High-efficiency three-dimensional ecological cultivation system for buried shellfish

Abstract

The invention discloses an efficient three-dimensional ecological culture system for buried shellfish, which comprises a culture box, an aeration oxygenation tank and a feed culture tank; the culturebox is divided into a plurality of tiers of parallel culture unit boxes, a support plate is arranged at the bottom end of each tier of culture unit box, and a pollution collecting and discharging chamber with a pollution collecting and discharging pipe is arranged below the lowest tier of culture unit box; a water inlet dividing pipe is arranged above each tier of cultivation unit box, two ends ofeach water inlet dividing pipe are vertically communicated with a water inlet pipe and a water outlet pipe, the water inlet pipes or the water outlet pipes of two adjacent tiers of cultivation unit boxes are in sliding sealing fit in a sleeved mode, the water inlet pipes and the water outlet pipes are respectively communicated with the aeration oxygenation tank, and the feed culture tank is communicated with the aeration oxygenation tank through an algae suction pipe with a suction pump. The system simulates a natural state, the feed culture system and a circulating water culture system are organically combined, the problems of single feed for shellfish culture, labor consumption for feed culture and the like are solved, the experiment time is utilized more efficiently, and unnecessary consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of shellfish ecological breeding, in particular to an efficient three-dimensional ecological breeding system for buried shellfish. Background technique [0002] Marine benthic shellfish is an important ecological type of marine organisms. In coastal areas, tidal flats and shallow sea areas, the main cultured species include bivalve and gastropoda. Such as green clams, Meretrix meretrix, four-cornered clams, mud snails, Xishi tongue, etc. The traditional farming mode is tidal flat farming, and there are also some pond farming, usually mixed with fish and shrimp. Its production methods are almost entirely supported by open farming and animal husbandry. With changes in the marine environment and stricter food safety requirements, the contradiction between the deterioration of the sea environment, the expansion of breeding capacity, and the quality of products is becoming more and more troublesome. With the de...

Problems solved by technology

[0003] There have been reports on relevant shellfish recirculating culture systems in the prior art, such as Jiangsu Ocean University Shellfish Research Office has an indoor circulating water shellfish temporary culture system covering an area of ​​100 square meters, but there are deficiencies in this system when used: One is that it occupies a large area and the efficiency per unit area is low; the other is that the bait cultivation system is separated from the breeding system, which consumes a lot of manpower in bait cultivation; the third is that it is difficult to clean and discharge sewage
