The experimentation for rearing of Polydactylus quadrifilis and Pomadasis jubelini fishes at the Layo’s Experimental Aquaculture Station allowed to feed them with a food composed of 40% protein, supplemented with shrimp such as Penaeidae families (38, 4%), Palaemonidae (20%) and Aristeidae (19%). A mortality rate of 100% is observed in large specimens, while those of small size have shown high survival rates, ranging from 57%to 100%. Specific growth rates ranged from 0.9 to 2.8% for Polydactylus quadrifilis individuals and 1.1% to 2.7% for those of Pomadasis jubelini. The conversion index ranged from 1 to 2.46 for specimens of Polydactylus quadrifilis and from 0.9 to 2.2, concerning those of Pomadasis jubelini. The coefficients of variation stabilize between 11% and 17% for specimens of Polydactylus quadrfiflis, and the Pomadasis jubelini individuals have theirs stabilize between 10% and 16%. These species have aquaculture potentials to develop through a control of their breeding conditions.
