Resumo: | A simulation was conducted to determinate the impact caused by the combination of Litopenaeus vannamei respiratory rate (mg O2 shrimp-1 h-1), the behavior of SOTR (kg O2 h-1) of mechanical aerators as a function of salinity, as well as the oxygen consumption rate of the pond water and soil (mg O2 L-1 h-1) on the aeration of shrimp ponds (1, 10, 50 and 100 ha) stocked with different densities (10, 40 and 120 shrimp m-2), salinities (1, 13, 25 and 37 ppt), temperatures (20, 25 and 30°C), and shrimp wet weight (5, 10, 15 and 20 g). Results showed that under lower salinity, with larger shrimp, and higher stocking density, higher will be the quantity of required 2-HP aerators to keep dissolved oxygen over 50% saturation. In addition, under low salinity, with 5 and 10 g shrimp, independent of stocking density, more aerators per hectare are required and electricity cost is higher at 20°C and salinity 1 ppt. Less aerators and lower electricity cost was observed at 30°C, salinities of 25 and 37 ppt, and shrimp of 15 and 20 g.
