Surprising Food Trend in China

A new food trend has emerged in China, where diners are eating fish that have harmed crucial waterways.

The red swamp crayfish, native to Louisiana, was introduced to China by Japanese families as pets during the second Sino-Japanese war.

The freshwater crayfish is an integral part of China's late-night food culture.

According to researcher Sidney Cheung, the crayfish was originally brought to China as a pet in the 1930s and later released into the waters when Japanese families left the country.
