Abstract:Puffer fish has tender meat，diverse nutrients，and high processing and utilization value.However，the processing and utilization level of puffer fish in China is still in its infancy，and the added value of the products is low.With the continuous expansion of the breeding scale and the increasing processing volume，massive processing by-products are accumulated and landfilled，which is the bottleneck problem that needs to be solved urgently in the puffer fish industry.To facilitate the research on the processing and utilization technologies of puffer fish，this paper systematically summarized the development status of puffer fish breeding industry，discussed the nutritional value of puffer fish，introduced the processing technologies of puffer fish in China and abroad，analyzed the comprehensive processing and current situation of high-value development and utilization of puffer fish leftovers（fish skin，fish liver，and testis），aiming at providing references for improving the utilization value of puffer fish.
