The present study was conducted at Saco da Fazenda Estuary, state of Santa Catarina, Brazil. The relationship between the abiotic variables and the diversity of birds at that site was evaluated over a period of ten months (July 2006-April 2007). The diversity and equitability indices showed similar fluctuations over the study period, with significant differences between sampling months (F11-132=17,061, p<0.001) and (F11-132= 7,789, p<0.001). These values were affected by the lower average scores between October and December, in contrast with the higher ones recorded in August, September and July, probably influenced by the dominance of P. brasilianus and L. dominicanus. The diversity and evenness indices presented similar oscillations over the study months, with significant differences between the sampling months (F11-132=17,061; p<0.001) and (F11-132=7,789; p<0.001) respectively. The Spearman's correlation analysis revealed a significant negative correlation (r = - 0.317, n= 135, p<0.05) between diversity of the aquatic birds and air temperature, but no correlation with wind speed or intensity or height of the tides. In relation to winds, the highest numbers of individuals were recorded in the easterly and east-northeasterly directions and the smallest for the southeasterly winds.

The consumption of marine organisms, especially bivalve molluscs, might affect the human health, once that they concentrate in their tissues, suspended particles, including pathogenic microorganisms. Cananéia region is the largest oyster producer in the state of São Paulo, and in 1999 was founded the Cooperostra (Cooperative), which promotes the oysters depuration process in sterile tanks, leading to reduce and/or eliminate retained substances in their tissues. This study aims (i) evaluate the water quality in the adjacencies of the natural oysters’ beds and during the steps of the depuration process, through the determination of Escherichia coli, total coliforms and thermotolerant coliforms, and (ii)evaluate the contamination of Crassostrea sp by Salmonella sp., total coliforms, thermotolerant coliforms and Staphylococcus coagulase positive, in samples collected at Cooperostra and in natural oysters’ beds, assessing the contamination level of the organisms and the efficiency of the depuration process. The results show a reduce of Salmonella sp and coliforms densities in the oysters’ tissues after the depuration process. However, Staphylococcus coagulase positive shown high levels, which may be indicative of handling contamination. The Salmonella sp results were in agreement with RDC n12. © 2016, Instytut Technologii Drewna. All Rights Reserved.
