Problems solved by technology

[0003] In order to overcome the shortcomings of the catapult method and solve the problem of lack of special bottom sowing and breeding facilities for shallow sea cucumbers and abalones, the present invention provides a multi-layer combined sea treasure reef suitable for shallow seabed sowing and breeding. The facility can greatly increase the breeding The habitat space of sea cucumbers and abalones, and provide a wide growth surface for macroalgae, thus providing sufficient bait supply for sea cucumbers and abalones

Embodiment 1

[0026] Example 1: Construction of artificial algae bed and restoration of fishery resources

[0027] In this embodiment, the three-layer cement board and two cement columns of the reef are made respectively. After the production is completed, they are assembled and formed. In the sea area around Pingdao, Haizhou Bay, Rizhao, a flat sea area with a water depth of less than 10m and good transparency is selected. Cranes are used for large-scale release, and the distance between reefs is 3-5m. After a maturing period of about one year, a relatively luxuriant large-scale algae community formed on the surface of the reef, forming a certain scale of artificial algal beds, as shown in Figure 3 (a)-(b), which attracted many fish (the main species is black squid , six-line fish) habitat.

Embodiment 2

[0028] Embodiment two: Apostichopus japonicus bottom sowing multiplication

[0029] In this example, the three-layer cement board and two cement columns of the reef are made respectively. After the production is completed, they are assembled and formed. The sea area around Pingdao, Rizhao Haizhou Bay is flat, the water depth is less than 10m, the transparency is good, and it is suitable for sea cucumber bottom sowing. For the proliferating sandy and muddy seabed sea area, large-scale release is carried out with the help of ship-borne cranes, and the distance between reefs is 3-5m. After a maturing period of about one year, a relatively lush macroalgae community is formed on the surface of the reef.

[0030] About 30g of japonicus seedlings were sown at the bottom of the adjacent area of ​​the reef. After one and a half years of growth, an average of 5 japonicus perched on each reef in the reef area, and the distribution density of japonicus within 5m around the reef was about ...

Abstract

The invention relates an artificial reef body suitable for aquaculture of the seafood, such as abalone and sea cucumber and the like, in particular to a multilayer combined type sea reef suitable for shallow seabed sowing aquaculture, which solves the problem of the lack of facilities dedicated for shallow seabed sowing aquaculture of abalone and sea cucumber. The sea reef body comprises a vertical column and at least two plates, wherein, the two plates are sheathed on the vertical column in a layering manner, and each layer of plate is sheathed with the vertical column through a rectangular hole; the top part of the vertical column is provided with a lifting pull ring. The facility is easily manufactured, and can provide three-dimensional perch space and shelter for aquaculture of the abalone and the sea cucumber; the reef body has wide and rough surface area for adhesion of various macrophytic algae and benthic microalgae, and is easy to form algal bed to provide adequate bait for the aquaculture of seafood; the reef body has moderate spacing, which is easy for batch harvest of aquaculture products. Aquaculture production of the seafood can be carried out in the sea region of shallow sand and mud substrate where lack of reef and is not suitable for seabed sowing aquaculture of the abalone and the sea cucumber by applying the facility, and the facility is beneficial for developing seafood aquaculture area and increases yield of the products.

Description

Technical field: [0001] The invention relates to an artificial reef body suitable for multi-layer breeding of sea treasures such as abalone and sea cucumber, in particular to a multi-layer combined sea treasure reef suitable for sowing and multi-culture of shallow seabed. Background technique: [0002] Sea cucumbers and abalones are important species for bottom sowing and breeding of shallow sea sea treasures in my country. According to the living habits of sea cucumbers and abalones, in addition to choosing naturally distributed rocky reefs in shallow seabed breeding areas, most of them establish breeding areas by throwing rocks on sandy and muddy seabeds. Although the stone catapult method is easy to operate, its disadvantages are that it is not specific, and the space utilization rate is low, and the habitat space provided for aquaculture organisms is relatively limited; the surface area of ​​the stones thrown in for the growth of macroalgae is small, and it is difficult ...
