The invention discloses a
mariculture method based on an offshore wind
plant. The method includes the following steps that firstly, single-
pile type
wind power foundations are inserted, a wind
plant area is formed in an enclosed mode, and culture facilities are fixed among the
wind power foundations; secondly, an equipment platform is arranged in the center of the wind
plant area, reinforcing rods are connected between the equipment platform and the
wind power foundations, and algal culture devices are fixed to the lower portions of the reinforcing rods to form an upper layer culture area; thirdly, fish culture net cages are fixed to the lower portions of the reinforcing rods to form a middle layer culture area; fourthly,
shellfish culture net cages are arranged on single piles of the wind power foundations to form a lower layer culture area; fifthly, different seedlings are placed on the algal culture devices according to seasons; sixthly, fry are placed in the fish culture net cages, and
algae falling from the upper layer culture area serve as bait; seventhly,
shellfish are placed in the
shellfish culture net cages, and
algae left over by fishes and fish excrement serve as bait; eighthly, artificial fish reefs are placed at the bottom of the wind plant area and used for bottom
sowing of shellfishes, fishes or shrimps and other organisms.
