In this paper, a research project is presented. This project goals are mainly to identify the environmental factors (temperature, nutrients, zooplankton,\342\200\246) driving the development of a toxic cyanobacterium species (P. agardhii) and the variations of the toxic and non-toxic clones, in a retention pond. The physico-chemical context, the phytoplankton dynamics and the toxin production have been monitored by a fortnightly field survey, whose preliminary results are presented.
