与软骨藻酸(DA)的产生有关的硅藻属伪菱形藻(Peragallo)在苏格兰水域丰富。软骨藻酸是一种可导致遗忘性贝类中毒的毒素。一项为期两年的研究考察了两个地点的蓝贻贝(Mytilus Edulis)和一个地点的扇贝(Pecten Max)的DA浓度与水柱中的假菱形藻细胞之间的关系。两种鱼对DA的吸收和净化速率差异很大，每周累积净化7mgg(-1)(现在用mg kg(-1)表示)。反之，DA从68微克g(-1)(现在的mg kg(-1))的浓度提纯到性腺组织用了12周。
The diatom genus Pseudo-nitzschia (Peragallo) associated with the production of domoic acid (DA), the toxin reposnsible for amnesic shellfish poisoning, is abundant in Scottish waters. A two year study examined the relationship between Pseudo-nitzschia cells in the water column and DA concentration in blue mussels (Mytilus edulis) at two sites, and king scallops (Pecten maximus) at one site. The rate of DA uptake and depuration differed greatly between the two species with M. edulis whole tissue accumulating and depurating 7 mu g g(-1) (now expressed as mg kg(-1)) per week. In contrast, it took 12 weeks for DA to depurate from P. maximus gonad tissue from a concentration of 68 mu g g(-1) (now mg kg(-1)) to
