Fish

Many species of fish are caught by humans and consumed as food in virtually all regions around the world. Fish has been an important dietary source of protein and other nutrients. The English language does not have a special culinary name for food prepared from fish like with other animals , or as in other languages (such as Spanish pez vs. pescado). In culinary and fishery contexts, fish may include so-called shellfish such as molluscs, crustaceans, and echinoderms; more expansively, seafood covers both fish and other marine life used as food. Since 1961, the average annual increase in global apparent food fish consumption (3.2 percent) has outpaced population growth (1.6 percent) and exceeded consumption of meat from all terrestrial animals, combined (2.8 percent) and individually (bovine, ovine, porcine, etc.), except poultry (4.9 percent). In per capita terms, food fish consumption has grown from 9.0 kg (19.8 lb) in 1961 to 20.2 kg (45 lb) in 2015, at an average rate of about 1.5 percent per year. The expansion in consumption has been driven not only by increased production, but also by a combination of many other factors, including reduced wastage, better utilization, improved distribution channels and growing consumer demand, linked with population growth, rising disposable incomes and urbanization.
