|Description:||Aquaponics is a science that integrates animal aquatic production with vegetable culture in recirculating water systems. The performance of an aquaponics system using constructed semi-dry wetland with lettuce (Lactuca sativa L.) planted on treating wastewater of culture of shrimp Macrobrachium amazonicum was evaluated. Each aquaponics module consisted in four culture tanks (1 m3 tank-1), conical sedimentation tank (0.1 m3), circular holding tank (0.2 m3), and constructed semi-dry wetland (0.2 m×1.0 m×4.0 m). Post larvae (PL) shrimps with an initial average mass of 314±4.75 mg were stocked at density treatments in quadruplicate:(A) 40 shrimps m-2, (B) 80 shrimps m-2, and (C) 120 shrimps m-2. Our results showed the average final mass of shrimps had as light reduction at the density 80 and 120 shrimps. However, it did not differ significantly between the treatments. The ultimate survival and productivity were higher in density 80 and 120 shrimps. The maximum biomass productivity occurred at the treatment with density 120 shrimps. The aquaponics recirculation system using constructed semi-dry wetlands withlettuce adequately treated the water atthe densities tested. Various water quality parameters were deemed suitable for shrimp culture, but for lettuce not, especially the temperature.The shrimp density was inappropriate which limited the system to accumulate and increase the concentration of nutrients to vegetables with lessening the yield. Nonetheless, the system with higher density has higher nutrient content that plants demonstrated significantly better growth and yield. The results showed the potential use of organics waste generated in a family lettuce hydroponic production, but for a commercial production is indicated supplementation with nutrients like calcium, magnesium, and potassium in the water.|
