Resumo: | Trials on the seabass weaning in atlantic marshes (Roux, 1993), have shown that the use of frozen prey improved this step and reduced his resulting stress. During the present study, which must confirmed these preliminary results, three alimentary sequences were tested. 1) natural zooplankton, weaning pellets, as control, 2) natural zooplankton, inert artemia (intensively produced), weaning pellets, 3) natural zooplankton, natural frozen zooplankton (harvested), weaning pellets. The achieved results show that weaning with intermediary phases (sequences 2 or 3) yield best results. Furthermore the phase with artemia yields, systematically, better results than with harvested zooplankton ; then artemia seems a excellent substitute food representing a sustainable nutritional input. A sufficient duration weaning (8 days) is preferable than a fast weaning. The multiplication of the food distribution points improve the final weaning performances.
