Colimetria de ambientes aquáticos com cultivo de jaú, Zungaro jahu em Conceição das Alagoas/Minas Gerais

Resumo (EN)

Objective – To evaluate quantitatively the variation of coliforms (fecal and total) in water of a fish farm at the Triângulo Mineiro associated with the cultivation of Jau (Zungaro Jahu). Methods – The water samples were collected at five points at the fish farm for a period of six months. After collection, the samples were sent to the laboratory of ecology “Nico Nieser” at the Federal University of Triângulo Mineiro, Uberaba - MG and plated in specific culture media for growth of Gram-negative bacteria. The species identification was made by specific biochemical tests. Results – In the present study we isolated eight colony forming units (CFU) of fecal coliforms, and 53 CFU of total coliform. Conclusion – The results found in our study showed that this enviroment is compared with Class II of the CONAMA resolution 357 and characterize this environment as favorable for fish farming.
