Even today, relatively primitive societies in the South Pacific and South America depend largely on fish for food; while in many industrialized nations, fish still constitute a major part of the diet. It is said that the search for codfish led French fishermen to the discovery of Canada and that villages sprang up on the coasts of Norway, Scotland, Japan, and other countries wherever shoals of herrings regularly came close to shore.
