Análise situacional da qualidade de água nas zonas de uma instalação piscícola no Ceará - Brasil

Abstract

The water quality indexes have often been studied, taking advantage of the use of your information as management tools for decision making regarding water resources. This study aimed to assess the variation in water quality indexes (WQI) and trophic state (mTSI) in the areas of influence of an installation to family pisciculture in the weir Pereira de Miranda in Pentecost, Ceará. Data were collected to analysis physicochemical and bacteriological for sampling at six sites in the dry and rainy season). Through these variables the WQI and STI were established for each site in the two collection periods. The water results were classified as good quality in almost all the points studied. This suggests that fish farming activity practiced in the were are not compromising the multiple uses of the reservoir water. Because they have the ease of communication with the non-technical public through their results, such indices can be replicated in the regions with similar and increasingly improved in features studies.
