Abstract：According to the marine environment and fishery resources of the Zhoushan archipelago, a six prism type artificial reef was designed to improve the local marine ecology and fishery. Based on the Fluent software, the CFD simulation of the fish reef was carried out, the maximum height of the upwelling is 2.5 times of the height of the fish reef, and the length of the back vortex is about 9.6 times of the height of the fish reef, which indicates that it has a good hydrodynamic performance. According to the simulation result, the experiment of the fish reef was carried out, and the results are consistent with each other. Finally，according to the simulation and experimental results, combined with the practical experience ,the reasonable layout of the fish reef was carried out, after a period of observation, it was found that the species richness and activity of the species in this area was greatly promoted, and the attracting effect was good.
