Resumo: | Summer mortalities in the Pacific oyster in the Bay of Arcachon were analysed during four years (1981 to 1984). Mortalities occur mostly among one year old oyster and affect the whole bay, with different prevalence. The phenomenon occurs at certain times during the summer spawning period and is associated with high temperatures. A thinning of the digestive tubule epithelium is observed, but there is no evidence of infectious disease. The failure to find a causative agent, pollution or pathogen, tends to strengthen a physiological disorder hypothesis, related to environmental conditions. The influence of external (temperature, available food) and internai factors (length, maturation, spawning) on this phenomenon is discussed. A comparaison is drawn with mortalities recorded in Japan and the United-States. [NOT CONTROLLED OCR]
