Cod is the general name of cod and some fishes of other families of Codiformes, with more than 50 species, which is one of the main edible fish.
Cod is native to the cold waters of the North Atlantic from northern Europe to Canada and the eastern United States. At the beginning of the 20th century, the main producers of cod were Canada, Iceland, Norway and Russia, and Japan was mainly in Hokkaido.
In 2000, a study published by WWF showed that the global catch of Atlantic cod had decreased by 70% since 1970.
Cod became an endangered species. Later, the Atlantic cod population, once considered pessimistic, gradually recovered, with an annual catch of about 800,000 tons.
There is no Atlantic cod in China waters, but some cod fishing countries, such as Russian, transport their catch to the port of China. With the low cost of human resources in China, China's reprocessed cod products can be sold all over the world, and China has become the largest supplier of Atlantic cod products in the European market.
