Conteúdo: 	This experiment was run at Fish Culture Sector of Escola Agrotécnica Federal de Concórdia - EAFC, located at Concórdia, Santa Catarina West region. Three systems of fish polyculture were compared: i) fish polyculture with swine manure input (45 pigs/ha); ii) polyculture with swine manure input (60 pigs/ha); and iii) polyculture with formula feed input. Environmental assesment of the tested systems was done comparing pond water quality with environmental regulations in Brazil. Critical volume method and critical volume relation with biomass production were used as adicional tools for comparing studied systems. Phosfate was by far de most critical parameter of culture systems regarding environmental impact. Increasing manure input to the ponds resulted in increased environmental impact regarding fecal coliforms. Considering total biomass produced by
systems i), ii) and iii), critical volume relation to biomass indicated a better "cost/benefit" rate for swine manure input systems. These systems also showed a smaller acumulation of organic matter on pond bottom when compared to the formula feed system.
