Egg development and early life history of Korean southern spine loach, Iksookimia hugowolfeldi, were observed in the present study. Eggs were obtained after injecting females with 0.5 mL/kg of Ovarprim. Eggs were artificially fertilized using the dry method in the laboratory. Number of spawned eggs ...

미꾸리과 어류란? | 미꾸리과(Cobitidae) 어류는 잉어목(Cypriniformes)에 속하며 유라시아와 아프리카 북부에 널리 분포하는 담수어류로 21속 171종이 보고되었고(Kottelat, 2012), 우리나라에는 5속 16종이 서식한다(Kim, 2009). 이 중 참종개속(Iksookimia)은 우리나라 고유속으로 참종개 I. | |
참종개속에 속하는 6종은? | 미꾸리과(Cobitidae) 어류는 잉어목(Cypriniformes)에 속하며 유라시아와 아프리카 북부에 널리 분포하는 담수어류로 21속 171종이 보고되었고(Kottelat, 2012), 우리나라에는 5속 16종이 서식한다(Kim, 2009). 이 중 참종개속(Iksookimia)은 우리나라 고유속으로 참종개 I. koreensis와 부안종개 I. pumila, 왕종개 I. longicorpa, 남방종개 I. hugowolfeldi, 동방종개 I.yongdogensis, 북방종개 I. pacifica 6종이 지리적으로 나뉘어서 서식하고 있다(Kim, 2009). | |
한국 고유종 남방종개의 난발생을 위한 인공수정 방법은? | 한국 고유종 남방종개 Iksookimia hugowolfeldi의 난발생 및 초기생활사를 밝히기 위하여 조사를 실시하였다. 성숙한 개체 복강에 Ovaprim (0.5 mL/kg)을 주사하여 12시간 경과 후 복부 압박법으로 채란하여 건식법으로 인공수정 시켰다. 산란된 난은 평균 $1,933{\pm}530$개로, 약한 점착성을 띤 밝은 노란색의 분리침성난이었으며, 난경은 $1. |
