Abstract: Enzymatic hydrolysis of aquatic proteins in controlled conditions is one of the most important ways to increase values of the low-value aquatic products and of the by-products in aquatic product processing.The choice of enzymes, the flowsheet for enzymatic hydrolysis, the reaction mechanism of enzymatic hydrolysis and the applications of enzymatic hydrolysates were introduced in this paper. The general situation of the utilization of aquatic proteins by enzymatic hydrolysis was reviewed. Meanwhile, the research and application trends of enzymatic hydrolysis of aquatic protein resourses were envisaged in this review.

Key words: aquatic protein resource, controlled enzymatic hydrolysis, value-increment
