| description | The objective of this study was to evaluate dynamics of nitrogen in intensive whiteleg shrimp (Litopenaeus vannamei) culture in tanks and integration with hybrid constructed wetlands (CWs). The CWs planted with Typha orientalis (C. Presl) and unplanted CWs were arranged inthree replications, while control (without CWs) was duplicates. Water from the shrimp tanks was distributed to the hybrid CWs and their outlets were recycled back to the shrimp tanks that were studied at 5-10‰ of salinity. The hybrid CWs consists of a vertical subsurface flow (VF), horizontal subsurface flow (HF) and surface flow (SF). The entire systems were operated at a recirculation rate of 11.4 L/min (equivalent to 100% volume shrimp tank per day). Water quality in the shrimp tanks was monitored every two weeks. The results showed that while the concentrations of NO2-N and NH3-N were increased overtime but they were still in the suitable range for whiteleg shrimp growth. Taken together the results indicated that the wetland system helped to maintain water quality in intensive recirculating shrimp culture tanks without water exchange. |
