Abstract: African catfish Clarias gariepinus culture remains undeveloped in Cote d’Ivoire due to the lack of locally quality feed, fingerlings and the high cost of imported feeds. Because of the importance of feed in the aquaculture development, three different isoproteiques 40% feeds SG1, SG2 and G were formulated with locally available feedstuffs in three fish farming agroecological area for Clarias gariepinus fingerlings growth. C. gariepinus fingerlings average weight 6.76±0.23 g were fed with these three feeds in three replicate groups, three times a day (09:00, 13:00 and 17:00 h) at 10% of total biomass during 60 day in outdoor hapas in earthen ponds. During the trial, water quality parameters recorded in the ponds were within suitable range for Clarias gariepinus culture. At the end of feeding trial, average daily growth (0.25-0.36 g/d), specific growth rate (1.89-2.39%/d) and survival rate (96.84-98.73%) values recorded show the good quality of the simple three composed 40% protein feeds formulated for C. gariepinus fingerlings. However, feed G formulated with the accessible feedstuffs for Guinean area recorded the best response of growth, feed utilization and survival. Protein content of the carcass of the three groups of fish fed ranged between 17.12±1.73 (SG2) and 18.34±0.04% (SG1) and did not differ significantly. Highest significantly values of fish carcass crude lipid level were recorded from fish fed feed SG1 (4.83±0.05%) and SG2 (4.71±0.56%) when fish fed feed G presented the lowest value (3.91±0.19%). The availability of feedstuffs used in feed production, the affordable prices of these three feeds produced, their good nutritional quality and the good growth and survival recorded with them could promote their use to improve Clarias gariepinus fingerlings culture in Cote d’Ivoire.
