Silage process allows the recovery of nutrients contained in fish waste and can be recycled as animal feed. Biological silages usually include the incorporation of an extra carbohydrate source to allow microbial development. The carbohydrates can generally be selected according to availability in the region, costs or can be obtained from the side-streams of other industries or productions. In this regard, the processing of dairy products has been associated with a high environmental impact (Palmieri et al., 2017). As an example, cheese manufacturing generates a large amount of whey representing about 85-90% of the processed milk volume. Worldwide whey production is estimated at around 180 to 190×106 ton/year and just 50% is processed (Baldasso et al., 2011). The aim of this work was to evaluate the feasibility of milk whey powder as carbon source for fish waste fermentation.
