Valoración económica del uso de ensilaje de residuos piscícolas en la alimentación de oreochromis spp

Feeding in fish farming systems accounts for between 50% and 70% of production costs, with fishmeal being the most widely used animal protein source; therefore, lower-cost protein alternatives should be sought to improve profitability. The objective was to economically evaluate the use of chemical silage of trout viscera (CSTV) in the diet of red tilapia (Oreochromis spp), in four balanced diets so: T1 (control) and with inclusion of CSTV, T2 (10%), T3 (20%) and T4 (30%), supplied to 128 juveniles of red Tilapia with an average weight of 142,14 ± 4,74 g. The conversion rates and economic profitability rates were evaluated, as well as partial budget analysis. There were significant differences (P
