The researchers tested different diets to feed giant freshwater prawn larvae instead of Artemia nauplii. They found that gradually replacing up to 50% of Artemia nauplii with wet or dry diets resulted in good growth and survival of the larvae. However, abruptly replacing 50% of Artemia nauplii with artificial diets had a negative impact on larval development. Weaning from Artemia nauplii to artificial diets could start at stage V and increase gradually up to 50% by the postlarva stage. Providing artificial diets in different particle sizes based on the larval stage, increasing from 250 to 1000 μm, was important for successful larval rearing.
