Abstract: When the biofouling on the marine aquaculture cage are too much, it will affect the exchange volume of the internal and external water bodies in the cage, shorten the service life of the netting, and even endanger the health of the aquaculture organisms. How to solve the attachment of biofouling has become a difficult problem in developing marine aquaculture cages. This paper briefly describes the current situation of antifouling technology of marine aquaculture cages at home and abroad, focuses on the research progress of antifouling technology of marine aquaculture cages, such as mechanical cleaning, coating antifouling method, metal alloy netting antifouling method, points out the problems faced by the current antifouling technology of marine aquaculture cages and gives suggestions. The aim of this paper is to provide reference for the antifouling biotechnology of marine aquaculture cages and the sustainable health development of mariculture industry.
