タイ湾より分離培養した Alexandrium cohorticula の給餌によるミドリイガイ Perna viridis の毒化

抄録

Twelve clones of Alexandrium cohorticula were newly isolated from the Gulf of Thailand and made cultured. All the clones were found to be toxic. However, the toxicity levels per cell were different from clone to clone even when cultured under the same conditions. The green mussel Perna viridis which were fed on the cultured cells of A. cohorticula accumulated about 50% of the toxin contained in the supplied cells, showing that A. cohorticula may cause bivalve toxicity, when it blooms in the environment.
