Abstract Three semi-continuous culture experiments were conducted by using natural algal populations [dominants: Skeletonema costatum, Thalassiosira sp., Gymnodinium sp., Heterosigma sp. (formerly called Olisthodiscus luteus) and Eutreptiella sp.] collected from Tanigawa Harbor, Japan, where red-tides occurred occasionally. The effects of macro- and micro-nutrients onto the growth of different species of algae were specifically evaluated by a dialysis bag culture technique. Two types of responses for nutrients were clearly observed; macro- and micro-nutrient dependency. The former group includes S. costatum, Thalassiosira sp. and Eutreptiella sp. which mainly stimulated their growth by macro-nutrients. Heterosigma sp. was in the latter group which was stimulated by micronutrients. Gymnodinium sp. showed an intermediate type. A red-tide of Heterosigma sp. formed during the experiment in the harbor and is discussed with the results of the present culture experiments and some field observations.
