摘　　要：通过对2005年4月至9月广东近岸海域贝类81个样品的腹泻性贝毒素进行小白鼠生物法检测,结果表明:(1)DSP毒素含量值≥0.05MU/g的有34个样品,其中翡翠贻贝和牡蛎所占的比例最大;同种贝类的腹泻性贝毒素存在一定的季节差异,秋季含量最高。(2)对其中腹泻性贝毒素含量值较高的8个样品进行胃含物海洋微藻种类的鉴定,结果是波纹巴非蛤、三棱骨螺和结蚶胃含物样品中含有产腹泻性贝毒的利玛原甲藻(Prorocentrum lima)和原甲藻(Prorocentrum sp.)。The diarrhetic shellfish poisoning（DSP）contents in 81 shellfishes of coastal water of Guangdong during April 2005 to September 2005 were tested with AOAC bioassay method. The results showed that： 1） There were 34 samples in which the DSP content was greater than or equal to 0.05 MU·g-1,and the proportion of Perna viridis and Oysters were higher than other species. The same kind of shellfishes accumulated different contents of DSP because of seasonal change, and the DSP contents of shellfishes were the highest in autumn; 2） Marine microalgae in the stomach contents of the top 8 samples with high values of DSP were identified, and the results showed that there are DSP toxic algae Prorocentrum lima and Prorocentrum sp. in three kinds of shellfish samples.
