The aim of this study was to highlight the potential economic benefits of fisheries industrial waste silage by the dint of its ability to be recycled efficiently in animal feed. Fish silage was produced by acid hydrolysis. The fish silage was ripened and became half-liquid, at room temperature in 12 days. Its odour became less pungent and was deemed to have an acceptable malt smell. The silage cost was found to be 0.72 TL/kg. The results of this study established that, the use of silage instead of fish meal, reduces the cost of feed by 21%. Therefore fish waste products, previously considered as a refuse and causing environmental pollution, can be reintegrated into the economy.
