REPHY/REPHYTOX Observation and Monitoring Locations

Phytoplankton biomass and diversityInvertebrate abundance and distribution

REPHY is a national network covering the coast of the French mainland along with that of three of its overseas departments: Martinique, Guadeloupe and Reunion Island.

The aims are as follows:

  • to observe all phytoplankton species in the coastal waters and to monitor events such as coloured water, exceptional blooms, and the proliferation of species which are toxic or disruptive to marine fauna,

  • Particularly to monitor species producing toxins which are dangerous to shellfish consumers .

These objectives are complementary, as the regular monitoring of all phytoplankton species makes it possible to detect known toxic and invasive species, but also to detect potentially toxic species. It is the presence of these toxic species in the water which triggers the monitoring of toxins in shellfish. The mission of REPHY is to monitor shellfish in their natural environment (such as parks and deposits). For shellfish removed from marine environments (that is to say in shellfish logistics establishments or on markets prior to export), national monitoring and control plans are organised by the General Food Directive at the French Ministry of Agriculture. Analyses are performed by the accredited departmental veterinary laboratories as organised by the National Reference Laboratory from the French Food Safety Agency.
