| Abstract: | At densities of 500–9 000 cells/ml, the planktonic alga Chrysochromulina breviturrita Nich. produced obnoxious lake-wide odours in five lakes between 1978 and 1980. In one case, CuSO4 was used to kill the organism and control the odour, but in the other four lakes, the species persisted for 4–6 weeks before populations declined and odours disappeared. This is the first recorded instance of odour production by any member of the Prymnesiophyceae. |
