Characterization and Classification of Different Aquaculture Tunisian Water using an Electronic Tongue

In this report we present a comparative study realized on different aquaculture water samples collected from several fish farms in Tunisia. For each water sample, significant physiochemical parameters such as conductivity, pH, NH4 + , Na + , Ca 2+ , F and NO3 were determined using a potentiometric multi-sensor system named "electronic tongue". Experimental analysis data were standardized and subjected to principal components analysis (PCA) in order to classify, to control and to maintain the quality of water needed for aquaculture purposes. In particular, our study has been profoundly interested to Hergla farm comparing the quality of its aquaculture reject water to other wastewater resources. It is meant by this procedure to elucidate the impacts of aquaculture on its surrounding environment. This leads to a better opportunity to give the objective elements used for the comparative judgement of the polluted aquaculture.
