dc.description.abstractDespite the high number of primary industry workers in many developing countries, the sector’s share of gross domestic product remains low. To eliminate economic disparities in developing countries, it is crucial to promote primary industries in rural areas. Diversifying agriculture through integration with fisheries could be one solution. This study focused on feed production utilizing rice bran, a byproduct of rice cultivation, to enable small-scale tilapia farming as a side business for farmers in Tanzania’s rice-growing regions. The results confirm the possibility of manufacturing feed consisting of 50% rice bran and indicate that the supplementation of this feed with local protein sources can satisfy the nutrient requirements of tilapia. Rice bran is prone to spoilage but this preservation issue has been resolved by using fermented rice bran. The use of rice bran, an agricultural residue is expected to increase, not only in tilapia feed, but also in livestock feed.
