Sea cucumber youngling meshed cage benthic ecosystem temporary aquaculture method

Abstract

The invention provides a sea cucumber youngling meshed cage benthic ecosystem temporary aquaculture method. A 'sea cucumber aquaculture meshed cage' is connected to a raft through a connecting rope, two to three protective rings are installed on the meshed cage to form a device body, the device body is sunk to the seabed, and the meshed cage can be closer to the seabed through the protective rings and can be prevented from damage due to direct friction between the meshed cage and the sand of the seabed; the device body performs horizontal reciprocating motions daily with the raft according to the change of tidal bore, the meshed cage is not prone to embed into the sand and mud, the sand and mud is possible to enter the meshed cage, sea cucumber younglings are capable of obtain food in the seabed in large area conveniently, and the sea cucumber youngling meshed cage benthic ecosystem temporary aquaculture is implemented. The method has the advantages that the technology blanks of sea cucumber youngling marine ecosystem aquaculture and sea cucumber benthic ecosystem aquaculture can be filled, the technological problem which people eager to solve and which is failed to solve before is solved, and a complete industry chain of sea cucumber ecological aquaculture is acquired.

Description

technical field [0001] The invention relates to an industrial chain of ecological temporary cultivation of fishery sea cucumber seedlings and sea cucumber ecological cultivation. Background technique [0002] For many years, the temporary cultivation of sea cucumber seedlings in my country has mainly been carried out in nursery rooms. The disadvantages are: the breeding density per unit of water is too high, and a large number of drugs are used to control diseases, resulting in drug residues in sea cucumber seedlings. In recent years, a "new technology for ecological cultivation of sea ginseng in net cages" is booming in Changhai County, Liaoning Province. In 2012, the local standard of Liaoning Province was promulgated. The popularization and application of this new technology has completely got rid of the dependence of sea cucumber seedlings on antibiotics. But unfortunately, in the natural state at 39 degrees north latitude, the sea cucumber seedlings bred in those years...

AI Technical Summary

Problems solved by technology

But unfortunately, in the natural state at 39 degrees north latitude, the sea cucumber seedlings bred in those years were only the size of mung bean grains before winter, and it was difficult to avoid predators such as fish, shrimp, and crabs by direct bottom sowing (2000-5000 heads per catty). It's better to find a shelter

But now farmers can only put them directly into the sea area where they are sown. At this time, the sea cucumber seedlings are too small to be put directly into the sea. Less than 20% of them can survive and grow into finished products.
