The aim of this study was to evaluate the use of effluent of tilapia culture in biofloc systems as culture medium for production of Scenedesmus sp. The effluent was separated into solid waste (RS) and liquid waste (RL); and with both culture media were prepared. 3 bioassays were performed: bioassay I, dilution in sterile water; bioassay II, replacement of a commercial culture medium; and bioassay III, replacement of a commercial culture medium and enrichment with metals and vitamins. Treatments for RL media consisted of 3 levels of inclusion: T1 (50% RL), T2 (75% RL) and T3 (100% RL); while for RS media were four T1 (25% RS), T2 (50% RS), T3 (75% RS) and T4 (RS 100%); using as a control f/2 medium Guillard (f/2). The growth rate (μ) and doubling time (TD) showed significant differences (p <0.05) between the RL media and control f/2 in all biossays, noting that the largest μ and lower TD were present in the RL medium in thebioassay III. While, in RS media only were observed differences during the bioassay I (p<0.05)between control f/2 and treatments T1 and T2; in bioassays II and III, no differences (p> 0.05)were reported. The maximum cell density (DCM) in RS media showed differences (p<0.05)between treatment T4 and f/2 control in all bioassays; while for RL media; only weew fund differences during the bioassay II(p <0.05)between T1 and control f/2. It can be concluded that only the RL media from biofloc effluent can be used for the production of microalgae Scenedesmus sp.
