Chinese squid fishing industry has a large scale, and its catch is among the top in the world. Meanwhile, squid processing industry is the main component of domestic aquatic products processing industry. With the development of economy and the change of social demand, the economic benefits brought by the simple processing of squid can not meet the development needs of the industry, and the burden and pollution of a large number of squid processing wastes on the environment are caused. The development and utilization of squid processing by-products to improve the added value of squid processing products has become a research hotspot in recent years. In this paper, the different parts of squid processing by-products (viscera, skin, ink sac, gonad, eye, cartilage, head and fin) were introduced. The common utilization ways, composition and efficacy of bioactive components were described respectively. The existing research progress and practical development and application of each bioactive component were listed, which provided theoretical reference for the deep processing and high-value utilization of squid by-products, as well as a theoretical basis for the healthy development of squid processing industry.
