The monthly variations of blood characteristics and RNA/DNA of black sea bream, Acanthopagrus schlegeli, habituated in Geojae costal area were analysed to determine health condition of natural stocks in terms of gonad maturation and spawning season from March 2010 to February 2011. Spawning season d...

감성돔이란? | 감성돔, Acanthopagrus schlegeli (Bleeket)은 농어목(Order Perciformes) 도미과(Family Sparidae)에 속하는 내만성 어종으로 중국해 동남쪽, 일본 훗카이도이남 및 우리나라 전 연안 해역에 분포한다(Chyung,1977). 웅성선숙자웅동체(protandric hermaphoroditism)로서 수컷으로 먼저 분화한 후 약 3~4년이 지나면 암수로 구분이 되나 일부는 암수 한몸으로 수컷의 기능을 갖는 것도 있다. | |
감성돔의 암수변환은? | 감성돔, Acanthopagrus schlegeli (Bleeket)은 농어목(Order Perciformes) 도미과(Family Sparidae)에 속하는 내만성 어종으로 중국해 동남쪽, 일본 훗카이도이남 및 우리나라 전 연안 해역에 분포한다(Chyung,1977). 웅성선숙자웅동체(protandric hermaphoroditism)로서 수컷으로 먼저 분화한 후 약 3~4년이 지나면 암수로 구분이 되나 일부는 암수 한몸으로 수컷의 기능을 갖는 것도 있다. 4~5년부터는 완전히 분리되어 대부분 암컷으로 성전환을 하게 되고 산란기간이 약 3개월가량 지속되는 것으로 알려져 있다(Kinoshita, 1939; Gonzales 등, 2008). | |
핵산함량의 측정은 어떻게 진행하였나? | 핵산함량의 측정은 Clemmesen (1994)과 Belchier 등(2004)의 분석법을 변형하여 형광광도법으로 Microplate reader (Varioskan flash, Thermo Sci.)를 사용하여 측정하였다(Kim 등, 2005). 등지느러미 밑부분의 근육을 채취하여 동결건조한 후(-50℃, 24 hr), 무게를 측정하여 Tris-ethylenediaminetetraacetic acid (TE;5mM Tris-HCl, 0. |
