Problems solved by technology

At present, the artificial algae fields built by people are relatively simple and extensive, such as throwing stones, cement blocks or cement boards, etc., relying on seaweed to grow naturally on them
The disadvantage of this kind of artificial algae field is that the weight of raw materials used is high and the labor intensity is high; the sediment in the pond is easy to co

Embodiment 1

[0009] Example 1, first fill the cage 1 with oyster shells 2, use the oyster shells 2 to collect seaweed-Ulva pore spores, hang them on a raft frame and temporarily raise them for 2 months, and the seedlings developed from the ulva pore spores in After the oyster shell 2 grows firmly, be that the barbed wire 3 of 1.5cm with diameter 1.5mm, mesh is wrapped tight mesh cage 1, is fixed on the seabed with the cable 4 of diameter 3.5cm.

Embodiment 2

[0010] Embodiment 2, fill oyster shell 2 in mesh cage 1 earlier, and mesh cage 1 external use diameter is 1mm, and the wire mesh 3 that mesh is 1.0cm wraps tightly. Collect seaweed-kelp spores directly on a polyethylene rope with a diameter of 0.5cm, and hang them on a raft for temporary storage for 2 months. After the seedlings developed from the kelp spores grow firmly on the polyethylene rope, tie the polyethylene rope to the cage 1 outside, be fixed on the seabed with the cable 4 of diameter 4.0cm.

Embodiment 3

[0011] Embodiment 3, the oyster shells 2 are filled in the cage 1 in advance, and the outside of the cage 1 is wrapped tightly with a wire mesh 3 with a diameter of 2 mm and a mesh of 2.0 cm. Directly collect the autumn spore seedlings of seaweed-wakame on the net cage 1 wrapped with barbed wire 3, cultivate one month indoors, after the seedlings developed by the wakame spores grow firmly on the net cage 1, use the net cage 1 A cable 4 with a diameter of 1.0 cm is fixed to the seabed.

Abstract

The invention relates to an artificial sea-grass field which is characterized by comprising a net cage; the net cage is provided with a seashell; an iron mesh is wrapped on the net cage; a fixed cable is arranged outside the iron mesh. During construction, sea-grass seeds are introduced to the seashell or a PE rope and wound on the net cage; the cable is used to levelly lay the net cage and fix the net in the depth of the sea. The price of the construction materials used by the invention is low, the raw materials are easily available, the operation is convenient, and the depth of the prior sea which is not suitable for the sea-grass to grow is improved, so that the depth of the sea is suitable for the sea-grass to be attached and grow. In the construction method, large sea-grass seedlings are introduced artificially, so that the construction success rate of the sea-grass field is high. The artificial sea-grass field can effectively prevent the eutrophication of sea areas, improve the water quality and restore the ecological environment of the sea areas; meanwhile, the sea-grass itself is the bait of marine organisms and the place of activities and egg laying, which can improve the biological diversity index of the sea areas.

Description

technical field [0001] The invention relates to an artificial algae field and a construction method thereof. Background technique [0002] In recent years, the degree of eutrophication in the coastal waters has been serious, the ecological environment in the sea area has lost balance, and red tides have occurred frequently. In addition, overfishing has led to a decrease in the number and types of fish in coastal areas, and serious damage to fishery resources. Macroalgae are ecological restorers and stabilizers of the marine environment. However, in offshore and aquaculture sea areas, some substrate conditions are not suitable for the growth of large algae, which affects the feeding and spawning of marine organisms. In this case, artificially improving the substrate conditions of these sea areas, introducing macroalgae, constructing "artificial algae farms" and establishing a comprehensive ecological breeding system are problems that need to be solved urgently. [0003] In...
