We examined the effect of starvation on the occurrence of tunic softness to determine the cause of mass mortality of cultured Halocynthia roretzi (Drasche) in the Tongyeong region, Korea. In terms of the survival rate of H. roretzi and the occurrence rate of tunic softness, H. roretzi starved for 35...

한국에 분포하고 있는 멍게류의 종류는? | 우리나라의 전 연안에 분포하고 있는 멍게류는 약 20여종이 있으며(Hong, 2006), 이들 중 식용으로 활용되는 것은 멍게(우렁쉥이), 돌멍게, 붉은멍게, 주름미더덕, 개멍게, 미더덕 등이며. 이중에서 산업적으로 양식이 되고 있는 것은 멍게, 주름미더덕 그리고 미더덕으로 특히 멍게가 남해안과 동해안을 중심으로 많이 양식되고 있다. | |
국내의 멍게생산량의 추이는? | 멍게생산량은 2004년 7,464톤, 2010년에 6,300톤 및 2012년 9,030톤으로 2000년 이후 해마다 7,000-8,000톤 정도를 나타내고 있으며(KOSIS, 2013), 반면 멍게 폐사 현황은 2005년 57.6%, 2006년 68. | |
멍게 폐사의 원인은? | 5%으로 추정하고 있으며, 피해금액은 약 200억 원 이상으로 추정되고 있다(NEMA, 2012). 멍게의 폐사는 피낭이 연화되고 수관부의 수축반응이 감소하는 현상인 물렁증과 여름철에 주로 발생하는 쪼그랑증으로(Hur, 2009) 나타나고 있다. 이 가운데 대량 폐사의 주요인은 물렁증에 기인(Shin et al., 2011; Kim et al., 2012)하는 것으로 보고되고 있다. |
