A study was conducted from February 20 to April 20, 2025, at the Layo experimental station (Dabou) to assess the effects of commercial feeds on the growth performance and survival of Oreochromis niloticus larvae. Thus, 300 individuals of average weight 0.02± 0.001 g and average length 11.13± 1.03 mm were divided into two groups of 150 subjects each (Batch 1: fed with Koudijs feed and Batch 2 : fed with Dibaq feed). The batches were treated in triplicate at a density of 1 individual per liter of water. Each week, 10 fish sampled at random from each happa were weighed and measured individually. Physico-chemical parameters were also measured. At the end of the trial, all live fish were counted by batch and measured. The results showed that the average physico-chemical parameters obtained in the happas were 27.63 ± 0.08°C for temperature, 6.23 ± 0.12 mg/l for dissolved oxygen and 6.73 ± 0.06 for pH. These values were in line with recommended standards for rearing this species. In terms of zootechnical performance, batch 2 performed best in terms of weight (1.65 ± 0.29 g), length (45.2 ± 2.96 mm) and ADG (0.018 ± 0.006 g/d). In contrast, the survival rate of larvae fed with Koudijs (Batch 1) was 99.33 ± 0.88%, higher than that of individuals fed with Dibaq (96 ± 1.33%). Similarly, the biomass of batch 1 (49.66 ± 0.44 g) was higher than that of batch 2. In short, it would be interesting to repeat this study over a longer period for a clearer conclusion.
