The results on water quality and meteorological data are shown in Table 1. During cultivation the pond showed little variation in temperature (26.7 ºC to 28.5 °C), a mean salinity of 31.2 ± 2.0 and slightly alkaline mean pH (8.1 ± 0.3). Transparency did not exceed 33 cm and maximum turbidity was registered at the end of the experiment (116 NTU). The dissolved nutrient content of the water was high throughout the study. Ammonium (NH4) showed the highest concentrations, ranging from 1.68 to 15.15 µmol L-1; nitrite (NO2) ranged from 0.39 to 0.68 µmol L-1; nitrate (NO3) between 0.14 and 1.03 µmol L-1 and orthophosphate (PO4) ranged from 0.13 to 3.22 µmol L-1. In general, the physical and chemical parameters values increased with the development of shrimp at the pound
