Abstract

Juveniles of common snook C. undecimalis were stocked in cages of 4 m3 (2 x 2 x I m) at densities of 7.5 and 12.5 org/m3, were fed daily to 10% of biomass with mojarra Cichlasoma urophthalmus. The fish had an initial average length and weigth of 11.21 cm and 11.3 g, respectively. After 105 days of culture, snook of 7.5 org/m3 reached 21.3 cm and 58.1 g ,with a survival of 80 % and a average feed conversionration (FCR of 3.2). While snook stocked at 12.5 org/m3 reached a length of 18.2 cm, a weigth of 36.5 g, with a survival of 78 % and a FCR of 2.87. Growth of snook under these conditions is considered acceptable, taking into account their carnivorous nature. However, further investigations into fry supply, feed formulations and health management will be required to determine the viability of culture of this species
