Sargassum thunbergii proliferation reef system and application method thereof

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...

AI Technical Summary

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 smaller, which is more conducive to the establishment of seaweed seedlings. However, due to the lack of hydrodynamic force in the high tide zone, the time is too long, and some seaweed will be entangled by water clouds and eventually rot.

The hydrodynamic force in the low tide zone is strong, which can scour the fixed seaweed, and the growth cycle of the fixed seaweed is longer
