Abstract:
The issue of food quality and safety has already drawn widespread attention from the society. Crayfish is an important economic shrimp that has emerged in recent years. China is its largest producer. In 2018, the production of crayfish reached 1,638,700 tons, with economic profit as 369.7 billion yuan. At present, the breeding mode of crayfish mainly includes rice-crayfish and pond-crayfish cultures, with the rice-crayfish culture becoming one of the main ecological agriculture development modes. However, the existing crayfish standards are less developed (with most of them being transferred from the existing food standards), and there is a lack of specific standards based on the characteristics of crayfish species. Therefore, it is necessary to sort out the relevant standards for crayfish in China and provide a basis for the standard development. In this article, a focus is placed on the quality and safety, production and industrial status of crayfish. The quality and safety indicators and limit requirements related to crayfish as well as the production standards related to the comprehensive rice-crayfish culture are introduced separately. According to the characteristics and shortcomings of the existing standards for crayfish, the prospects and research directions associated with these standards are also given in order to provide a theoretical basis and reference for the government and the standard-setting personnel.
