Conteúdo: | The Enseada do Brito is located in a sheltered cove, with rivers flowing into the region and malacoculture as their main source of income. This activity, as well as other aquaculture activities, enjoy the natural resources and causes changes in the environment. Thus, this study aimed to investigate a possible impact of shellfish farming on water quality in the region using the Coastal Environmental Quality Index (ICAC), based on the concentration of ammonia, nitrate, nitrite, ortophosphate and silicate. We selected five sampling stations in the cove called EB1, EB2, EB3, EB4 and EB5, divided into areas with or without influence of the molluscs cultivation and rivers. During the period August-October 2010, the parameters were monitored salinity (psu), transparency (cm), temperature (ºC) and pH. In october, water samples were collected at five stations in the cove for nutrient analysis, weighting, with the results, the values of the ICAC. During the suty period, the physical and chemical parameters remained constants and no difference was detected (p>0.05) between stations. ANOVA found no significant difference of the nutrients (p>0.05) of the ICAC and between stations (p=0.88). The results indicate that during the study of bivalve cultivation did not affect the water quality of the bay.
