Abstract
Three harmful algal bloom species with similar morphology, Cochlodinium polykrikoides, Gyodinium impudicum and Gymodinium catenatum have damaged to aquatic animals or human health by either making massive blooms or intoxication of shellfishes in a food chain. Eco-physiological and hydrodynamic studies on the harmful algae offer useful informations in the understanding their bloom mechanism by giving promising data for the prediction and modelling of harmful algal blooms event. Thus, we studied the abundance of these species in the coastal area of South Sea of Korea and their effects of temperature, salinity, irradiance and nutrient on the growth for the isolates. The timing for initial appearance of the three species around the coastal area of Namhaedo, Narodo and Wando was between Bate July and late August in 1999 when water temperature ranged from
적조생물 Cochlodinium polykrikoides, Gyrodinium impudicum, Gymnodinium catenatum은 독성을 지니거나, 적조를 일으킴으로써 수산피해 및 보건위생상의 문제를 야기시키는 종이다. 이 종들의 적조발생 환경과 기작을 이해하기 위해서는 종별 생태생리 (eco-physiology) 특성 등을 파악할 필요가 있다. 본 실험에서는 한국 남해안 연안에서 이들 3종의 출현상황과 성장특성을 파악하기 위해 이 해역에서 분리한 종을 대상으로 온도, 염분, 조도 및 영양염류에 따른 성장도를 조사하였다. 1999년도 남해안 남해도, 나로도, 완도 연안에서 이들 3종의 최초출현시기는 수온이
