“…Tilapias swim actively in the water column and feed on plankton (Ibrahim et al 2015), whereas prawns have benthonic habit and feed mainly on detritus and benthic organisms (Maciel and Valenti 2009). In integrated culture, tilapia may be fed with commercial floating diet, whereas prawns eat tilapia feces and leftover diet (Marques et al 2016;New and Valenti 2017). Such combination represents the farming of a fed species (Nile tilapia) with an extractive species (Amazon River prawn).…”

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.

“…In this context, the integration of multiple species of different trophic levels (IMTA) has been suggested to increase sustainability when compared to traditional monoculture (Chopin, 2014). The nitrogen accumulated in these systems may be assimilated by a species that has a complementary ecosystem function in relation to the target species (Chopin, Cooper, Reid, Cross, & Moore, 2012;Marques et al, 2016).…”

This work determined the nitrogen inputs, outputs and accumulation in compartments of stagnant earthen ponds for the monoculture and integrated multi‐trophic aquaculture (IMTA) of the Amazon river prawn (Macrobrachium amazonicum) and tambaqui (Colossoma macropomum), using recycled hypereutrophic water. A completely randomized experiment was designed with four treatments and three replications: PM–monoculture with 30 prawns/m2, FM ‐ monoculture with 3 fish/m2, IMTA ‐ polyculture with 30 prawns/m2 and 30 fish/m2 free, POLY‐CAGE ‐ polyculture with 30 prawns/m2 free and 40 fish/m3 in net‐cages. Animals, rain, water, feed, soil, gas, accumulated sludge, and suspended sediments were collected throughout the experiment to determine their nitrogen contents and to calculate the nitrogen budget. Results showed that much of the nitrogen available escapes to atmosphere as N2 (~40%–56%) after denitrification or accumulated within bottom sludge (~14%–42%). The remaining nitrogen was converted in animal biomass (~5%–21%) or was discharged to receiving waterbodies in the outlet water (~11%–13%). Feed management appeared to influence the major biological processes in the aquatic nitrogen cycle, such as photosynthesis and denitrification. The fish‐prawn IMTA systems converted approximately 53%–75% of feed nitrogen into harvestable products, which is more efficient than the 19%–46% of feed nitrogen converted in the monocultures. However, a large amount of nitrogen is accumulated in the pond bottom in all systems. An increased prawn density or the addition of a mud‐feeder species to the culture may enhance the incorporation of this material in harvested biomass, improving the efficiency of the systems.

“…The number of hatcheries dropped from 29 to 5 in Myanmar and from 81 to only 5–10 in Bangladesh (Anonymous, ). In Brazil, by 2007, all the private sector freshwater prawn hatcheries had closed due to economic factors (Marques et al, ). The scarcity of postlarvae impaired grow out farmers’ ability to maintain the regular supply to the markets.…”

“…These technologies are well developed and practised for long time with high survival and productivity (Valenti & Daniells, ; Valenti, Daniels, New, & Correia, ). However, inadequate seed supply remains a bottleneck for the expansion of the giant river prawn farming in many countries (Demaine, ; Kontara, ; Marques et al, ). Thus, some key aspects still lack scientific information.…”

Inadequate seed supply remains a bottleneck for the expansion of the Macrobrachium rosenbergii production industry. Nevertheless, the limitation is not technical, and thus, we presumed that fragile production chains and economic feasibility might be the major issues. Therefore, we investigated the intensification as a way to improve the system's profitability and resilience. We have reported relevant costs and revenues of hypothetical hatcheries stocking 50, 100, and 140 larvae per L in clear water recirculating systems. A Monte Carlo simulation assessed the risks associated with development and management. Data showed that all hatcheries are profitable. Nevertheless, 100 and 140 larvae per L reached better economic results than 50 larvae per L. With less than 40% of the selling price, high‐density hatcheries covered their costs and became profitable. The Monte Carlo simulation demonstrated that high‐density hatcheries are more resilient to production and marketing oscillations. However, the use of 140 larvae per L requires greater investment and is more susceptible to production risks and instabilities. Therefore, 100 larvae per L is the most appropriate stocking density for M. rosenbergii hatchery in clear water recirculating systems. Additionally, the scaled production, the adoption of realistic selling price, diversification of products and markets may strengthen the production chain and hatcheries resilience.
