The habitat characteristics and the age of endangered miho spine loach, Cobitis choii, were investigated in Ji Stream, Guem River, Korea in 2011 to provide baseline data for its restoration. The habitat of the C. choii was the downstream portion composed of sand, and the sand particle sizes was most...

당년생 치어와 성어의 서식지 분석 결과, 성어의 종간 차이점은 무엇인가? | , 2009), 줄종개(Ko, 2005), 북방종개(Ko, 2015)와 비교적 유사하였다. 하지만 성어의 경우는 Fig. 8과 같이 종간 차이를 보였는데, 미호종개의 수심은 35.6±16.2 cm로 나타나 기름종개와 점줄종개, 줄종개, 북방종개보다 매우 낮았으며(p<0.001), 반대로 유속은 16.1±9.17 cm/sec로 나타나 다른 종들보다 2~3배 빠른 특징을 보여 유의한 차이를 보였다(p<0.001). | |
미꾸리과 (Cobitidae) 어류의 특징은 무엇인가? | 미꾸리과 (Cobitidae) 어류는 저서성 소형어류로 유라시아와 아프리카 북부에 넓게 서식하고 21속 171종이 보고되었으며(Kottelat, 2012; Nelson et al., 2016), 우리나라에는 5속 16종이 서식하는 것으로 알려져 있다(Kim, 1997; Kim and Park, 2007; Kim, 2009). 이중 미호종개 Cobitis choii는 1984년 Kim and Son에 의해 신종 발표된 종으로, 우리나라에서는 금강에만 제한적으로 서식하고 국외에는 러시아의 아무르강에 서식하는 것으로 알려졌다(Kim and Park, 2007; Bogutskaya et al. | |
미호종개의 서식지의 특성은 무엇인가? | 멸종위기어류인 미호종개 Cobitis choii의 서식지 특성과 연령 등의 생태적 특징을 밝혀 보전학적으로 활용하기 위하여 2011년 금강 지류인 지천에서 조사를 실시하였다. 미호종개의 서식지는 하류부의 모래톱이 형성된 지역으로, 모래 입자 크기는 대부분 0.21~1.18 mm (88.7%)로 작은 편이었다. 치어는 수심이 5~20 cm로 낮고 유속은 0~15 cm/sec로 느린 곳에 주로 서식하고 있었지만, 1년생과 2년생, 3년생 이상의 개체들은 공통적으로 수심 20~50 cm, 유속 10~25 cm/sec의 느린 여울부에 서식하고 있었다. |
