ABSTRACT
Every year millions of tons of by-products, discards, and bycatches are generated by worldwide activities in fishery and aquaculture. In most cases, these wastes represent an unethical underutilization of fish stocks and complicated and ineffective management and harm marine ecosystems when discharged without prior treatment and depuration. Valorization of marine food waste biomass as a renewable source of chemicals and biocompounds is an attractive alternative. These materials constitute a valuable point of supply of biopolymers, enzymes, bioactive compounds, oils, and ingredients for animal feed or microbial and cell culture media. In this chapter, we have summarized recent information related to the different alternatives to valorize fishery wastes to obtain high-added value bioproducts.
