WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries.
Aquaculture has continued to increase its demand for fishmeal and fish oil because these products have a high nutritional value and are easily digestible by other fish. Quality fishmeal provides a balanced amount of most essential amino acids, minerals, phospholipids and fatty acids, which help increase growth rates and overall production yields. These types of feeds are also absorbed more efficiently by cultured fish, which decreases water pollution levels and improves the efficiency of the production systems.
Humans consume capsules of fish oil as nutritional health supplements to reap the benefits of the omega-3 and amino acids EPA and DHA found in fish oil.
Fish oil and fishmeal contain quality protein and amino acids that are highly digestible by all animals, especially poultry, pigs, cows, sheep and goats. In turn, they provide plenty of usable energy. In fact, feeding animals fishmeal or fish oil is thought to help improve immune systems, reduce mortality rate in younger animals, reduce severity of inflammatory diseases, improve overall nutritional status, and generally reduce the cost of animal production.
Forage fish play a critical role in the marine food web because a variety of species including tuna, marine mammals, sharks, swordfish, and seabirds depend on them for food. Peruvian anchoveta, for example, is an anchovy of great significance to the entire marine food web. The Peruvian anchovy fishery is the world’s largest single-stock fishery, yielding around 7 million metric tons of fish annually, used mainly to produce fishmeal and fish oil.
