由甲藻属Dinophysis产生的腹泻性贝类毒素是全世界贝类产业的一个主要问题。该属的不同物种与冈田酸毒素的不同类似物的产生有关。为了评估苏格兰西海岸重要的贝类捕获区内藻类物种和毒素的时空变异性，我们分析了1996年至2017年在两个不同地点收集的数据：伊维湖和克莱德海。还进行了季节性研究，2001年和2002年在伊夫湖，2015年在克莱德河。在研究的每一年中，在整个生长季都有尖柄裸藻的存在，两个地点的开花通常都在5月至9月之间。尖头金线虫的出现是每年零星出现的，当出现时，在夏末和秋季最为丰富。克莱德在2015年的实地研究表明，温度锋在尖吻金藻水华形成中的重要性。在调控监测期间，常见贻贝(Mytilus Edulis)的毒素谱发生了明显的变化，冈田酸(OA)和甲藻毒素-1(DTX1)的比例下降，甲藻毒素-2(DTX2)的含量上升。对藻类的常规计数可对贝类可能受到DTX2污染提供早期预警，从而确定选择最合适的试剂盒进行有效的最终产品测试。
Diarrhetic shellfish toxins produced by the dinoflagellate genus Dinophysis are a major problem for the shellfish industry worldwide. Separate species of the genus have been associated with the production of different analogues of the okadaic acid group of toxins. To evaluate the spatial and temporal variability of Dinophysis species and toxins in the important shellfish-harvesting region of the Scottish west coast, we analysed data collected from 1996 to 2017 in two contrasting locations: Loch Ewe and the Clyde Sea. Seasonal studies were also undertaken, in Loch Ewe in both 2001 and 2002, and in the Clyde in 2015. Dinophysis acuminata was present throughout the growing season during every year of the study, with blooms typically occurring between May and September at both locations. The appearance of D. acuta was interannually sporadic and, when present, was most abundant in the late summer and autumn. The Clyde field study in 2015 indicated the importance of a temperature front in the formation of a D. acuta bloom. A shift in toxin profiles of common mussels (Mytilus edulis) tested during regulatory monitoring was evident, with a proportional decrease in okadaic acid (OA) and dinophysistoxin-1 (DTX1) and an increase in dinophysistoxin-2 (DTX2) occurring when D. acuta became dominant. Routine enumeration of Dinophysis to species level could provide early warning of potential contamination of shellfish with DTX2 and thus determine the choice of the most suitable kit for effective end-product testing.
