Problems solved by technology

[0004] When the multiplied kelp population is restored to the seabed ecology, due to the limitations of traditional breeding methods, it can only be carried out by binding and fixing the kelp seedling rope to the artificial algae reef.
Using this method for ecological restoration, the algae proliferation area is limited by the size of the reef and the number of reefs, the restoration area is limited and the cost is high

Embodiment Construction

[0032] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0033] The wild sea-tangle artificial multiplication method of the present invention, specifically adopts following steps:

[0034] (1) Select a suitable wild kelp multiplication site:

[0035] Generally choose the edge of the damaged kelp population, or the reef seabed with smooth water flow and suitable light, and arrange the seabed fixing piles on the seabed in advance. The seabed fixing piles are arranged in a point-like matrix on the seabed, and buttonholes are arranged on the upper part of the pile body, which can be used for seabed fixing of the transplanted net.

[0036] (2) Prepare to plant kelp:

[0037] Wild kelp seedlings are generally collected in mid-to-late October when a large number of wild kelp matures in the north. Wild kelp with many leaf sporangia is selected as the seed kelp. Before using the seed kelp, it is nece...

Abstract

The invention provides an artificial reproduction method for wild kelps. The artificial reproduction method particularly includes the steps: (1) selecting a proper wild kelp reproduction site; (2) preparing parent kelps; (3) preparing spore fluid; (4) preparing a seedling collection box and a transplantation network; (5) collecting seedlings; (6) temporarily rearing the seedlings in a workshop; (7) temporarily rearing the seedlings on the sea; (8) separating the seedlings; (9) cultivating artificial seedlings; (10) transplanting the seedlings on a seabed. The seedlings are collected and intermediately cultured by the aid of the seedling collection box and the transplantation network in special design, rapid reproduction of artificial reproduction seedlings is realized, the influence of variable seabed terrains is overcome, and large-area seabed reproduction is realized.

Description

technical field [0001] The invention belongs to the field of marine ecological protection and restoration, and in particular relates to a method for artificially multiplying wild kelp. Background technique [0002] Kelp is a kind of brown algae species with economic value. After long-term artificial breeding, there are obvious differences in traits between artificially cultured kelp species and wild kelp species. Although the area of ​​cultured kelp is increasing, the natural distribution area of ​​wild kelp is showing a trend. decreasing trend. Wild kelp is usually fixed on reefs at a depth of 2-5 meters below the offshore tide line, often forming a large area of ​​seaweed beds, which can provide places for habitat, foraging, and spawning for benthic organisms and swimming organisms, so they have important ecological significance. However, in recent years, as the coastal environment has been destroyed by humans (such as artificial cofferdams, port projects, etc.), the ori...
