| Microphytobenthos activity in coastal waters has been studied at two shellfish fanning sites: an oyster farm in Thau lagoon and a mussel farm in Carteau bay (NW Mediterranean coast). In both cases, shellfish are cultivated on ropes hanging from rigid structures (tables) in shallow waters (- 5 m). An ''under table'' station and an ''outside table'' (reference) station were chosen at each site. Oxygen and ammonia fluxes at the water-sediment interface were measured in dark and transparent benthic chambers. Chlorophyll a concentrations were two- to threefold higher in ''under table'' sediments than outside (260 mg Chl a m(-2) under the oyster table, 436 mg Chl a m(-2) under the mussel table in winter). Net oxygen fluxes were negative at all stations, except... |
