Fish are 100,000 times more numerous on Earth than humans. This is mainly due to the size of several species. Or the small ones that do not have time to grow and are quickly devoured in the food chain. We can find among the most common : anchovies, sardines, mackerels, herrings, …

According to the FAO, each year, between 100 and 150 million tonnes of fish are fished. This figure remains stable over the last 20 years. Except that today, almost 40% come from aquaculture. Illegal fishing represents a third of legal fishing. It is estimated that this represents 2,740 billion of fish killed each year. That’s 86,000 fish per second! By a fleet of 1.3 million boats.

Only 3 species out of the 54 most caught are able to regenerate fast enough to replenish the stock each year. That means that in 2040, the current overfishing will lead to a major crisis of the sector with quantities that will have drastically decreased.

There is a total of 45 quadrillion (million of billion) of fish on Earth.
