Fish meal

Fish meal is a protein-rich feed ingredient made by cooking, drying, and grinding whole fish or fish-processing byproducts. It supplies concentrated protein and minerals to livestock and aquaculture diets.

Fish meal processing: A sequence of cooking, pressing, drying, and grinding that turns fish or fish byproducts into meal. Cooking and moisture removal concentrate nutrients and make the product storable.
Aquaculture feed: Feed formulated for farmed aquatic animals, including fish and crustaceans. Fish meal supplies concentrated protein and palatable nutrients in many aquaculture diets.
Industrial fishing: Large-scale commercial capture of wild fish using mechanized vessels and gear. Dedicated reduction fisheries have supplied whole fish for meal and oil production.
Forage fish: Small schooling fish that feed on plankton and serve as prey for larger animals. Many reduction fisheries target forage fish, which also support marine food webs.
Soybean meal: A protein-rich feed ingredient produced from soybeans after oil extraction. It is a widely used plant-protein alternative, with a different amino-acid profile and supply chain.
Fish meal quality: The nutritional value and physical condition of fish meal, shaped by raw materials, processing, and storage. Heat damage and oxidation can reduce the value of the finished ingredient.
Salmon farming: The commercial rearing of salmon in freshwater and marine facilities. Salmon diets have historically used fish meal as a major marine-derived protein source.
Fish processing: The transformation of harvested fish into food products and other usable materials. Trimmings and other byproducts from processing can be rendered into fish meal.
Marine food web: The network of feeding relationships among organisms in marine ecosystems. Removing fish for meal can alter prey availability for predators and other consumers.
Insect meal: A feed ingredient made by drying and processing insects into a protein-rich meal. It can replace some fish meal while relying on a different production system.
