WebThe dinoflagellate genus Alexandrium comprises most of the toxic bloom-forming species producing paralytic shellfish toxins (PSTs) in the sea. However, Colin and Dam (Colin and Dam, 2003) found that the depression of feeding rate of copepods exposed to high concentration of Alexandrium fundyense could be alleviated if copepods were exposed to low concentrations of A. fundyense before the test, which indicates that the negative response of ephyrae exposed to high concentrations of A. catenella might be alleviated if ephyrae were acclimated to low concentration in the coastal waters.
