塔玛亚历山大藻是一种能产生麻痹性贝毒的有毒甲藻,它所引发的赤潮在世界各地多有发生，对海水养殖业和人们的生命安全造成很大的威胁［３］。有毒赤潮发生时,贝类起一种媒介的作用,可将有毒藻产生的毒素累积在体内,沿食物链转移给高营养级生物和人,使之中毒［４］。已有研究表 Alexandria tamarense, a kind of noxious dinoflagellate that produces paralytic shellfish poison, causes many kinds of red tides, which are all over the world, threatening the life safety of mariculture and people [3]. When poisonous red tide occurs, shellfish act as a medium that can accumulate the toxins produced by toxic algae in the body and transfer it to high trophic levels and people along the food chain for poisoning [4].
