Fish and shellfish farming is carried out for the purpose of feeding. The ecology of growth related to the proliferation of fish and shellfish is unconventional, and it is difficult to establish a standard theory. Normally, after spawning, hatched larvae transition to juveniles and gradually grow. During the process, they ingest plankton, diatoms, etc. as food. In the past, when breeding fish and shellfish in artificial hatcheries or farms, corrugated synthetic resin plates made of vinyl chloride were immersed in seawater and placed in rows as steering plates for culturing fish and shellfish larvae. A method of growing diatoms, etc. on the surface of the board has been used.However, the synthetic resin board made of hard vinyl chloride has poor resistance to seawater, so it has the disadvantage that it gradually weathers or corrodes and breaks when used for a long period of time. was there.

It can withstand long-term use, and the growth of diatoms, green algae, brown algae, etc. is carried out well. The purpose is to provide samurai with Shi4chi cultured river algae plates for seafood used in hatcheries, aquaculture farms, etc.

ある。That is, the present invention is a thin plate for fish and shellfish culture, which is characterized by comprising a glass substrate plate having an uneven cross section.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.
本発明に係わるガラス質基板は力１（害、無臭で幼生に
対する有害成分の無溶出のガラス質の材質のものであれ
はいかなるものを用いてもよい。As the glass substrate according to the present invention, any glass material may be used as long as it is harmless, odorless, and does not elute harmful components to larvae.
ガラス質基板の埋さは２〜５ Ｑ ｍｍ か好ましく
、２ ｍｍ 未満では所望の強度に欠け、５３ｍｍ
をこえると必要以１−．の厚さになり不経済である。The depth of the glass substrate is preferably 2 to 5 Q mm; if it is less than 2 mm, it lacks the desired strength;
If it exceeds 1-. It becomes thick and uneconomical.
又、ガラス質基板は上記厚さの範囲内において使用され

1"5, and a glass substrate having a large number of four-part or insect-eaten holes 4 on the surface of the glass substrate as shown in FIG. A glass substrate with such an uneven cross section can be easily manufactured by conventional processing methods such as glass pressing or by industrially etching the surface of the glass substrate.

促進される。1) Since the steering board for culturing fish and shellfish larvae of the present invention is formed from a glass substrate with an uneven cross section, it does not elute alkaline substances and can be used by being immersed in seawater. In this case, the transmitted Taichiyu light rays are diffusely reflected on the uneven surface of the glass substrate and promote photosynthesis, which is optimal for the growth of diatoms, green algae, brown algae, etc., and their reproduction is significantly promoted.
２）１亀水に耐性のあるガラス質基板で形成されている
ので７）σ水で腐蝕されることなく長期間使用しても破
壊されない。2) Since it is made of a glass substrate that is resistant to water, it will not be destroyed even after long-term use without being corroded by σ water.
３）ガラス質基板の断面が凹凸に形成されているので、
表面積が大きくなり珪藻、緑藻等の付着附か増加すると
共に四部又は穴の中に幼生が沈着生育することかできる
ので魚介類の養殖に有利である。3) Since the glass substrate has an uneven cross section,
It is advantageous for fish and shellfish cultivation because the surface area becomes larger, which increases the adhesion of diatoms, green algae, etc., and allows larvae to settle and grow in the four parts or holes.
４）長ｋｌ１間使用していると表向に汚れや有節石灰質
が堆積（＝Ｊ着するか、ガラス質基板の表ｍ１は平滑で

After 20 days of cooling and circulating with a pump, the glass substrate was examined and found that there were many circular diatoms on the surface with an average Q of 5 mm and a depth of 12 mm. A test was conducted in the same manner as in Example 1 using a glass substrate with a hole of 5 lcm (vertical) x 50 (horizontal) f:m x 2Q mm thick (thickness). The diatoms and green algae grew to a thickness of 1.
