BIO-LITTORAL is a start-up from the University of Nantes created in 2004, specializing in marine and estuarine environmental monitoring in the Atlantic and the English Channel. Thanks to its team of taxonomists (macroflora, macrobenthos and fisheries) and numerous tools of investigation adapted to each environment, Bio-Littoral is requested by State services (OFB, MNHN, IFREMER, DREAL) to participate in numerous research programs in order to validate protocols or disturbance indicators. Bio-Littoral completes its database on the functioning of the marine ecosystem through regulatory monitoring concerning the impact on benthic and fish populations and marine habitats of anthropogenic activities such as the extraction of marine aggregate, dredging and immersions at sea and more recently on Marin Wind Farm.
