Embodiment 1

[0032] 1. Attaching seedlings: attaching kelp of the genus Laminaria to the cultivation grid, seaweed cultivation curtain and seaweed cultivation rope by clipping seedlings;

[0033] 2. Construct a fixed-shaped seaweed bed: four positioning piles are built according to the rectangular or square structure, and the positioning piles are equipped with hard frame pile cables, and the floating balls are tied on the positioning piles as a sign; four equal-length PPR cold water pipes and Elbows of the same diameter are welded to the rigid frame 3 and the stereotyped frame 11 of the same shape and size by hot melting; the top surface of the rigid frame 3 is equipped with a breeding grid, and the four sides are seaweed cultivation curtains; the four corners of the stereotyped frame 11 are suspended Gravity falling stone 10, the four sides are tied to the seaweed cultivation curtain and then submerged in the water, and then the other side of the seaweed cultivation curtain is tied to the...

Embodiment 2

[0037] The construction method is the same as that in Example 1, except that in step 1, Sargassum sargassum of the genus Sargassum is attached to the cultivation grid, the seaweed cultivation curtain and the seaweed cultivation seedling rope; two months after the construction of the seaweed bed, it was found that , A large number of attached fish eggs were found on seaweed cultivation curtains and seaweed cultivation seedling ropes, and the number was 15 times that on artificial fishing reefs.

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 spore-attached seedlings; two months after the construction of the seaweed bed, it was found that , A large number of attached fish eggs were found on seaweed cultivation curtains and seaweed cultivation seedling ropes, and the number was 18 times that on artificial fishing reefs.

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 that of tropical rainforests, and are an important part of marine primary productivity. Shallow seaweed beds have the function of biological protection and can be used as bait, spawning, shelter and habitat for other marine organisms. Seaweed farms can absorb 25% of global carbon emissions, not only can improve the sea environment, but also become an important carbon sink element, and have an important function of biological remediation. [0003] Seaweed is the main body of the coastal water ecosystem of islands, but the shallow sea, especially the coastal waters, is a fragile ecosystem; with the development and utilization of marine engineering, the marine ...
