The present invention relates to a shell larvae production tank, and more particularly to a shell larvae production tank for producing a seed shell at a high density per unit tank area.

In general, various methods of farming shellfish such as oysters, abalone, shellfish, scallops, clams, lilies, and clams are widely practiced. Species of domestic fish and shellfish rely on natural species, but in recent years, they have been changed to produce seed from land tanks.

However, in recent years, due to industrial development, the supply of natural seed is unstable due to coastal marine environmental pollution, and thus the resource of seed seed is insufficient.

Thus, in order to overcome the shortcomings of the production method of shellfish shellfish using coastal or near sea, ie, seawater, a shellfish shellfish shelling method has been proposed.

In this way, the abalone farming method is disclosed in Republic of Korea Patent Publication No. 10-1997-0032373 (aquaculture method of abalone seedlings) in the shellfish farming in particular.

That is, the conventional abalone seedling farming method is a natural process by collecting the healthy mother's hair, the process of stimulating the selected female and male of the collected mother's hair and drying the stimulation, and by continuously exchanging the seawater filtered by ultraviolet sterilizer Spawning process to induce spawning, fertilization process to fertilize spawned and estimated ovaries and spermatozoa, positive process to screen and discriminate normally fertilized larvae, and to grow grown seedlings in aquaculture tank Through the aquaculture process, they show how to grow healthy abalone seedlings.

The conventional tank for farming shellfish of the conventional shellfish consists of rectangular, circular, square, etc. with the inner side as a rectangular parallelepiped, and the wall surface is formed with cement material.

In addition, since the wall surface is generally vertical, the larvae of the shellfish that grew and floated in the initial water gradually grow, and when the size increases, the shell surface sinks to the bottom surface under the weight of the shellfish itself.

As the shell larvae sinking to the bottom gradually increase, when a large number of shell larvae accumulate on the floor, the feeding activity of the shell larvae that are stacked and located below is disturbed, and thus the metamorphosis is not performed in a timely manner. Shell larvae die.

As a result of this phenomenon, the survival rate for producing shell larvae is lowered, which causes a problem of inhibiting the productivity of shellfish.

That is, in the conventional marine shellfish culture tank as described above, there is a problem in that the productivity of shellfish is lowered due to the production of seed shells per 1 ml, and the cost is relatively increased.
