We investigated the occurrence of the dinoflagellate genus Alexandrium in the nineteen Korean coastal sites from July to October 2013. Alexandrium-like planktonic cells were microscopically observed only in four out of the 19 sampling sites. From the samples containing Alexandrium-like cells 22 clon...

적조란 어떤 현상인가? | 해양생태계에서 발생하는 다양한 현상 중에 하나인 ‘적조(red tides)’는 플랑크톤 등이 일시에 다량으로 증식되거나, 물리학 작용으로 일정 지역에 집적되어 해수의 색을 변색시키는 현상을 말 한다(ECOHAB, 1995). 이러한 적조 생물의 증식과 집적은 수중의 용존 산소를 고갈시켜 다른 생물의 생존을 저해하며(Hallegraeff, 1993), 규조류와 더불어 적조원인의 주된 그룹을 형성하는 와편모류의 일부는 독성을 함유하고 있어, 해양 먹이망을 교란시키고, 어패류를 독화 시키는 등의 생태계 균형 붕괴의 원인이 된다. | |
적조 생물의 증식과 집적은 생태계적으로 어떤 문제를 야기하는가? | 해양생태계에서 발생하는 다양한 현상 중에 하나인 ‘적조(red tides)’는 플랑크톤 등이 일시에 다량으로 증식되거나, 물리학 작용으로 일정 지역에 집적되어 해수의 색을 변색시키는 현상을 말 한다(ECOHAB, 1995). 이러한 적조 생물의 증식과 집적은 수중의 용존 산소를 고갈시켜 다른 생물의 생존을 저해하며(Hallegraeff, 1993), 규조류와 더불어 적조원인의 주된 그룹을 형성하는 와편모류의 일부는 독성을 함유하고 있어, 해양 먹이망을 교란시키고, 어패류를 독화 시키는 등의 생태계 균형 붕괴의 원인이 된다. 또한 이러한 독성을 함유한 유해 미소생물로 인해 독화된 패류를 사람이 섭취하였을 때, 사람의 건강까지도 위협을 주고 있기 때문에 사회‧ 경제적으로 심각한 문제가 되고 있다(ECOHAB, 1995; Anderson, 1997; Park et al. | |
