通过使用天然藻类种群[优势种：中肋骨条藻，海链藻，裸藻属，异弯藻（以前称为Olisthodiscus luteus）和Eutreptiella sp.]采集自日本谷川港，那里偶尔发生赤潮。通过透析袋培养技术，具体评估了宏量和微量营养盐对不同种类藻类生长的影响。两种类型的反应，养分清楚地观察到;宏观和微观养分依赖。前者包括S.中肋骨条藻、海链藻（Thalassiosira sp.）和真盾藻（Eutreptiella sp.）异弯藻属是在后者组，这是由微量营养素刺激。Gymnastinium sp.为中间型。本文结合目前的养殖试验和现场观测结果，讨论了在港内试验期间形成的一次赤潮现象。
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.
