Abstract
Efficient feed distribution is essential in fish farming to minimize losses and optimize growth. This study evaluated the effects of four mealy feed distribution methods on the growth performance and economic efficiency of Oreochromis niloticus reared in earthen ponds during the grow-out phase. A total of 4 620 monosex juvenile tilapia (mean weight: 9.8?±?0.38?g) were stocked at a density of 2.2 fish/m2 across 12 ponds and fed over 126 days using one of the following methods: on-the-fly distribution, fixed floating frame distribution, self-feeder distribution or distribution on submerged tables. Significant differences (P<0.05) were observed in growth parameters such as weight gain and daily growth rate among the feeding methods, with the fixed floating frame showing the best overall performance with an average weight gain of 212.41?±?9.70?g and a daily weight gain of 1.60 ± 0.11 g. However, the self-feeder method demonstrated the highest economic profitability due to reduced labor costs. No significant differences (P>0.05) were noted in water quality or survival rates across treatments. These findings suggest that both fixed floating frames and self-feeders can improve feed utilization, but the self-feeder offers the most cost-effective option for small-scale pond culture of O. niloticus.
