Abstract:Abstract：The wastewaters generated in aquatic product processing industry contain a high organic load，and therefore they should not be discharged directly without effective treatment to prevent a negative impact on the environment.These wastewaters contain a large amount of potentially valuable proteins.The proteins in the effluents could be recovered and used to prepare feed or food ingredients or bioactive peptides through precipitation and concentration.In this review，the research progress of recovery and recycle of protein from wastewater in aquatic product processing industry was discussed.This paper could provide a basis for the green and high value production of aquatic products.
