Ice slurry is used for the preservation of aquatic products with high cooling efficiency and good preservation effect, which could utilize the seawater directly. In recent years, the study of ice slurry has become a hot spot. In this review, the research situation of ice slurry for the preservation of aquatic products in recent years at home and abroad were introduced. The combination of ozone and ice slurry was given to use the bactericidal and bacteriostatic effect of ozone to slow down the process of corruption of catches and extend the shelf life of products. Moreover, the future and development of the combination of ozone and ice slurry for the preservation of aquatic products were also prospected.
