Description

Device for rearing abalone

The present invention relates to an abalone farm, and more particularly, to an abalone farm where seawater can flow smoothly into a cage and uniform food can be supplied to abalone in a cage.

In Korea, fishing is being developed because the three sides are in contact with the sea. As the income level increases, the consumption of aquatic products also largely shifts into a form of feeding and breeding in the form of catching fish. In this aquaculture industry, .

In the cultivation of abalone, conventionally, the abalone seeds have been radiated into the sea and after harvesting the abalone that has been grown through water work for many years, or the abalone cultivar in the form of concrete is installed in the sea, However, both the former and the latter have a disadvantage in that they can not be cultivated in large quantities or are intensively cultivated and harvested. Since abalone is left in the sea, abalone disappears due to natural enemies in the aquaculture process, This makes it difficult to harvest and expect even productivity.

As a result, in the cultivation of abalone, a farm where a mesh is installed to cover an abalone such as an abalone aquaculture apparatus disclosed in Korean Utility Model Publication No. 20-1991-0002901 is mainly used. Generally, the mesh is manufactured using a soft material having a small weight and easy to install.

However, since the conventional abalone farm has a structure in which a plurality of cages are arranged at the same depth, the cage located at the rear of the cage is not smoothly infiltrated into the interior by the cage located at the front side, In addition, the conventional abalone farm cage has a disadvantage in that it is difficult to uniformly feed the abalone in the cage because the feed is concentrated at one side of the cage due to the seawater when the feed is put into the abalone farm cage.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a food hanger unit in which adjacent cages are arranged at different depths and a feeding hanger unit The purpose is to provide a farm.

In order to accomplish the above object, the abalone farming system according to the present invention comprises a floating structure suspended on the sea surface, a suspended structure suspended on the floating structure by the connecting unit, located below the sea surface, And a food hanger unit installed inside the cage and capable of mounting the food to prevent the food of the abalone put in the habitat from flowing due to currents.

The cages adjacent to each other are suspended in the floating structure so as to be spaced apart from each other in the vertical direction so that seawater can be easily introduced into the respective format spaces.

At this time, the floating structure may include a main rope extending in the longitudinal direction, and a fixing portion fixed to the main rope so as to be spaced apart from each other along the longitudinal direction to provide a predetermined buoyancy.

Wherein the food hatching unit comprises: a support rod extending downwardly to the stationary rod at a position spaced apart from the extension rod along the longitudinal direction of the stationary rod; a second hollow fixed to the lower end of the support rod, And may further comprise a support body provided.

The food hatching unit is coupled to the coupling rod located on the lower side with respect to the main tube and includes a first sub-tube having a first through hole to allow the coupling rod to pass therethrough, and a second sub tube extending upward from the first sub- And a first fixing rod whose upper end is fixed to the main tube so as to prevent the main tube from rotating due to current flow.
