The effect of Maerl extraction on Benthic Communities in the Glénan Archipelago.

The DORIS programme (Data from Observations for the Recognition and Identification of Underwater Fauna and Flora) relies primarily on the network of divers from the Biology and Underwater Environment Commissions coordinated by the CNEBS of the FFESSM (French Federation of Underwater Studies and Sports).

Upon building a new waste pool for waste from oyster farming, a zostera noltii seagrass meadow was destroyed by sediment deposits. This site is located in the Arcachon basin and has been monitored since 2005 in order to evaluate the impact this of this work and the recolonisation of the site by benthic macrofauna.
