Abstract: In order to establish the management methods in snook Centropomus undecimalis (Bloch, 1792) broodstock (initial average weight 960 g), during 18 month three phases were developed. Fishes were marked, measured, weighed and distributed in 5 m3 fiber glass tanks (stock density 1.3 kg/m3). In the first phase (3 month), different feeding schedules were applied: 1. feeding in alternate days; 2. feeding every day excluding weekends; 3. feeding twice a day. Before maturation phase and during three month, enriched semi humid food was supplied. Finally, during 12 month, artificial feed was supplied. The appetite dynamics in fishes was influenced by the feeding schedule applied. When food was offered in alternate days, higher consumption was observed. Females showed higher growth rate than males. Condition factor (K) ranged between 1.08-1.31 and survival was 100%. Relationships large-weight in females and males were established.
