Abstract

Argyrosomus regius is a new species of interest in aquaculture. Nevertheless, few are the works published on this species and less even in larvae culture and weaning. In this study 2 experiments were done, in tanks of 15 l, with larvae of 15 and 34 days of life, respectively to which 2 different protocols for their weaning were applied. The provided food consisted of a mixture of Artemia and microdiet to different concentration. In experiment A, the best results of growth were observed in treatment 1 and worse in treatment 3, nevertheless in the survival the opposite happened. In experiment B, the best results they were reached with larvae submitted to low density and with significant difference between treatment 1 and 2, in survival no significant differences were found between the different treatments.
