| 摘 要： | 为获知牡蛎对有毒微小亚历山大藻(A. minutum)的滤食以及蓄积PSP毒素的规律性，本实验采用细胞毒性为93.42±2.55×10-6 MU/cell的A. minutum藻投喂牡蛎，以无毒扁藻投喂作对照，首先研究了0.5-3.0×103 cells/mL6个不同浓度的毒藻对牡蛎滤食的影响，然后投喂浓度为1.5×103 cells/mL的毒藻，分别研究15 h短期蓄积和5天长期蓄积对牡蛎体内毒素的影响及规律。结果表明，在0.5~1.5×103 cells/mL毒藻浓度范围内牡蛎清滤率较高，超过1.5×103 cells/mL时牡蛎清滤率显著下降(P<0.01)，由此确定后期投喂毒藻的浓度“阀值”为1.5×103 cells/mL；短期蓄积实验牡蛎在0~6 h内将有毒藻滤食尽，其体内PSP毒素在6~12 h间达到最大值149.6±10.5 MU/100 g，随后开始下降。长期蓄积实验过程中，牡蛎的清滤率没有发生显著变化(P>0.01)，在蓄积实验的第2天牡蛎体内PSP毒素水平超过国家限量标准(400 MU/100g)，在5天实验结束时，牡蛎体内PSP毒素水平高达3069.2±178.2 MU/100 g，高于国家限量标准的7.7倍。实验结果作为PSP在牡蛎中蓄积及代谢的重要基础数据，为研究PSP的脱除及净化提供思路。
