A study was carried out from April 12 to June 10, 2024, at the Layo experimental station (Dabou) to evaluate the growth performance and survival of juvenile Chrysichthys nigrodigitatus in an enclosure. A total of 1,200 fish with an average initial weight of 38.93 ± 15.09 g and an initial length of 162.26 ± 17.52 mm were used for this experiment in an enclosure with a density of 6 individuals per m3. The fish were fed at 10% of their biomass with Koudijs feed. One hundred fish, sampled at random each week, were weighed and measured individually. The results showed that the averages for temperature (29.26 ± 0.19°C), dissolved oxygen (6.20 ± 0.18 mg/l) and pH (6.97 ± 0.48) were in line with recommended standards for rearing this species. With regard to zootechnical performance, values of 91.60 ± 10.85 g, 214.7 ± 11.81 mm, 1.6 g/d and 100% were observed at the end of rearing, respectively for Average Weight, Average Length, ADG and Survival Rate. However, growth performance was exponential in weeks 1, 4 and 5. On the other hand, they slowed down in weeks 2 and 3. In short, it would be interesting to repeat this study in the non-rainy season to gain a better understanding of the factors influencing the growth of this species.
