Abstract

The infestation of polychaetes Polydora in oyster C. gigas within cultivation was accompanied by monthly samples whereas the physical and chemical parameters of seawater were monitored weekly. The total area occupied by bubbles and tubes in the inner surface of the valve was determined, indicating the possible damage to the main physiological characteristics of oysters. It was observed prevalence of annelid Polydora sp. (Polychaeta: Spionidae) in all samples each month, reaching 100% in the period of cooler waters. The histological analysis showed that the tissues and organs were intact, occurring the formation of gametes. In oysters severely infested, it was possible to observe intense fibrosis in the mantle, showing repair of the tissue.
