Problems solved by technology

[0004] At present, the domestic and foreign methods of constructing shallow seaweed beds mainly include stone-throwing method, reef sweeping method, artificial fishing reef method, blasting rock reef method and algae seeding method. It is difficult to form a natural ecosystem with a single substrate and a single algae species

Embodiment 1

[0032] 1. Attached seedlings: attach the kelp of the kelp genus by clamping seedlings on the breeding grid, seaweed breeding curtain and seaweed breeding seedling rope;

[0033] 2. Construct a seaweed bed with a fixed shape: drive four positioning piles according to a rectangular or square structure, set up hard frame pile cables on the positioning piles, and tie floating balls on the positioning piles as a sign; use four equal-length PPR cold water pipes and The elbows of the same diameter are welded by hot-melt to the rigid frame 3 and the stereotyped frame 11 of the same shape and size; the top surface of the hard frame 3 is equipped with a culture grid, and the four sides are equipped with seaweed culture curtains; the stereotyped frame 11 is suspended at four corners Gravity rock drop 10, tether the seaweed culture curtain on all four sides and then sink into the water, then tie the other side of the seaweed culture curtain to the four sides of the rigid frame 3, and place th...

Embodiment 2

[0037] The construction method is the same as in Example 1, except that in step 1, the cultivation grid, the seaweed cultivation curtain and the seaweed cultivation seedling rope are attached to the Sargassum genus by clamping seedlings; the seaweed bed was constructed 2 months after the investigation found , A large number of attached fish eggs were found in the seaweed culture curtain and the seaweed culture seedling rope, the number is 15 times that on the artificial reef.

Embodiment 3

[0039] The construction method is the same as in Example 1, except that in step 1, the cultivation grid, the seaweed cultivation curtain, and the seaweed cultivation seedling rope are attached to the laver of the genus Porphyra by means of spores attached to the seedlings; the seaweed bed is constructed 2 months after investigation and found , A large number of attached fish eggs were found in the seaweed culture curtain and the seaweed culture seedling rope, the number is 18 times that on the artificial reef.

Abstract

The invention discloses a shallow sea three-dimensional floating algal bed device and a construction method of the shallow sea three-dimensional floating algal bed device. An algal bed comprises soft-chain structures, a rigid framework structure and a shape-setting framework. The rigid framework structure comprises rigid frameworks, rigid framework tying ropes and rigid framework pile cables, wherein cultivation meshes are arranged on the top surfaces of the rigid frameworks, drooping alga cultivation curtains are tied to the side faces of the rigid frameworks, the lower ends of the alga cultivation curtains are connected with the shape-setting framework located underwater, and the rigid frameworks are connected with one another through the rigid framework tying ropes where floating balls are hung; the soft-chain structures are arranged around the connected rigid frameworks, wherein the soft-chain structures comprise rope cables, floating balls, tying ropes and alga cultivation seedling ropes; the drooping alga cultivation seedling ropes are fixed to the rope cables, and the two ends of each rope cable are connected with shape-setting piles through the corresponding pile cables. According to the shallow sea three-dimensional floating algal bed device and the construction method of the shallow sea three-dimensional floating algal bed, operation is simple, the input is low, the yield is high, the important functions of ecological reconstruction and ecological remediation are achieved, the fish gathering effect in ecological cultivation is good, and the economic benefit, the social benefit and the ecological benefit are remarkable.

Description

Technical field [0001] The invention relates to an algae bed device, in particular to a shallow sea three-dimensional floating algae bed device and a construction method thereof. Background technique [0002] Shallow seaweed beds are an important part of marine pastures, which can produce primary productivity similar to tropical rain forests, and are an important part of marine primary productivity. The shallow seaweed bed has the function of biological protection, and can be used as bait, spawning, shelter and habitat for other marine life. Seaweed farms can absorb 25% of global carbon emissions, not only can improve the marine environment, but also become an important carbon sink element, with important functions of biological remediation and restoration. [0003] Seaweed is the main body of the ecosystem in the coastal waters of islands. However, the shallow sea, especially the coastal waters, is a fragile ecosystem. With the development and utilization of marine engineering, t...
