Potential toxicity of the freshwater Chrysochromulina species C. parva (Prymnesiophyceae)

A mass development of Chrysochromulina parva Lackey — 614 000 cells per ml, associated with fish mortality, is reported from a small Danish lake. None of the analyses performed showed any reason for the fish kill. Even oxygen conditions were favourable. Thus toxins from the Chrysochromulina might be responsible for the fish kill. If true, this would be the first record of toxicity in a freshwater Chrysochromulina.
