Abstract
    Assessing the quality of a marine environment subjected to numerous discharges or substances from human activities and fixing regulations to authorise discharges at sea require bio-monitoring tools. Part of the series on "Méthodes d'analyse en milieu marin" (analytical methods in the marine environment), this fascicule describes a test protocol using embryo-larval development in bivalves as a tool to assess the potential toxicity of a substance or an aqueous medium. The acute toxicity bio-assay (24 h for cupped oysters and 48 h for mussels) can be applied at salinities ranging from 20 to 35 and make it possible to determine the concentrations inducing abnormal embryo-larval development. This bioassay will be useful for both environmental managers and researchers involved in marine environment bio-monitoring.
