AVALIAÇÃO QUALITATIVA DE COMUNIDADES FITOPLANCTÔNICAS EM VIVEIROS DE PESQUE-PAGUE E SUA RELAÇÃO COM A SAÚDE PÚBLICA EM INHUMAS-GO, BRASIL

Abstract

The Fish-pay establishments represent a type of aquaculture that has become common in many regions of Brazil. Some of these establishments offer their fish in their restaurants while providing sport fishing and therefore should have their nurseries growing properly treated. These water bodies deserve special attention since improper handling can lead to eutrophication processes and the consequent multiplication of harmful algae to fish and also to those the consumers. In the city of Inhumas - Goiás - Brazil and surroundings there are many Fish-pay establishments, in farms and in urban perimeter of the city. Accordingly, the purpose of this study was to evaluate qualitatively the composition of phytoplankton in four of these establishments. The microscopic analysis revealed 41 different genera of microalgae, of which 15 belong to the Cyanobacteria, thus indicating that the studied environments lies in proper sanitation to shelter human activities.
