Problems solved by technology

But unfortunately, in the natural state at 39 degrees north latitude, the sea cucumber seedlings bred that year were only the size of mung bean grains before winter, and it was difficult to avoid and resist predators such as fish, shrimp, and crabs by direct bottom sowing (2000-5000 heads per catty) , the survival rate is less than 20%

Embodiment Construction

[0012] Utilize the mesh cage of common shellfish with a mesh size of 0.5-0.8 cm to process a round hole in the center of the cage partition. type cavity. Pass the bamboo poles or sealed plastic tubes with a diameter larger than the round hole in the middle of the cage through the round hole in the center of each cage partition in turn, and pull the cage to the longest state, the round hole in the middle of each cage partition It will use the elasticity of the plastic itself to automatically tighten the bamboo poles or plastic pipes to keep the cage in a propped state. Before winter, take out the net bag or net sheet with sea cucumber seedlings hanging from the cage, put it into a net bag whose mesh is only smaller than the sea cucumber seedlings, tie the mouth of the net bag tightly with a string and put it into the net cage Among them, it is advisable to install about 40 sea cucumber seedlings on each partition, and then put two sealed empty mineral water bottles or plastic ...

Abstract

The invention provides a sea cucumber youngling benthic ecosystem temporary aquaculture device. A shellfish temporary aquaculture meshed cage is supported by a bamboo pole or sealed plastic pipe; a meshed bag or meshed sheet where sea cucumber younglings hung is placed into a meshed bag with meshes smaller than those of the meshed bag of the sea cucumber younglings; the meshed bag and floaters are placed into the shellfish temporary aquaculture meshed cage, sandbags are connected to two ends of the meshed cage through connecting ropes, one end of the meshed cage is connected to a raft to form a device body through a hanging rope, the certain distance is maintained between the device body and the meshed cage when tidal bore is eliminated, the distance between the meshed bag and seabed is decreased when the flow speed of the tidal bore is large, more possibilities are provided to sand and mud for entering the meshed cage when the meshed cage gets close to the seabed, and adequate nutrients are clung to the meshed bag or meshed net for the sea cucumber younglings. The device has the advantages that the technology blanks of sea cucumber youngling marine ecosystem aquaculture and sea cucumber benthic ecosystem aquaculture can be filled, and a complete industry chain of sea cucumber ecological aquaculture is acquired.

Description

technical field [0001] The present invention relates to agricultural seawater floating raft net cage culture, which is a method of temporarily cultivating sea cucumber seedlings on the seabed for overwintering ecologically by using the raft bodies, net cages and net bags of existing shellfish cultured floating rafts through minor adjustments and changes. device. technical background [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 complet...
