Abstract
Algal growth potential (AGP) assay using Cochlodinium polykrikoides was conducted in Saryang Island coast where C. polykrikoides red tide occurred annually from July to October 1998. The effects of macro- and micro-nutrients on the growth of C. polykrikoides were specifically evaluated by the algal assay method. Two different types of growth response of C. polykikoides for the addition of nutrients were clearly obseued. For both before and after C. polykrikoides occurrence, the growth of C. polykikoides was significantly stimulated by the addition of either nitrate or ammonium of
우리나라 남해안에서 매년 유해 와편모조류인 Cochlodinium polykrikoides에 의한 적조가 발생하고 있는데, 본 연구에서는 남해안의 사량도 주변 해역을 대상으로 AGP 시험을 통하여 C. polykrikoides의 성장 제한영양염을 평가하였다. Macro- 및 micro-nutrients 첨가에 의한 적조 발생 단계별 C.polykrikoides의 성장은 두 가지의 서로 다른 반응으로 나타나 조류성장 제한영양염이 명확하게 확인되었다. 사량도 해역의 고정점에서 적조가 발생하기 전인 7월과 8월, 적조가 소멸한 후인 10월의 AGP 시험에서는 질산질소 (
