Macrozoobenthos survey (benthic fauna)

perloOur deep knowledge of benthic invertebrates enables us to perform complete surveys of the aquatic environment.

The composition of the fauna and the biology of the species together with their ecology allows us to establish of a complete diagnostic of biotopes and biocenoses.

Such surveys allow to determine :


  • quality of an environment through biological index (IBGN/IBCH, IBEM, etc.)
  • the impact of works
  • influence of hydroelectrical activity
  • the ecological goals of regeneration
