Surprising food trend sees diners eating fish that have harmed crucial waterways: 'An integral part'

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 were released into China's waters after the war, and have since become a persistent problem in the country's aquatic ecosystems.

Despite the harm they cause, the crayfish have become a popular food item in China, as reported by a YouTuber (@JHKDaily).
