“…However, nutrient availability was higher in the flow-through culture, resulting in greater total nutrient uptake and thereby more growth, as indicated by the greater final biomass in these cultures. The removal efficiency for total phosphorus 36% -50% in the flow-through system which was comparable with other experiments in which Kappaphycus alvarezii (27%) and Ulva reticulate (33%) have been used as biofilters in fish effluents [28].…”

Aquaculture industry is often generating waste that negatively impact to the environment. These wastes are rich in nutrients. Seaweed can utilize these waste nutrients. This experiment was conducted in a flow-through system (FTS) and a recirculation system (RS) in land-based integrated multi-trophic aquaculture module using seaweed Kappaphycus alvarezii as one of the components. The aim was to access the efficiency of the removal of nutrients in the integrated culture. Kappaphycus alvarezii was stocked at the density of 1 kg/tank in the rectangular plastic tank with 500 L of seawater. The waste generated from integrated multi-trophic aquaculture tanks was directed towards K. alvarezii culture tank. Water samples from inlet, outlet and inside of the culture tanks were drawn to determine the nutrients, namely, total nitrogen (mg/L) and total phosphorus (mg/L). Total nitrogen and total phosphorus in the seaweed sample and from the sediment of culture tanks were also analyzed. The total nitrogen amounting to 59.5% and 61.6% nitrogen was taken up by K. alvarezii in FTS and RS culture tank, respectively. The phosphorus showed the highest deposition of 61.1% and 31.6% in the sediment of in FTS and RS culture tanks respectively, whereas only 5.5% and 3.4% of phosphorus were taken up by K. alvarezii from FTS and RS culture tanks, respectively. The percentage of nitrogen remained in water was comparatively higher by 14.2% and 27.5% than phosphorus by 8.3% and 23.0% in water of both FTS and RS culture tanks, respectively. These results indicated that this species seaweed is efficient in the removal of nitrogen from both FTS and RS culture tank.

“…Many species of macroalgae are effective in removing nutrients from water and show a high potential for IMTA in RAS (HAYASHI et al, 2008;NEORI, 2008;MARINHO et al, 2013). Several studies have proven the efficiency of macroalgae in retaining nitrogen compounds derived from IMTA (NEORI et al, 2003;NEORI, 2008;COPERTINO et al, 2009;CRUZ-SUÁREZ et al, 2010;MARINHO et al, 2013).…”

Seaweeds have many uses in industry and agriculture and many species have potential for integrated multi-trophic aquaculture (IMTA), since they are efficient in removing nutrients from water. The efficiency of Ulva flexuosa, U. fasciata and Gracilaria birdiae in removing nutrients from enriched water and their productive performance in outdoor tanks were quantified. These seaweeds (50 g; n = 5) were grown in tanks containing 50 L of eutrophic seawater, with a salinity of 30, a temperature of 28.5 ± 2.8 °C, an irradiance of 547 ± 458 μmol photons m -2 s -1 and aeration. The nutrients levels were recorded daily and when total nitrogen removal was detected, the biomass was measured. After five days of cultivation, more than 98% of NH3 (H = 1.1; P = 0.56) and NO3 -(H = 2.7; P = 0.25) and 62.1% of PO4 3-(H = 0.0; P = 0.90) had been removed from the tanks. However, the mean daily growth rate (4.5 ± 2.5% day -1 ) and productivity (3.5 ± 1.9 g m -2 day -1 ) of U. fasciata and G. birdiae were higher than U. flexuosa (-13.6 ± 7.7% day -1 ; -6.24 ± 2.8 g m -2 day -1 ; P<0.01), demonstrating that microalga contamination by this species promoted high removal efficiency in the tanks, but a low productive performance. Based on these results, U. fasciata and G. birdiae show a greater potential for use in IMTA to improve water quality and produce biomass.Keywords: Gracilaria birdiae; productivity; daily growth rate; nutrient removal; Ulva fasciata; Ulva flexuosa EFICIÊNCIA BIOFILTRADORA E DESEMPENHO PRODUTIVO DE MACROALGAS COMPOTENCIAL PARA AQUICULTURA MULTI-TRÓFICA INTEGRADA (AMTI) RESUMOAs macroalgas são utilizadas em diversos setores industriais e agrícolas. Além disso, muitas espécies apresentam potencial para aquicultura multitrófica integrada (AMTI), pois são eficientes na remoção de nutrientes da água. A eficiência biofiltradora e desempenho produtivo das macroalgas Ulva flexuosa, U. fasciata e Gracilaria birdiae e foram quantificados em tanques outdoor. As algas (50 g; n = 5) foram cultivadas em tanques de 50 L, com água eutrofizada, salinidade 30 e temperatura média 28,3 °C. Os nutrientes foram monitorados diariamente e a biomassa foi mensurada assim que detectada a extinção do nitrogênio. Após cinco dias de cultivo, mais de 98% de NH3 (H = 1,1; P = 0,56) e de NO3 -(H = 2,7; P = 0,25) e 62,1% de PO4 3-(H = 0,0; P = 0,9) foram removidos dos tanques. Contudo, a taxa de crescimento (% dia -1 ) e a produtividade (g m -2 dia -1 ) de U. fasciata e de G. birdiae (4,5 ± 2,5% dia -1 ; 3,5 ± 1,9 g m -2 dia -1 ) foram superiores às de U. flexuosa (13,6 ± 7,7% dia -1 ; 6,2 ± 2,8; P<0,01), cuja contaminação por microalgas contribuiu para elevada eficiência de retirada nos tanques desta espécie, mas baixo desempenho produtivo. Desta forma, U. fasciata e G. birdiae foram indicadas para AMTI tanto para a manutenção da qualidade da água quanto para aproveitamento de biomassa.

“…in the water column. Several studies have shown the suitability of submersed macroalgae for treating the mariculture wastewaters MartinezAragón et al, 2002;Neori et al, 2004;Hayashi et al, 2008;Marinho-Soriano et al, 2009). Besides assimilating nutrients, through photosynthesis, macroalgae can elevate oxygen and pH levels (Porrello et al, 2003;Msuya et al, 2006) and propitiate processes of mineralization and nitrification.…”
