Marine mammals are a food source in many countries around the world. Historically, they were hunted by coastal people, and in the case of aboriginal whaling , still are. This sort of subsistence hunting was on a small scale and produced only localised effects.

Blue foods are obtained using a range of different methods - from large deep-sea trawlers to small carp ponds, which date back to 2,500 years in areas such as the Mediterranean and China. Economically, blue food systems significantly contribute to global trade and livelihood support, benefiting millions of people worldwide directly or indirectly.
