Our Crayfish are predominantly wild caught by creel nets from inland waters of China.
The Crayfish species is Procambarus Clarkii, originally a native to America, is thought to have been unintentionally introduced to China in during the 1920 & 1930s when trading ships from America dropped their water ballast containing crayfish larvae the Yangtze river. Over the following years crayfish then moved west inland and colonised the large lakes in Jaingsu, Anhui, Hubei, Hunan and Jiangxi provinces.
Commercial fishing and processing started about 20 years ago.
Because crayfish are not seen to be indigenous to China, the Chinese Government does not monitor and control fishing efforts. The industry does however enforce a minimum catch size. Small crayfish are thrown back from the creels. This is enforced by the factories having a minimum size specification below which the fishermen are not paid.
