Etude ecophysiologique de quelques mollusques bivalves

Using an experimental flowing system, the filtration rate of Mytilus galloprovincialis, Ostrea edulis, Ruditapes decussatus and Ruditapes aureus has been measured by an indirect technique under Mediterranean thermal conditions in coastal open sea. The oxygen consumption and excretion rate of ammonia have been estimated and influence of temperature and salinity tested for M. galloprovincialis . The results are discussed and compared to literature data.
