinus phoxinus. The total lengths in this population indicated that below 40㎜ group is one year old, 40∼65㎜ group is two years old, 65∼80㎜ group is three year and the 80㎜ longer group is regarded over four years old. There were no differences in total length distribution between the female and the male. The males became sexually mature, when longer than 45㎜ and females longer than 65㎜ in total length. Spawning season was from April to mid May with the water temperature in 11∼14℃ and the properous period was April. The mean number of eggs in ovary was 1,616. The sex ratio all the year round of the female to the male was 1 : 0.75. The current velocity of the spawning ground was 44(20∼80)㎝/sec and water depth was 35(5∼70)㎝. Eggs were laied in 5∼15㎝ deep underneath the immaculate pebbles (2∼6㎝). Sex ratio of the female to the male was 1 : 6.90 for spawning behavior.

송호복,백현민,조동현 강원대학교 기초과학연구소 2003 기초과학연구 Vol.14 No.-

Reproductive ecology of Odontobutis interrupta have been investigated in the Han river and the Imjin river, Korea from 2001 to 2003. The habitat was pool area of the middle or lower part of the stream. The major cohabitation fishes were Rhynchocypris oxycephalus, Zacco platypus and Rhinogobius brunneus. Spawning season was from May to June with the water temperature in 18~25℃ and the prosperous period was May (18~21.5℃). The current velocity of the spawning ground was 0~30 cm/sec and water depth was 39.8±10.262 cm (25~62 cm, N= 15). Mature male made the nest and had territory. The male leaded the female in the nest and spawning with reverse posture. After the spawning, the parental male guarded the eggs until hatch (nesting(♂) - lead(♂) - follow(♀) - spawning(♀) - ejaculation(♂) - guard(♂)).

송호복,손영목 한국어류학회 2005 韓國魚類學會誌 Vol.17 No.1

Osteolgical development of Korean striped bitterling, Acheilognathus yamatsutae (Cyprinidae), were investigated using cartilage and bone staining. The parasphenoid, dentary, pterygoid, ceratohyal, branchial arch and parts of the caudal skeleton were formed first as cartilaginous elements at 6.82±0.08 mm total length (TL). Formation of frontal, parietal, and maxillary were notable at 7.76±0.09 mm TL, and the proximal radial, scapula,and coracoid in the pectoral girdle were developed at this stage. At the same time, the neural and hemal spine were present in the caudal vertebra. The opercle and branchiostegals were observed at 9.68±0,14 mm, and the posttemporal was formed at 12.9±40.64 mm TL, respectively. Ossification in the parasphenoid, pharyngeal bone, dentary, premaxillary, maxillary, and opercle began at about 9.68±0.14 mm TL. The cleithrum, supracleithrum, urostyle, and caudal fin were calcified at this stage. The vertebral column was formed and ossified at 11.52±0.13 mm TL, and the frontal, preopercle, subopercle, and hyomandibular were ossified at 15.30±0.68 mm TL. This fish was late in developing the skeletal formation and ossification as compared with ther fishes. (dentary), 익상골 (pterygoid), 각설골 (ceratohyal), 새궁(branchial arch) 등과 미골 (caudal skeleton)의 일부 등이 생성되었다. 7.76±0.09 mm에는 전두골 (frontal)과 두정골 (parietal)의 발달이 현저하였고, 주상악골 (maxillary)이 나타났으며, 흉대 (pectoral girdle)의 방사기골(proximal), 견갑골 (scapula), 오훼골 (coracoid)이 형성되었다. 또한 신경극 (neural spine)과 혈관극 (hemal spine)이 미추(caudal vertebrae)에 생성되기 시작하였다. 9.68±0.14 mm에 내장골 (vesceral skeleton)의 주새개골(opercle)과 새조골 (branchiostegals)이 나타났으며, 12.94 mm에는 흉대의 후측두골 (post temporal)이 생성되었다. 골격의 골화는 9.68±0.14 mm를 전후하여 일어났으며, 부설골, 인두골 (pharyngeal bone), 치골, 전상악골(premaxillary), 주상악골, 주새개골 등과 늑골 (pleuralrib), 신경극, 혈관극이 골화되었으며, 흉대의 의쇄골(cleithrum)과 상의쇄골 (supracleithrum) 그리고 미골의 미부봉상골 (urostyle)과 꼬리지느러미 (caudal fin)가 골화되었다. 11.52±0.13mm에는 척추골이 생성되면서 골화되었고, 15.30±0.68 mm에 두부의 전두골, 전새개골(preopercle), 하새개골 (subopercle), 설악골 (hyomandibular)등이 경골화되었다. 본 종의 골격 형성과 골화는 다른 어종에 비하여 비교적 늦게 발달하였다.

한강수계의 섬강, 송천 및 홍천강 상류에서 M. longidorsalis의 서식지 환경과 개체군 생태를 연구한 결과는 다음과 같다. M. longidorsalis의 주된 서식지는 Aa 또는 Aa-Bb형 하천의 여울지역으로 주된 동서 어류는 Z. temmincki, Z. pltypus. P. herzi, C. Splendidus 등이었다. 전장 70㎜ 이하군은 만 1년생, 70~110㎜군은 만 2년생, 110㎜ 이상군은 만 3년생으로 분석되었다. 본 종은 암수 모두 만 2년생군 중 전장 80㎜ 이상이 되어야 성적으로 성숙하여 생식 능력을 갖는 것으로 나타났다. 산란기는 4월부터 5월까지(수온 : 15~17℃)로 조사되었으며, 산란 성기는 4월로 추측되었다. 평균 포란수는 7,334개였으며, 큰 개체일수록 포란수가 증가하는 경향(y = 200.32_(TL) - 11693, R^(2) = 0.6916)을 나타내었고, 난소 안의 성숙난의 크기는 1.03±0.072㎜였다. 성비는 1:0.87로 암컷이 조금 우세하였다. 주된 먹이 생물은 부착조류였으며, 전장에 다른 먹이 생물의 구성에는 큰 차이가 없었다. Population ecology of Microphysogobio longidorsalis was investigated in the upper part of the Han River in Korea from 1993 to 2003. The habitat was a current area, and stream form was Aa or Aa-Bb. The major cohabitating fishes were Zacco ternrnincki, Zacco platypus, and Pungtungia herzi. The total lengths in this population indicated that the below 70 ㎜ group is one year old, the 70-110㎜ group is two years old, and the group longer than 110 ㎜ is over three years old. Males and females became sexually mature at sizes longer than 80 ㎜ total length. The prosperous spawning season was April to March with the water temperature at 15-17℃. The mean number of eggs in the ovaries was 7,334. The mean mature egg size was 1.03f0.072㎜. The sex ratio all the year round of female to male was 1 : 0.87. Stomach contents were mainly phytoplankton.

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.

송호복,손영목 한국어류학회 2002 韓國魚類學會誌 Vol.14 No.4

Maturity and reproductive ecology of Phoxinus phoxinus were investigated in the upper part of the South Han river in Korea from January to December, 2001. The habitat was characterized by low water temperature and a bottom structure of boulders, cobbles and pedbbles. The major cohabitation fish were Rhynchocypris kumgangensis and R. steindachneri. The total lengths in this population indicated that the below 40 ㎜ group is immature, the 40~65 ㎜ group is one year old, the 65~85 ㎜ group is two years old and the longer group than 85 ㎜ is over three years old. There were no differences in total length distribution between females and males. Males became sexually mature at 50 ㎜ and females at 65 ㎜ total length. Prosperous spawning season was April with the water temperature at 10~12℃. The mean number of eggs in the ovaries was 1.280. The sex ratio all the year round of females to males was 1:0.85. The current velocity of the spawning ground was 26~58 ㎝/sec and water depth was 12~70 ㎝. Eggs were laid underneath the immaculate pebbles. During spawning, the sex ratio was 1:3.83(females : males).

衣巖湖에 棲息하는 줄납자루(Acheilognathus yamatsutae Mori)의 産卵 및 發生 特性에 關 한 硏究

송호복,권오길 江原大學校 附設 環境硏究所 1989 環境硏究 Vol.6 No.-

This study was made to expand the knowledge of the relationships between the mussels and the bitterlings (Acheilognathus yamatsutae Mori) and the materials were collected in lake Uiam from Mar. 1987 to Oct. 1988. The female fish has developed a prominent ovipositor and the male sidplayed a nuptial color during reprodductive period from the late April to August. The territory-defending behavior was four types and the extent of territory was about 60cm in diameter and 30cm in height. The mussel was the most important factor to stimulated the reproductive behavior rather than male and female. The number of total mean egfs in a fish was 300 and the mean egg size was 1.97mm in length and 1.74mm in breadth of ovoid shape. The preference of the oviposition of fish to the messels was order of Unio douglasiae, Lamprotula gottschei, Anodonta fukudai and A. woodiana. The egg began to hatch approximately 33 hours after insemination and reached the free swimming stage within 22 days after insemination at water temperature 25±1℃. The sex ratio of the male to the female was 1:1.73 and approached to an adult-shaped fish from about 40mm of body length. The contents of stomach were the algae and zooplanktons.
