| Sumario: | Experiments were carried out in a commercial marine shrimp farm in order to evaluate the use of two diets in Litopenaeus vannamei post-larvae, during nursery phase, on physiochemical wastewater quality. Two feeding methods were adopted: Commercial Feeding Method (MAC) and Artemia Feeding Method (MAA).0 The nursery tanks (60 m3) were provided with 19 days post-larvae (PL19) with a stocking density of 16PL/liter. After 10 days of culture, the concentrations of nitrogen (ammonia, nitrite and nitrate) and phosphorus compounds (total phosphorus and orthophosphate) in the nursery tank were smaller for MAC, rather than MAA treatment (p < 0.05). Consequently, MAA treatment induced low levels of daily compounds increment, thus contributing to a significant reduction of the nutrients that caused water eutrophication. |
