Floating artificial fish reef

The invention discloses a floating artificial fish reef. During preparation, the floating manual fish reef is characterized in that an adhesion base material is bonded to a floating body material and a suspender by using an adhesive or cement, the suspender is suspended below the floating body material after being cured, and a counter weight is suspended below the suspender. The floating artificial fish reef is arranged on the euphotic layer of sea water in an aquaculture zone, so that the adhesion growth of algae, shellfishes and microorganisms is facilitated, the water quality of the aquaculture zone is improved, and the generation of eutrophication is inhibited.
