Resumo: 	This study defines rearing parameters for mass products of 30-day old post larvae. Continuous lighting (600 lux) optimizes the predatory activity and suppresses the feeding rhythm. For 4-5 mm larvae (15 days), food ingestion slows down if the prey concentration in the tank is below 5 rotifers/ml, while there is no such threshold for 6-7 mm larvae (22 days). The rotifer Brachionus plicatilis , between 100 and 200 mu m, is an adequate initial prey, it can be replaced by Artemia salina for 7-8 mm larvae (30 days). It is observed that free amino acids and essential fatty acids contents have a prominent role in larvae growth; docosahexaenoic acid (C22:6n-3) content could be determined. Finally, the development of the swim bladder is facilitated by the renewal of water and air, and by continuous elimination of the superficial oily film through a blower combined with a floating trap.
