Larvae of the freshwater prawn (Macrobrachium rosenbergii) were reared to post-larvae in a closed recirculation system. Six treatments were designed where freshly-hatched Artemia nauplii were first given to the larvae for 3, 7, 11, 15, 17 and 25 days according to the treatment. After that (omega-3) HUFA-enriched Artemia were given until the 28th day at which time the test was terminated and evaluated. The requirement for (omega-3) Highly Unsaturated Fatty Acids (HUFA) for the larval stages of M. rosenbergii was confirmed by this experiment. Moreover, the longer the period of feeding on (omega-3) HUFA-enriched Artemia nauplii , the better the results in terms of growth, metamorphosis rate and stress resistance.
