Multi-layer combined type stereoscopic holothurian culture adhesion substrate and combination method thereof

Abstract

The invention relates to a multi-layer combined type stereoscopic holothurian culture adhesion substrate and a combination method of the multi-layer combined type stereoscopic holothurian culture adhesion substrate, and belongs to the field of aquaculture devices. The multi-layer combined type stereoscopic holothurian culture adhesion substrate is composed of two rib frame structures with multi-layer crossarms and corrugated plates, each rib frame structure is a left and right symmetric structure composed of a main frame in the vertical direction and the crossarms perpendicular to the main frame, and the junction positions of the main frame and the crossarms are melted to be integrated structures. The two rib frame structures are embedded to form a reverse V-shaped structure, and the corrugated plates are hasped on the crossarms of the rib frame structures. The multi-layer combined type stereoscopic holothurian culture adhesion substrate can be combined quickly according to needs, after the combination, culture inhabiting faces are formed between all the corrugated plates, holothurian inhabiting is facilitated, and living space of holothurian is increased. The multi-layer combined type stereoscopic holothurian culture adhesion substrate and the combination method have the advantages of being easy and convenient to operate, seawater corrosion resistant, good in water permeability, large in surface area, good in shielding and capable of being used continuously, sewage is not prone to deposit, many shelter spaces are arranged, organic matter deposition is easy, mature holothurian recapture is facilitated, meanwhile, the culture density can be increased, and diseases are prevented from happening.

Description

technical field [0001] The invention belongs to the field of aquaculture devices, and in particular relates to a multi-layer combined three-dimensional sea cucumber culture attachment base and a combination method thereof. Background technique [0002] Stepping into the 21st century, with the rapid development of the national economy and the great improvement of living standards, domestic marine treasures, especially sea cucumber breeding, have developed rapidly. As of 2012, my country's sea cucumber breeding area has reached more than 100,000 hectares, with an annual output of 170,000 tons of fresh ginseng, and an economic benefit of about 30 billion yuan. The breeding methods include pond culture, cofferdam culture, factory culture, hanging cage culture, net cage culture, caisson culture and so on. In natural sea areas, sea cucumbers generally inhabit rocky reefs under the intertidal zone or the joints between rocks and mudflats, especially in the quieter backflow of the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the most commonly used artificial attachment bases for sea cucumber cultivation are stones, tiles, porous bricks, etc. The above materials have disadvantages such as inconvenient operation, high labor intensity, and unfavorable harvesting of finished ginseng in the process of building ginseng reefs. Ginseng reefs also have shortcomings such as small surface specific area, low ginseng density, and poor water flow exchange during the cultivation process, and there are disadvantages such as difficult placement and high labor costs during the pond cleaning process during the idle period of cultivation

The traditional net cage attachment base cannot block sunlight, and the surface area is small, which is not conducive to the deposition of organic matter and the enrichment and growth of single-celled algae, and the survival rate and yield of culture are low
