Abstract: Increase in fish feed cost leading to non-lucrative fish farming can be counteracted by utilizing inexpensive oil cakes as ingredients. The present study was aimed to use low cost sesame and sunflower oil cakes as ingredients in feeds for Labeo rohita fingerlings. Doughs made from oil cake powder with 60% moisture content were fermented for seven days using inoculum with a proportion of probiotics powder (Aqualact/Rhodomax/Uni-Nutrich Plus):jaggery:water: :5g:25g:160ml (per kg of oil cake substrate). The fermented oil cakes were incorporated at a rate 35% to 40% in the test diets. Fingerlings of Labeo rohita, fed with test diet containing 24h Aqualact fermented sesame oil cake showed highest weight gain (3.66 ± 0.04 g) with lowest FCR (1.991 ± 0.003) and highest protein value (13.81± 0.02 ) in the carcass. Fingerlings group fed with the same test diet also showed highest Protein efficiency ratio (1.683 ± 0.003), Apparent protein net utilization (27.45 ± 0.07) and Lipid productive value (29.26± 0.90). These fermented oil cakes are found to be viable alternatives to other costlier fish feed ingredients.
