Different fishing activities generate a waste volume related to the processing species (viscera, heads and bones), the discards of the companion fauna, species of low commercial value and the losses related to handling problems. The biological silage could be the technology of choice to promote a sustainable waste management. Studies highlight the possibility of using a wide variety of carbohydrate sources, biological starters and fish waste fermentation conditions. This work could contribute to the fisheries that decide to adopt this kind technology in order to provide an innovative and viable recycling bioeconomy.
