Resumo: | In order to test the fertilization effect on Artemia production, six treatments of a mineral fertilization with di-ammonium phosphate (DAP) and urea (0.25*F; 0.5*F; 0.75*F; 1*F; 1.5*F; 2*F with F = 15 mg/L of DAP and 15 mg/L of urea) were compared to a control unfertilized. After the initial fertilization (day 0), a half a dose was brought once a week. At day 8, Artemia nauplii were inoculated in all tanks  at the rate of 50 nauplii per liter. Physico-chemical and biological parameters of the culture were analysed each week, during the 48 days of experiment. The results showed that the optimal dose is 0.75*F; it gaves the maximal phytoplanctonic biomass expressed by chlorophyll-a has and it allowed to obtain a maximal production of Artemia (cysts and biomass). Results of Artemia production were superior to those observed in a preliminary experiment using only the F dose.
