摘要

1/1 abstract "Improvements introduced in closed autotrophic system for polyculture of fish, shrimp and algae through the cultivation of microalgae". it is an autotrophic system (10) for the cultivation of fish, shrimp and algae; said autotrophic system (10) uses as a food source the biomass (bm) obtained from the microalgae (mg) 'spirulina platensis', also obtained by the polyculture of fish, shrimp and algae; This autotrophic system (10) proposes the reuse of effluent (efi) from aquaculture of fish and / or shrimp whose treatment is performed using the microalga (mg) 'spirulina platensis; said autotrophic system (10) may be comprised of interconnected reservoirs (20) provided with treated effluent feed pipe (ti) and drainage pipe (t2); effluent treatment (efi) is carried out in a tank (30) provided with a submerged pump (40) for the movement of water; Fish / shrimp cultivation through the biomass obtained by the microalgae (mg) 'spirulina platensis' configures the autotrophic system (10).
