“…The detritus is formed from the unconsumed food, faeces, debris of dead animals and plankton. The solid suspension in pond water occurs naturally due to the movement of prawns, as reported by Kimpara, Rosa, Preto and Valenti () in the culture of M. amazonicum . The bioturbidity increases the solids suspended in water and promotes the exchange of particles, ions and nutrients between the sediment and water column (Adámek & Marsálek ).…”

The effects of artificial substrate and night-time aeration on the culture of Macrobrachium amazonicum were evaluated in 12 ponds stocked with 45 prawns m À2 . A completely randomized design in 2 9 2 factorial scheme with three replicates was used. The combination of factors resulted in four treatments: with substrate and aeration (SA), with substrate and without aeration (SWA), without substrate and with aeration (WSA) and without substrate and aeration (WSWA). The presence of substrate in SA and SWA treatments reduced suspended particles (seston) by~17.3% and P-orthophosphate by~50%. The use of aerator (WSA and SA treatments) significantly (P < 0.05) increased the concentration of dissolved oxygen, suspended particles and nutrients in the pond water. These results indicate that the effect of substrate on turbidity and total suspended solids (TSS) values is opposite to the effect of the aerator. The aerators in semiintensive grow-out M. amazonicum farming lower water quality because they increased the amount of detritus and nutrients in the pond water. On the other hand, the use of artificial substrate reduces turbidity values, chlorophyll a, TSS and P-orthophosphate concentrations. Therefore, the combination of substrate addition and night-time aeration is not interesting because they have opposite effects.

“…The high contribution of inlet water to total nitrogen input observed in the present work is the result of the large volume of nutrient-rich water used throughout the culture to replenish evaporation and seepage (~10.8% daily). The nutrient-rich water is a feasible alternative for aquaculture because it has similar characteristics to the water found in aquaculture ponds and may represent a source of unpaid nutrients since it may be incorporated into reared animals (Kimpara et al 2011). …”

Nitrogen budget in integrated aquaculture systems with Nile tilapia and Amazon River prawn

2017

The present work aims to describe the nitrogen (N) budget in integrated aquaculture systems with Nile tilapia (Oreochromis niloticus) and Amazon River prawn (Macrobrachium amazonicum) in earthen ponds, with and without the addition of different substrates. The experimental design was completely randomized, with three treatments (without a substrate, with a geotextile fabric substrate, and with a bamboo substrate) and four replications. Diet was the major input of N in the systems, ranging from~65 to 71% and followed by inlet water (~26-31%). The portion retained in reared animals and periphyton ranged from~21 to 25% (being~21-24% in fish and prawns). The outputs that contributed most to the accumulation and release of N were, respectively, sediment (~24-38%) and N2 (~30-36%) emitted to the atmosphere. The addition of substrates did not improve the accumulation of nitrogen in the biomass of the target species. This suggests that the periphyton had a minor role on feed availability. In general, the systems were not efficient in using nitrogen since only~22% of all available nitrogen was retained into prawn and tilapia biomass. On the other hand, the emission of N 2 (an inert gas) to the atmosphere almost compensated the nitrogen supplied in the diet that was not assimilated by the reared animals and periphyton. In addition, data suggest that the integrated aquaculture in stagnant ponds may sequester substantial amounts of nitrogen from nutrient-rich aquatic environments and could be used as a mitigation tool.

“…The feed used in prawn farming has high percentages of phosphorus (minimum value of 1%) and the phytoplankton would absorb part of the phosphorus and high amounts of nitrogen, to maintain an adequate N/P relationship with the algae. Kimpara et al (2011) also observed a reduction in inorganic nitrogen concentrations and soluble phosphorus in the pond water associated with M. amazonicum, in relation to the supply water. The authors attribute this decrease to absorption by phytoplankton in the ponds, but they also observed an increase in total-N and total-P concentrations, as was also observed in our experiment.…”

“…In recent years, a number of studies have been undertaken to develop technology for the culture of this species (e.g. Preto, Kimpara, Moraes-Valenti & Valenti 2010;Araujo & Valenti 2011;Kimpara, Rosa, Preto & Valenti 2011). The present paper is part of a research initiative into the culture of M. amazonicum with a specific objective of saving water and reducing the amount of nutrient-rich effluents discharged into aquatic environments.…”

Effluent discharges from aquaculture can reduce water quality in receiving water bodies and that strategies or practices to reduce this are necessary. One possibility is to reduce, or eliminate, water renewal in grow‐out ponds. In this study, we eliminated water renewal in grow‐out ponds associated with the culture of 40 individuals m−2 of Amazon river prawn (Macrobrachium amazonicum). At the end of the culture period it was, however, necessary to drain the pond to harvest the prawns. An experiment was performed in triplicate, in which the water supply characteristics and harvest water characteristics of ponds were evaluated. To reduce these concentrations of total N and P, an aquatic macrophyte (Eichhornia crassipes, water hyacinth) treatment system (CWs) was adopted. The water characteristics in the CWs were evaluated after 1, 3, 7, 14 and 21 days. The water supply of ponds presented the average concentrations of 0.67 ± 0.32 mg L−1 and 17.4 ± 14.7 μg L−1 of total‐N and total‐P respectively. The harvest effluent of ponds had elevated concentrations of different forms of nitrogen (4.44 mg L−1 of total‐N) and phosphorous (100.9 μg L−1 of total‐P). After 1 day of the experiment we found the following reductions in key nutrients in treatment system containing E. crassipes: 90%, 78% and 45% reductions in the concentrations of particulate matter, orthophosphates and nitrates respectively. We noted that after 3 days the nitrates had been reduced by 53%. We concluded that 3 days of this treatment was sufficient for the removal of the additional nutrients that had accumulated in the Amazon river prawn ponds.
