The boats cruising in the oyster growing areas are protected against biofouling by paints which release toxic compounds such as copper oxide and organotins into the water. After an estimation of the inputs of copper and organotins in the "Marennes-Oleron", Arcachon (Atlantic)    and Thau (Mediterranean Sea) areas, their influence on larval fixation is discussed, taking into account the tributyltin toxicity against D larvae of Crassostrea gigas. Laboratory experiments have demonstrated that tributyltin produces morphological abnormalities of the shell and increases tin levels in tissues, interfering with copper and zinc metabolism. The influence of yacht ports on oyster growth and shell morphology, has been demonstrated in the field. The use of...

Experiments in oyster-breeding areas where oyster Crassostrea gigas suffers from anomalies of calcification, show an obvious correlation between the importance of the malformation of shells and the vicinity of port areas where a great number of boats usually stay. Organotin compounds contained in antifouling paints, and more precisely Tributyltin fluoride (TBTF) induce, in experimental environment, similar anomalies to those observed in natural environment. The amounts of total tin in the tissues of oysters living in the vicinity of spots where organotin products are brought in, can reach high values, though they appear to decrease rapidly whereas the environmental contamination lessens. The authors suggest that results of organotin upon the mechanisms of...
