Before the artificial fish reef is put in, the seaweed culture substrate and the fish reef substrate are connected up and down to form an integral structure. The fish reef substrate is easier to sink than the seaweed culture substrate. Seaweed spores are filled in the seaweed culture tank and thrown into the sea. The artificial reef sinks into the sea and is suspended at a certain height. The buoy floats on the sea surface, and the seaweed spores in the seaweed cultivation tank begin to grow. At the same time, the hook is slowly corroded by seawater. After breaking away from the drag hook, the fish reef substrate continues to sink. At this time, the seaweed culture substrate pulls the fish reef substrate by the pull rope, and the seaweed grows attached to the culture plate.

The impurities that are easy to block the cavity are shaken out, effectively preventing the clogging of the shelter fish cavity. After the seaweed grows to a certain extent, the air intake chamber is inflated through the intake pipe, and the high-pressure gas pushes the piston to move outward, thereby increasing the overall volume of the seaweed culture medium, increasing the buoyancy of the seaweed culture medium, and driving the entire artificial reef upwards. Move, after the seaweed culture medium floats to the sea surface, harvest the seaweed manually. After the harvest is completed, open the air release valve to deflate, push the piston inward into the piston chamber and then close the air release valve, so that the seaweed culture medium sink into the sea. The setting of the fish inlet pipe provides more passages for fish schools to enter the shelter fish cavity, which is conducive to the diversion of fish schools. This kind of artificial fish reef structure has various functions. It can be used as a fish reef and cultivate seaweed. It has high economic benefits, and the seaweed can also be used as bait for fish schools, which can attract fish more. After the fish reef is put into use, it is not easy to be blocked. .

Preferably, the lower end of the fish reef base is provided with several support pipes communicating with the shelter fish cavity, and several anti-blocking holes are provided on the outer wall of the support pipes. When the fish reef substrate sinks to the seabed in the shallow sea area, the supporting pipe supports the fish reef substrate so that there is a certain distance between the fish reef substrate and the seabed, so as to avoid the phenomenon that the fish reef substrate is directly supported to the bottom of the sea and is blocked. The anti-blocking hole effectively avoids the phenomenon of blockage of the support pipe.

Preferably, the impacting balls are connected with limit ropes, the lower ends of the limit ropes are connected with pull rings, and the pull rings are all movably sleeved on the stay ropes. The limit rope plays a good role in limiting the impact ball, effectively preventing the impact ball from deviating from the fish reef substrate.

Several circular light holes are evenly distributed on the seaweed culture medium, and the light holes penetrate to the lower surface of the culture plate. It is a square reinforced concrete structure, and a row of fish inlet pipes is arranged on each side wall of the fish reef base. The light hole enables the seaweed on the seaweed culture substrate to be irradiated with enough sunlight, which is beneficial to the cultivation of the seaweed.

As a preference, the upper surface of the fish reef base is provided with a seaweed attachment plate, and the upper surface of the fish reef base is provided with a circle of "back"-shaped raised lines, the raised lines run through the seaweed attachment plate and the upper surface of the raised bar is flush with the surface of the seaweed attachment plate. Flat, there are four suspension rings, respectively connected on the four sides of the protruding strip. The seaweed attachment plate is conducive to the attachment culture of the seaweed dropped from the seaweed culture substrate, and these seaweed can provide bait and better shelter for the fish school at the base of the fish reef. The lifting ring is connected on the convex strip and the connection strength is good.

As a preference, a limit ring is provided in the piston cavity close to the outer surface of the seaweed culture medium, and a limit flange is provided on the outer wall of the piston.
