Description

[0002] Cultivating Apparatus of Bivalves for the Integrated Culture in Embankment Pond [

The present invention relates to a device for culturing shellfish such as oysters and mussels in a festival farm or a cage farm which is not greatly affected by waves, and more particularly to a device for culturing shellfish such as oysters and mussels, The float height of the float can be stably controlled through the process of selectively supplying or discharging air or water, and the exposure and sedimentation of the shellfish are repeated periodically, thereby improving the survival rate of the cultured shellfish. The present invention relates to a shellfish culture apparatus for effectively removing various attachments of a net.

A festival farm is a method of cultivating mainly fish and shrimp by circulating the water by stacking the banks on the seashore, and the festival farm is used for continuous feeding of fish and shrimp culture, And the biomass of phytoplankton which feeds on shellfish is very high. While high density phytoplankton has advantages such as water quality and stabilization of fish, excessive attention is required for water quality management because there are always shortcomings such as oxygen depletion and rapid water quality at night. Therefore, it is possible to suppress the occurrence of excessive phytoplankton by introducing shellfish feeding on phytoplankton, and at the same time, there is an advantage that promotion of the growth of shellfish can be promoted. Therefore, fishes and shrimps, It is anticipated that when mixed and cultured, water quality changes can be controlled.

Shellfish living in tidal flats exposed in seawater, such as oysters and mussels, are cultivated in the tidal flat during the cultivation process, so that they are immersed in sea water during high tide and exposed to the sea surface during low tide. Produces high quality shellfish of high quality. On the other hand, in the case of oysters, there is also a method of hatching a rope, which is woven with a rope attached with a young spatula at regular intervals, in a seawater, and this type of method continuously grows because it takes food in seawater But it has a disadvantage in that the mortality is relatively higher than that of the oysters cultured by exposure, and the strength and nutrients of meat are less.

On the other hand, in Korea, in order to improve the survival rate of oysters, shellfish attached to spatulas were suspended in the tidal zone for a certain period of time. After application of the spat harvesting method repeatedly exposed and immersed, .

In recent years, artificially cultivated seedlings produced directly from seeds are produced. This method of cultivation is a cause of decline in fisheries productivity by the abolition of juvenile litter that has not adapted to the marine environment. In particular, the method of exposure through the exposure and immersion of the spatula can be effectively performed by adhering to shells and the like in the case of adherent shellfish, Effective intermediate breeding methods or methods for breeding have not been developed.

Therefore, it is possible to improve the survival rate of full-scale aquaculture by effectively exposing and sedimenting the juvenile stage of the shellfish in a festival-type aquaculture that is rich in food organisms and is not greatly affected by waves In addition, it is possible to control the density of phytoplankton, which is a feeding organism, in the festival farm, so that the water environment of shrimp and fish culturing can be maintained in proper ecology.

On the other hand, as a conventional technique for presenting an oyster aquaculture apparatus of a shellfish culture apparatus, Patent No. 10-1419133 discloses that as a traction rope is pulled, a plurality of positive mesh connecting ropes are caught by each of a plurality of engaging members, To expose them to the surface of the water periodically.

The valve 410 is adjusted. The water in the floating structure 110 is discharged to the outside through the water flow path 422 by the air pressure. Through this process, the overall specific gravity of the floating structure 110 becomes small, and it rises above the water surface.

When the floating structure 110 is moved from the floating state to the water immersion state, water is allowed to flow through the floating structure 110 through the water flow channel 422 while the air vent opening 120 is opened. The check valve 410 is adjusted so as to be supplied into the check valve 410. [ In the above process, the air in the floating structure 110 is discharged to the outside through the air vent opening 120. Through this process, the overall specific gravity of the floating structure 110 increases and falls to the bottom of the water surface.

As described above, the shellfish culture apparatus according to the present invention can stably control the height of the float in the water by selectively supplying or discharging air or water into the hollow fluid having the shellfish culture net installed therein do.
