“-”means no further experiments were conducted because of the weak algicidal activities in preliminary tests.

Except for some crude extracts that promoted algal growth,most of the crude extracts obtained showed varied algicidal activities(Table 1).None of the H.akashiwo cells could survive treatment with50μg/mL crude extracts from strains cf-8,cf-25-1,cf-32-1,dl-29,dl-34,pt-20,qd-20,qd-21,and yt-17.Similarly,treatment with 2.5μg/mL crude extracts from strains cf-32-2,dl-4,lyg-8,pt-20,qd-20,qd-21,and yt-5 resulted in the death of all C.marina cells.Furthermore,400μg/mL crude extracts from strains cf-36-1,cf-25-1,lyg-11,cf-41-1,yt-21,cf-44-1,lyg-8,and hd-5 showed strong antialgal activities against A.tamarense with IR values higher than 70%,while200μg/mL crude extracts from strains yt-11,cf-32-1,cf-28-2,dl-29,na-5,pt-1,cf-42,yt-8,and yt-13presented strong antialgal activities against P.donghaiense with IR values higher than 50%.
