The nutritional value of nauplii and metanauplii I of Artemia enriched with microalgae as food for freshwater prawn larvae (Macrobrachium americanum) was tested. The larvae were fed with three different diets consisting of Artemia nauplii (D₁), Artemia metanauplii I enriched with Tetraselmis suecica (D₂), and Artemia metanauplii I enriched with Chaetoceros calcitrans (D₃) from zoea (Z)II. Growth showed differences since the third week, and the highest and lowest growth was observed with D₃ and D₁, respectively. The first metamorphosis to post-larvae appeared with treatment D₃ at 9 weeks. Survival showed differences at the first week with D₁ and D₃ treatments, and D₂ showed the best survival up to week 4. From the sixth week to the end, treatment D₃ reached the highest survival. With treatments D₁ and D₂, all larvae died at the 9th and 10th week, respectively. D₃ was the most effective of the three diets.
