Un estudio tuvo como objetivo determinar niveles seguros de amoníaco y nitrito a diferentes etapas de vida del langostino del Río Amazonas, basándose en la hipótesis de que las primeras etapas de desarrollo de M. amazonicum son más sensibles al amoníaco y al nitrito que las etapas posteriores. El monitoreo de esta variable es importante para evitar pérdidas, principalmente en larvicultura y recirculación. 

A study aimed to determine safe levels of ammonia and nitrite to various life stages of the Amazon river prawn, based on the hypothesis that the early stages of development of M. amazonicum are more sensitive to ammonia and nitrite than later stages. The monitoring of this variable is important to avoid losses, mainly in larviculture and recirculation. 

Proper monitoring of water quality in aquaculture production systems is critical to enable appropriate and timely management decisions. It requires reliable equipment, trained technicians that follow instructions and apply quality control measures, proper reagents and calibrated equipment, and appropriately collected water samples that are promptly analyzed. 

Biological filtration is one of the critical required unit processes in recirculating aquaculture systems. Non-corrosive filter media with large amounts of surface provides area for nitrifying bacteria cells to colonize. 

The intrinsic values of better feeds directly affect shrimp growth and performance in a positive way, but because better feeds produce less waste materials in culture systems, they also result in improved water quality that indirectly improves shrimp performance. 

One simple method of treating high-nitrogen wastewater in shrimp aquaculture is the use of sequencing batch reactors, which are simple in design. 

Biofloc systems enable more intensive tilapia production. The fish adapt to the conditions within biofloc systems and grow well by utilizing the bioflocs as a feed source.
