Production History Danjiangkou is known as the “Chinese Water Capital” and has more than 40 kinds of precious fish, mainly squid, squid and silverfish.

The completion of Danjiangkou Reservoir provided a relatively closed ecological environment system for the culture of carp. In June 2007, the carp of Danjiangkou was artificially hatched, and in 2009, it was successfully cultivated and won the third prize of provincial scientific and technological progress. Danjiangkou squid has formed more than 10 varieties of fresh fish, chilled fish, air-dried splits and flavored convenience foods. Geographical environment Danjiangkou squid is mainly based on refuge culture, large reservoir natural proliferation, cage culture, feeding on small fish and shrimp, at the top of the food chain. The rich bait resources of Danjiangkou Reservoir provide sufficient nutrition for Danjiangkou carp. By the end of 2011, the large-scale aquaculture of squid in Danjiangkou City reached 10,000 mu, with a production of 4 million kilograms and an output value of more than 200 million yuan. The farmers can increase their income by 5,000 yuan. The nutritional value was tested by the authoritative department. The Danjiangkou squid was compared with the squid test data in other places: the protein content was 19.0%, which was 2% higher; the vitamin A was 13.2mg/kg, which was 1.8 higher. Percentage; vitamin C measured 14.0mg/kg, 2.5 percentage points higher; 17 kinds of amino acid total measured 18.7mg/kg, 1.5 percentage points higher; calcium, phosphorus, iron and other nutrients and inorganic salts They are all higher than other places.
