The loss of marine biodiversity also has negative consequences for the more than 3 billion people in the world who live off the richness of the seas and coasts, according to the United Nations UN , as well as for the fishing fleets that are forced to sail hundreds of kilometres further to cast their nets in more productive waters. These forced journeys in turn create new problems such as the overexploitation of other fishing grounds and the outbreak of territorial conflicts, especially off the coasts of Africa, Latin America, and south and north-east Asia, the continent with the greatest fishing activity in the world.
In addition, the impoverishment of the seas, together with the lack of resources in the poorest fleets, encourages illegal fishing, which generates 36 billion dollars annually, degrades marine ecosystems and endangers food security. The State of World Fisheries and Aquaculture, a report published biannually by the FAO, warns that fish production has doubled since In , it broke its historical record with million tons and an average consumption of This exponential increase in demand has led to the overexploitation of species such as the Alaska pollock, the anchovy and skipjack tuna, among others, which endangers food sustainability.
The state of the world's fisheries. Sustainable fishing is a more artisanal and small-scale method with social, economic and environmental benefits, some of which are based on the FAO Code of Conduct for Responsible Fisheries.
Some of these are summarised below:. Protects marine fauna. Sustainable fishing respects marine ecosystems and adapts to the reproductive rate of fish to maintain a balance and ensure the survival of all species.
Uses selective methods. Sustainable fishing rejects the indiscriminate capture of fry and endangered species or those without commercial value. Avoids waste. In sustainable fishing, the bycatch is used, for example, to make fishmeal to minimise food waste. Contributes to food security. Generates jobs and is more responsible. However, food sources from our oceans, lakes and rivers also play a large part in feeding the world, and deserve their place in the discussion.
After all, three billion people rely on seafood as a primary source of protein, and this number will only continue to grow. The principle findings are straightforward and important. Thriving, resilient oceans that support more fish, feed more people and improve prosperity are within reach. With every fisheries management success, the prospects improve for healthy oceans that help sustain the well-being of nations, communities and people around the world.
Aquatic sources of food are harvested from fresh and saltwater. This comes in many forms, including the actual fish fresh or frozen but also fish meal and fish oil that are used to feed both farmed fish and land animals, or added as supplements to other food products.
Hundreds of millions of people rely on fish for these nutrients , and are at risk of malnutrition if fish populations continue to decline. Unfortunately, with failing management and new risks from climate change, fish populations are declining globally, meaning that not only are important sources of protein disappearing, but that the uptake of micronutrients— especially in vulnerable populations — is also declining.
