Abstract

Aquaculture Potentials of Estuarine and Marine Species, Polydactylus quadrifilis and Pomadasis jubelini at the Layo Experimental Aquaculture Station (Côte d’Ivoire) KONAN Kouassi Sylvain, YAO Laurent Alla, YOBOUET Ahou Nicole, BLE Mélécony Célestin, Yao Kouakou Abstract 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. Full Text: PDF DOI: 10.15640/jaes.v7n1a10
