한국산 (韓國産) 흰수마자 Gobibotia naktongensis Mori 의 분포에 관하여
전상린,손영목 ( Sang Rin Jeon,Yeong Mok Son ) 한국하천호수학회 1983 생태와 환경 Vol.16 No.1·2
To clarify the ditributional districts, the authors have surveyed the micro-distribution of the Gobiobotia naktongensis Mori from Korea. And the results are as follows; 1. The authors have collected Gobiobotia naktongensis in the Euiryeong Gun, Habcheon Gun and Jinju City of the Naktong River, and Cheongwon Gun of the Miho River, tributary of the Geum River. In the collection of this species from Miho River is the first collection in the Geum River. 2. Above results did not agree with the studies of ditributional ditrict of Korean fresh-water fishes by Mori(1936) and Jeon(1980). Therefore there should be many studies and exeminations about the micro-distribution of Korean fresh-water fishes. 3. There should be many surveyes to clarify the ecological features about the Gobiobotia naktongensis Mori.

팔당호에 도입된 파랑볼우럭 ( Lepomis macrochirus ) 의 식성
변화근,송호복,전상린,손영목 ( Hwa Kun Byeon,Ho Bok Song,Sang Rin Jeon,Yeong Mok Son ) 한국하천호수학회 1997 생태와 환경 Vol.30 No.1
The authors investigated the diet of bluegill (Lepomis macrochirus) at Lake Paldang from November 1995 to August 1996. The food items of L. macrochirus consist of phytoplankton, zooplankton, plants, Mollusca, Annelida, Decapoda, Arachnida, aquatic insect, bryozoa, terrestrial insect, fish (Cyprinidae) and fish egg. Larger fish tend to ingest a higher proportion of the larger prey types, such as fish, fish egg, Odonata, Mollusca, Annelida, but younger year-class is more Zooplanktonic. The bluegill introduced into Lake Paldang shows dietary shift with wider food niche including piscivorous than that of bluegill with congeners in their home land.

열목어 ( Brachymystax lenok tsinlingensis ) 의 먹이선택 습성
변화근,조규송,최재석,박정호,최준길,손영목,전상린 ( Hwa Kun Byeon,Kyu Song Cho,Jae Suk Choi,Jung Ho Park,Jun Kil Choi,Yong Mook Son,Sang Rin Jeon ) 한국하천호수학회 1995 생태와 환경 Vol.28 No.3
We investigated diet of Manchurian trout(Brachymystax lenok tsinlingensis) at Jindong stream from October 1993 to August 1994. The stomach was U shaped with 57-69 Pyloric caeca. Gill rackers number externally on first gill arch was from 12 to 20, and premaxillary teeth with pointed was 24. The diet of B. lenok tsinlingensis was mainly acquatic insects, such as ephemeroptera, trichoptera, plecoptera, diptera, and nematoda, teleost fishes, land insects, amphibian and decapoda. Larger fish tended to ingest a higher proportion of the larger prey types, such as amphibian(frog), teleost fishes(Moroco kumgangensis, Ladislavia taczanowskii), nematoda(nematomorpha) and decapoda(crayfish), but younger year-classes to eat more Chironomidae. Land insects of the stomach contents was found mainly autumn. Aquatic insects(ephemeroptera, trichoptera and diptera) constituted the bulk of food items ingested during each season. The prey selection indices for ephemeroptera were positively selected in summer, and negatively selected in spring and autumn, plecoptera and trichoptera were positively selected in spring and negatively selected in summer and autumn. In contrast, diptera was always positively selected. B. lenoktsinlingensis classification of trophic categories is chaser.

孫永牧,田祥麟 西原大學校 基礎科學硏究所 1991 基礎科學硏究論叢 Vol.4 No.-
Fresh-water fish fauna of near the DMZ area of Kosong-gun, Kangwon-do was surveyed at 6 stations from July to August, 1990. Seven families, 12 sp. and subsp. were caught throughout the present survey, which were composed of 6 species(50%) of primary freshwater fishes and pheripheral fresh-water fishes respectively. Among them, Moroco sp. and M. semotilus were the endemic species of korea. Fish fauna in studied area was mostly composed of fishes belong to Northern origin, which was characteristic of the river system flow into the East Sea. The remarkable species of these area were Lampetra japonica, Oncornynchus masou, Moroco sp., M. semotilus, Cobitis granoei, and Cottus hangiongensis, which will be needed preservation. Total of 32 species of phytoplanktons were cellected and they were confirmed 25 species (78.1%) of Diatom, 4 species(12.5%) of Blue-green algae, and 3 species(9.4%) of Green algae.

치악산 계류에 서식하는 둑중개(Cottus poecilopus Heckel)의 식성
최재석,전상린,변화근,최준길,심하식,손영목 한국어류학회 1995 韓國魚類學會誌 Vol.7 No.2
둑중개(C. poecilopus)의 식성을 조사하기 위하여 치악산 계류에서 1993년 4월부터 1994년 3월까지 월별로 조사를 실시하였다. 조사된 위 내용물은 주로 수서곤충인 Ephemeroptera, Odonata, Plecoptera, Trichoptera, Coleoptera, Diptera이며 그 밖에 Nematoda, 치어, 어란, 육상곤충 등이 검출되었다. 육상곤충은 주로 가을에 섭취하였고, 여름에 Moroco oxycephalus 치어를 소량 포식하였다. 전반적으로 본 종의 먹이는 Ephemeroptera, Trichoptera, Diptera 등이 대부분이었다. Ephemeroptera는 여름에 양의 선택성을 나타내었고 가을과 겨울에는 음의 선택성을 나타낸 반면 Trichoptera와 Diptera는 가을과 겨울에 양의 선택성을 여름에 음의 선택성을 나타내었다. 또한 수컷이 수정란을 보호하고 있는 동안 먹이량이 부족하면 보호하고 있는 알을 먹는 습성이 있다(filial-cannibalism). The authors investigated feeding habit of river sculpin(C. poecilopus) were conducted at the Chiak streams from April 1993 to March 1994. The feeding habit of C. poecilopus was mainly acquatic insects, such as Ephemeroptera, Odonata, Plecoptera, Trichoptera, Coleoptera, Diptera, and Nematoda, teleost fishes, fish egg and terrestrial insects. Terrestrial insects in the stomach contents were found mainly in autumn, and teleost fish(Moroco oxycephalus) was in summer. Aquatic insects(Ephemeroptera, Trichoptera and Diptera) constituted the bulk of food items ingested during each season. The prey selection indices for Ephemeroptera were positively selected in summer, and negatively selected in autumn and winter, Tricoptera and Diptera were positively selected in autumn and winter, and negatively selected in summer. Additionally, analysis for stomach contents of guarding males suggests that the parental males eat their own eggs during egg guarding(filial - cannibalism).
