Resumo: | The current study was aimed at investigating the use of different fertilizers - dicalcium phosphate, biosolid and quail feces - as a strategy for water fertilization in Daphnia sp production. It was used twenty-four 100-L tanks of asbestos cement distributed in a completely randomized split-plot design with six replicates, with plots in the three kinds of fertilizers (biosolid, dicalcium phosphate, and quail feces) and a control without fertilization (WF) and subplots at the times of assessment (days 8 and 13). It was assessed the biomass production of Daphnia sp. and the following water quality parameters: chlorophyll a, electrical conductivity, pH, dissolved oxygen, temperature, ammonia and organic nitrogen, total phosphorus and total hardness. There was a significant correlation between the values of chlorophyll a and biomass weight of Daphnia sp, which indicates interactions between phytoplankton and zooplankton communities. The maximum weight of Daphnia sp. biomass is found in tanks fertilized with quail feces (35.98 g), followed by the biosolid (16.80 g), control without fertilization (6.75 g) and dicalcium phosphate (5.24 g).
