Problems solved by technology

[0005] After investigation, it was also found that seaweed tends to grow and reproduce in the reef layout that can form a suitable hydrodynamic force. Insufficient hydrodynamic force cannot wash the seaweed, which is not conducive to the long-term growth of seaweed, but too large hydrodynamic force is not conducive to the attachment of seaweed
The waves in the high tide zone are

Embodiment 1

[0034] Such as Figure 1-4 As shown, a sargassum multiplication algal reef system includes an algae multiplication reef 1 , a multiplication reef fixing plate 2 and a support plate 3 . The algae proliferation reef 1 is cylindrical, and the upper surface of the algae proliferation reef 1 is provided with an annular outer baffle 4 and an annular inner baffle 5, and the inside of the annular inner baffle 5 is a water storage area 16. Between the annular outer baffle 4 and the annular inner baffle 5 is the water storage area II 7 . The double-ring track-shaped design of the algae proliferation reef 1 enables the algae proliferation reef 1 to reach the maximum deposition area at the same height. The annular inner baffle 5 does not completely seal the water storage area 16, and two fractures 8 are provided on the annular inner baffle 5, and the two fractures 8 are symmetrically designed to facilitate the movement of the algae in the algae proliferation reef 1. The interior (that i...

Embodiment 2

[0039] A method for multiplying Sargassum, comprising the following steps:

[0040] (1) Place the algae proliferation reef after picking the seedlings in the high tide zone for temporary cultivation.

[0041] Because early sargassum seedlings are delicate and difficult to resist the scour of big waves, look for large reefs to form pond areas (depth should> 1m) in the high tide zone, use the algae proliferation reef of embodiment 1 to carry out sargassum seedlings, and then directly put them in high tide Bring the pond area for holding. The water power of the pond in the high tide zone is not strong, and it is not easy to damage the sargassum seedlings. At the same time, the algae proliferation reef is not easy to be carried away by the waves, and the large water body in the pond area can help resist strong changes in temperature.

[0042] If the high tide zone does not form a pond with suitable specifications or in the high tide zone of the silt bottom, utilize the algae prol...

Embodiment 3

[0047] Implementation site: rock bottom

[0048] Place the algae proliferation reef with Sargassum seedlings attached to them in a pond formed by reefs in the high tide zone, with a maximum depth of 1.1m after ebb tide, and measure the length of Sargassum seedlings after 2 months. The data are shown in the table 1.

[0049] Table 1. Temporary cultivation effect of Sargassum seedlings in the high tide zone pond area

[0050]

[0051] During the actual breeding process, it was found that Sargassum adhered more at the junction of the annular (inner and outer) baffles and the bottom of the water storage area (I, II). Therefore, the design of the inner and outer double-layer annular baffles was compared to only The single-layer design with circular outer baffle, on the basis of the same diameter, the double-layer design can provide more attachment area for sargassum.

[0052] Take out the temporarily raised algae proliferation reefs one by one from the pond, and fix them on ro...

Abstract

The invention discloses a Sargassum thunbergii proliferation reef system, comprising algal proliferation reefs, a proliferation reef fixing plate and a support plate. An outer circular retainer and aninner circular retainer are arranged on the upper surface of each algal proliferation reef; a water storage region I is arranged inside each inner circular retainer; a water storage region II is arranged between each outer circular retainer and the corresponding inner circular retainer; each inner circular retainer is provided with a plurality of fractures; the algal proliferation reefs are fixedto the upper surface of the proliferation reef fixing plate; the long sides of the proliferation reef fixing plate are parallel to the wave direction; the end of the proliferation reef fixing plate far away from waves is in direct contact with a beach; the end of the proliferation reef fixing plate close to waves is erected on the beach through the support plate, so that the algal proliferation reefs on the proliferation reef fixing plate are kept horizontal. The Sargassum thunbergii proliferation reef system is simple in technicality and low in preparation cost; application of the Sargassumthunbergii proliferation reef system shows that the Sargassum thunbergii proliferation reef system has large deposition area, the surface of algae is clean and free of attachment by Colpomenia sinuosa, Ectocarpus confervoides and the like, and the alga is complete and free of animal bites.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a sargassum multiplication algae reef system and an application method thereof. Background technique [0002] Sargassum thunbergii belongs to Phaeophyta, Enculiae, Fucusaceae, Sargassumaceae, Sargassum genus. It is mainly distributed in the intertidal zone and is a dominant species. It is distributed from the Liaodong Peninsula in the north to the Leizhou Peninsula in the south. The seaweed bed is a place where large algae (brown algae) on the bottom of the hard phase seabed flourish and prosper in the subtidal zone of the mid- and high-latitude sea area and in the shallow water area of ​​the subtidal zone for a few meters. Sargassum is an important tool algae for seaweed bed restoration. [0003] The intertidal zone refers to the coast between the average highest tide level and the lowest tide level, that is, the range from where the sea water is submerged when...
