Abstract In 2021, the total production of crayfish farming in China was 263.36 million tons, and about one million tons of crayfish shells were produced as a byproduct from crayfish processing. At present, crayfish processing enterprises mainly adopt manual shelling, and the majority of crayfish shells and other by-products are used to prepare feed, which leads to low utilization rate and low added value. In view of these problems, this paper reviews the major crayfish shelling techniques, namely manual shelling, pretreatment shelling and mechanical shelling, as well as the use of crayfish shells for the production of feed and the extraction of active substances. It is expected that this paper can provide a reference for developing safe and efficient crayfish shelling techniques and equipment and for exploring the application of crayfish shells, and provide new ideas for promoting the strengthening and extension of the crayfish industry chain.
