Factorized totally-closed circulating aquaculture system of sea cucumbers

Abstract

The invention relates to a factorized totally-closed circulating aquaculture system of sea cucumbers, belonging to the technical field of aquaculture. The factorized totally-closed circulating aquaculture system comprises a special culture pond and a water treatment system; the special culture pond is a circular bead pond of which the bottom is shaped as a pan bottom, a water outlet is formed in the lowest position of the center of the special culture pond, and three to five circles of porous bottom flushing pipes are horizontally paved at the bottom of the pond; the water treatment system comprises a slow flow settling pond, a pump pond, a water lifting pump, a protein foam separator, a first-stage pollution cut biopurification pond, a second-stage degassing biopurification pond, a steam water convection oxygenation pond and a pipeline type ultraviolet sterilizer. The culture system suitable for factorized totally-closed circulating aquaculture is designed according to the biological characteristics of sea cucumbers and an aquaculture water circulation utilization technology; the daily supplement of new water is less than 5 percent during culture by using the system disclosed by the invention. Compared with a traditional water change or running water culture method, the system disclosed by the invention has the advantages that the water saving amount reaches over 95 percent; more importantly, the temperature control energy consumption in the culture process is greatly reduced and the energy is saved by over 70 percent.

Description

Technical field: [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a sea cucumber industrialized fully enclosed circulating aquaculture system. Background technique: [0002] Sea cucumber (Apostichopus japonicus), also known as sea cucumber, belongs to Echinodermata (Echinodermata) and Holothurioider (Holothurioider) in taxonomy. It is distributed in the intertidal zone of all oceans in the world to the sea area with a depth of 10,000 meters. It is a sediment-feeding marine animal. Sea cucumber has high nutritional and medicinal value, and is a high-end nutritional product that our people love very much. In recent years, with the growth of market consumption demand, the sea cucumber breeding industry has flourished, with an annual output value of more than 20 billion yuan. industry with the highest output value. [0003] Sea cucumber farming is mainly divided into near-shore bottom-seeding culture, intertidal zone cofferdam cul...

AI Technical Summary

Problems solved by technology

[0003] Sea cucumber farming is mainly divided into near-shore bottom-seeding culture, intertidal zone cofferdam culture, pond ecological culture and indoor factory high-density culture; due to factors such as industry, tourism, shipping industry, urban development and near-shore marine environment pollution Influenced by bottom-sowing farming near the shore, cofferdam farming in the intertidal zone, and ecological pond farming are showing a trend of shrinking, and indoor factory farming has the advantages of controllable farming environment, high breeding density, and short growth cycle, and the scale of farming is constantly expanding. However, the current factory farming mainly adopts temperature control and water exchange farming. The breeding process consumes a lot of energy and water, and requires regular pouring and flushing of the attachment base. The labor cost is very high, and a large amount of external drainage will easily lead to Seawater pollution and disease outbreaks and epidemics in the area have a high risk of breeding, and it does not meet the national requirements for energy conservation, environmental protection, and the development of a circular water economy.
