Sanidade de ostras (Crassostrea rhizophorae) cultivadas na Reserva Extrativista Marinha Baía do Iguape, Bahia

Abstract

The monitoring and quality control of the aquatic environment and the evaluation of the health of oysters produced are fundamental to a safe and sustainable production of these bivalves. This study aimed to describe the microbiological profile, parasitological and toxicological and histopathological changes of Crassostrea rhizophora e produced in the Marine Extractive Reserve Bay Iguape-BA. We collected 600 species of oyster and 120 samples of water from November 2013 to November 2015. The results showed that the oysters were satisfactory sanitary quality according to Brazilian and international laws. In the determination of toxic metals in the specimens there was contamination of 6.67% for lead and 13.33% for cadmium being associated with this rainfall peaks. Were identified bacteria, protozoa and metazoan, but no notifiable and that showed no significant damage to bivalves. It is concluded that the oysters grown in RESEX Iguape Bay have good general health and microbiological quality and satisfactory parasite. In addition, histopathological changes observed no significant dimensions for the characterization of the lesion confirming the good health of oysters. It emphasizes the need management strategies, monitoring and quality control continuous, to reduce microbiological, parasitological and chemical contamination, supervision to prevent new pollution sources, and the inclusion of maximum limits for toxic metals and parasites to establish mandatory reporting on health programs mollusc order to maintain the safety of oysters for consumption, strengthening the safe and sustainable production of native oysters and ensure food and nutrition security of consumer.
