A portion of 150 g of fish can provide about 50–60 percent of an adult’s daily
protein requirements. In 2010, fish accounted for 16.7 percent of the global
population’s intake of animal protein and 6.5 percent of all protein consumed.
Moreover, fish provided more than 2.9 billion people with almost 20 percent of their
intake of animal protein, and 4.3 billion people with about 15 percent of such protein.
Fish proteins can represent a crucial nutritional component in some densely populated
countries where total protein intake levels may be low.
