Abstract

We investigated cause of non-outbreak of Cochlodinium polykrikoides blooms in the western coast of Jaran Bay during summer, 2013, based on the species competition among C. polykrikoides and Skeletonema sp. using a mathematical model. As a result of the model simulation where the nutrient conditions in Jaran Bay was applied during summer, the cell density of Skeletonema sp. was higher than that of C. polykrikoides. In the sensitivity analyses by doubling and halving the parameters, any parameter had little effect on the cell density of C. polykrikoides. The cell density of Skeletonema sp. was significantly affected by changes in the parameter values. These results indicated that the growth of C. polykrikoides could be unaffected by rapidly changing environments. However, the growth of Skeletonema sp. may have been promoted by the changing nutrient supply of coast environments. Therefore, C. polykrikoides might have been suppressed by diatom blooms, such as Skeletonema sp., in changing nutrient supply condition of Jaran Bay.

수치모델을 활용한 Cochlodinium polykrikoides와 Skeletonema sp.의 영양염에 대한 종간경쟁을 바탕으로 2013년 하계 자란만에서 C. polykrikoides의 적조 미발생 원인을 고찰하였다. 2013년 하계 자란만의 영양염 조건을 모델에 적용시킨 결과, 실제 현장과 유사하게 Skeletonema sp.의 세포밀도는 C. polykrikoides보다 높았다. 또한 다양한 변수에 대한 민감도 분석에서, C. polykrikoides는 어떠한 변수의 변화에도 일정한 세포밀도를 보였으며, Skeletonema sp.의 세포밀도는 영양염 농도의 증 감에 민감하게 반응하였다. 이러한 결과를 통해 C. polykrikoides는 급격한 환경변화에도 영향을 받지 않고 생장을 유지할 수 있을 것이다. 하지만 영양염 공급이 변화하는 연안환경에서는 Skeletonema sp.의 생장이 촉진될 수 있을 것이다. 따라서 외부로부터 영양염의 공급이 크게 변화하는 자란만에서 Skeletonema sp.와 같은 규조류의 번무에 따라서 C. polykrikoides의 출현이 억제된 것으로 보인다.
