Abstract: The effluents from fish farming can increase the quantity of suspended solids and promote the enrichment of nitrogen and phosphorus in aquatic ecosystems. In this context, the aim of this work was to evaluate the efficiency of three species of floating aquatic macrophytes (Eichhornia crassipes, Pistia stratiotes and Salvinia molesta) to treat effluents from Nile tilapia culture ponds. The effluent originated from a 1,000-m 2 pond stocked with 2,000 male Nile tilapia Oreochromis niloticus. The treatment systems… Show more

“…In constructed wetlands, these parameters are removed by macrophytes, microphytes and other microbial uptake where, the inorganic nutrients are converted to organic biomass and stored as tissues [9] [10] [11] [45]. Some previous authors have reported higher significant removals of phosphorus species than nitrogen species in constructed wetlands [17] [54] [55]. No significant differences were noticed in the removal of the two species in this work.…”

“…According to Wang and Lu (2015), systems using tilapia in polyculture increase feed efficiency, improving the water quality, the total yield of production and profits. Besides, it is necessary to use wastewater treatment systems using constructed wetlands (Henry-Silva and Camargo, 2006), allowing the reuse of water by the system and/or the water release in appropriate conditions to the current legislation.…”

“…An important aspect for increase the nutrient removal efficiency in wetlands is the periodic removal of old macrophytes since these plants have a limited capacity to store nutrients and organic matter [6]. When support capacity is reached, leads to a low production or biomass loss and nutrients stored return to wastewater [31].…”

“…Due to the need for wastewater treatment from aquaculture activities, the use of constructed wetlands has been increasingly studied in recent years in Brazil [6] [7] [8] [9] in order to minimize their impacts on the environment. Constructed wetlands have aquatic plants that remove nutrients from the water using them for their own growth.…”
