Abstract

The population ecology (Ecological characteristics) of Squalidus chankaensis tsuchigae were investigated at Geum River from March to November, 2013. This species inhabited midstream of the river where was mostly covered with cobble and sand. The depth of the habitat was 30~60 cm and velocity of stream was 2.27~4.88 cm/sec. The sex ratio of female to male was 1 : 0.86. They were sexually mature when they were over two years of age. The spawning period was from June to July with water temperatures from $25^{\circ}C$ to $25^{\circ}C$. Sexually matured individuals appeared over the two year of age. Frequency analysis of total length indicated that the group with 55~70 mm in total length was one year old, the 71~90 mm was two years old, and the group over 91 mm was three years old. The average number of eggs in the ovaries was estimated as 2,219 per matured female. The number of matured eggs size in ovaries was 0.64~0.98 (mean: 0.85) mm. Calulation length-weight relation of S. chankaensis tsuchigae show the value of contant a as 0.0002 and b as 2.81, and condition factor (K) was 1.06 on average. The stomach contents were Cyanophyta, Chlorophyta, Bacillariophyta, Crustaceae, Copepoda, Nematota, Actithocephala, and Ephemeroptera, Hemiptera, Diptera, and Trichoptera that belong to Aquatic insect, and dormant bud of Pectinatella that belongs to Phylactolaemata. The diet of S. chankaensis tsuchigae was omnivorous, mainly vegetable feed on attached algae (filament form), and mainly animality feeded on benthic invertebrates such as Chironomidae larvae.

참몰개(Squalidus chankaensis tsuchigae)의 개체군 생태 특성을 연구하기 위해 2013년 3월부터 11월까지 금강에서 조사하였다. 본 종은 하천 중류에 분포하며 하상구조는 주로 큰 돌과 모래로 이루어져 있었다. 서식지 수심은 30~60 cm이었고 유속은 2.27~4.88 cm/sec 상태를 유지하고 있었다. 암수의 성비는 1 : 0.86 이었고 산란시기는 6~7월로 수온은 $20{\sim}26^{\circ}C$이었다. 만 2년생 이상부터 성적 성숙이 이루어지기 시작했다. 전장이 40~69mm의 집단은 만 1년생, 71~89mm의 집단은 만 2년생, 90mm 이상은 만 3년생으로 추정되었다. 포란수는 평균 2,219개 이었고 성숙란의 직경은 0.64~0.98(평균 $0.85{\pm}0.042$)mm 이었다. 전장과 체중 관계식은 $BW=0.0002TL^{2.81}$로 상수 a는 0.0002을, 매개변수 b는 2.81이었고, 건강도는 평균 1.06 이었다. 먹이생물은 남조류(Cyanophyta), 녹조류(Chlorophyta), 규조류(Bacillariophyta), 갑각류(Crustaceae), 요각류(Copepoda), 선충류(Nematota), 구두동물(Actithocephala), 수서곤충(Aquatic insect)에 속하는 하루살이목(Ephemeroptera), 노린재목(Hemiptera), 파리목(Diptera), 날도래목(Trichoptera), 태형동물(Brtozoa) 피후강(Phylactolaemata)에 속하는 큰빛이끼벌레(Pectinatella) 등 이었다. 식성은 잡식성이었으며 식물성은 부착성이며 사상체를 형성하는 조류(Algae)가 대부분을 차지하였고 동물성은 깔다구(Chironomidae) 유충을 주로 섭식하였다.
