“…The similarity of the Tambaqui physiological profile on all three treatments reflects a satisfactory rearing environment. Similar productive performances in pond systems were obtained by Kubitza et al [22] with Micropterus salmoides and Affonso et al, [9] with Tambaqui in pond culture and Good et al [23] with O. mykiss.…”

The effects of temperature and carbon dioxide (CO 2 ) changes on different haematological parameters and enzymes activities such as on LDH (Lactate de Hydrogenase), MDH (Malate de Hydrogenase) & GST (Glutathione-STransferase) were studied in the liver and skeletal muscles of Tambaqui fish (Collosoma macropomum, Cuvier, 1818) in the Laboratory of Ecophysiology and Molecular Evolution (LEEM) of the National Institute for Amazonian Research (INPA). The experimental procedures involved the exposure of fish to temperature rise from 28Cº to 32Cº and an increased in CO 2 concentration up to 10 times higher than the current levels for 24, 48, 72 and 96 hours. The levels of LDH, GST and MDH in both the tissues of Tambaqui (Muscles & Liver) showed a significant decreased at different along the different exposure periods. The levels of plasma glucose in blood decreased and the values of Hb, Ht, RBC, VCM, and HCM & CHCM showed increased after the exposure.

“…One of the principles of RAS is the use of filters that enhance the development of nitrifying bacteria responsible for the oxidation of ammonia to nitrate, although these metabolic wastes accumulate in the system and can harm the development and health of animals (DAVIDSON et al, 2009;GOOD et al, 2009). The nitrate that accumulates in RAS can cause chronic toxicity to fish, particularly in systems that operate with low water renewal (DAVIDSON et al, 2014).…”

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.

Abstract:The aim of the study was to analyze and assess the possibility of using a two-stage fi ltration system with ceramic membranes: a 3-tube module with 1.0 kDa cut-off (1 st stage) and a one-tube module with 0.45 kDa cut-off (2 nd stage) for treating effl uent water from a juvenile African catfi sh aquaculture. The study revealed that during the 1 st fi ltration stage of the effl uent water, the highest degrees of retention were obtained with respect to: suspended solids SS (rejection coeffi cient R I =100%), turbidity (R I =99.40%), total iron (R I =89.20%), BOD 5 (R I =76.0%), nitrite nitrogen (R I =62.30%), and COD Cr (R I =41.74%). The 2 nd fi ltration stage resulted in a lower reduction degree of the tested indicators in comparison to the 1 st fi ltration stage. At the 2 nd stage, the highest values of the rejection coeffi cient were noted in for the total iron content (R IV =100%), COD Cr (R IV =59.52%; R V =64.28%, R VI =63.49%) and turbidity (R IV and R V = 45.0%, R VI =50.0%). The obtained results indicate that ceramic membranes (with 1.0 and 0.45 kDa cut-offs) may be used in recirculation aquaculture systems as one of the stages of effl uent water treatment.
