여울마자의 특징은 무엇인가? | 이 중 여울마자는 돌마자와 형태적으로 매우 유사하나 산란기 체색의 차이와 윗입술 피질돌기의 수, 측선상부 비늘수, 항문에서 뒷지느러미 기점까지의 거리 등이 형태적 차이가 나타나며, 생물 지리적으로 낙동강에만 제한적으로 분포하는 점을 들어 독립된 종인 여울마자로 신종 보고되었다 (Chae and Yang, 1999). 본 종은 최근 서식지 개발과 환경 오염 등으로 개체수가 급감하고 있어서 환경부는 2012년 멸종위기 야생생물 I급으로 새롭게 지정하여 보호하고 있으며 (ME, 2012), 한국의 멸종위기 야생동·식물 적색자료집 (Red Data Book Endangered Fishes in Korea)에서는 위급 (Critically Endangered, CR)종에 해당되었음에도 불구하고 (NIBR, 2011) 환경부의 전국자연환경조사 (ME, 1997~ 2008)의 출현기록, 모래주사속 어류의 재검토 (Kim and Yang, 1999) 및 버들매치속 Abbottina과 모래주사속 어류의 분자계통학적 연구 (Kim and Bang, 2010) 등 주로 계통분류학적 연구에 한정되어 있을뿐 초기생활사를 포함한 기타 연구는 전무한 실정이다. | |
Microphysogobio란 무엇인가? | 잉어과 Cyprinidae 모래무지아과 Gobioninae에 속하는 모래주사속 Microphysogobio 어류는 주로 동아시아에 분포하고 있 으며, 소형의 저서성 1차 담수어류이다 (Uchida, 1939; Cheng and Zheng, 1987; Howes, 1991; Banarescu, 1992). 우리나라에는 배가사리 M. | |
우리나라 Microphysogobio 어류는 무엇이 있는가? | 잉어과 Cyprinidae 모래무지아과 Gobioninae에 속하는 모래주사속 Microphysogobio 어류는 주로 동아시아에 분포하고 있 으며, 소형의 저서성 1차 담수어류이다 (Uchida, 1939; Cheng and Zheng, 1987; Howes, 1991; Banarescu, 1992). 우리나라에는 배가사리 M. longidorsalis, 경모치 M. jeoni, 모래주사 M. koreensis, 돌마자 M. yaluensis, 여울마자 M. rapidus 5종이 서식하는 것으로 알려져 있다 (Kim and Yang, 1999; Kim and Park, 2007). |
