【発明の詳細な説明】
（産業上の利用分野）
本発明は、栽培漁業に用いられる魚礁に・関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fish reef used in cultivation and fishing.
（従来の技術）
近年わが国の漁業は、世界各国の２００カイリ規制導入
により、従来の遠洋にて捕獲する漁業から近海にて育て
る漁業への転換を余儀なくされている。(Prior Art) In recent years, due to the introduction of 200 nautical mile regulations in countries around the world, Japan's fishing industry has been forced to switch from the conventional fishing industry in which fish are caught in the distant sea to fishing in nearby waters.
このような状況にあって、古くより知られている沈没船
の周囲に魚が多く集まるという事実をもとに、コンクリ
ート製構造物、いわゆるコンクリート魚礁を海中に沈め
、集まった魚を捕獲する方法が試みられてきた。Under these circumstances, based on the fact that many fish gather around sunken ships, which has been known for a long time, a method was developed to sink a concrete structure, a so-called concrete fish reef, into the sea and capture the fish that gathered. has been attempted.
さらに最近では、魚を集めるあるいは増やす効果が大き
いといわれる鉄鋼製魚礁、例えば特開昭５５−７７８４

が増殖するためと考えられている。Furthermore, recently, steel reefs, which are said to have a great effect on attracting or increasing fish, have been developed, such as JP-A-55-7784.
Japanese Patent Publication No. 0, Japanese Patent Publication No. 62-20162, etc. have been proposed as a concrete reef with an iron compound coated on its surface. These effects are thought to be due to the fact that iron or iron compounds are oxidized in seawater to form fine iron oxides, which further produce iron ions through the action of ultraviolet light, which causes phytoplankton to proliferate.
（発明が解決しようとする課Ｒ）
しかしながら上記の魚礁は、魚を集める効果が小さいこ

が多々あった。(Problem R to be solved by the invention) However, the above-mentioned fish reefs have problems such as having a small effect on attracting fish, being time-consuming, and the manufacturing cost of fish reefs being high. There were many difficulties.

Weight%, FeO: 20-60% by weight, FezOz:
This is an iron oxide composite concrete fish reef made by mixing cement with a mixture of metallic iron and iron oxide consisting of 10 to 50% by weight, and molding it into a structure.Also, by using cement containing a foaming agent, the surface is made porous. and even P
We propose a fish reef made of iron oxide composite concrete containing one or more of , N, Si, F, C1, Br, and I, and provide a fish reef that has an excellent effect of attracting fish at a low cost.
（作 用） 以下本発明を作用とともに詳細に説明する。(for production) The present invention will be explained in detail below along with its operation.
本発明において、魚礁に金属鉄及び酸化鉄を複合せしめ
る理由は、海中にて微粒鉄酸化物が紫外線による作用の
ため鉄イオンとなり、この鉄イオンが植物プランクトン
を増殖させ、その結果植物プランクトンを餌とする海藻
が増殖し、また魚が集まるという事実（週刊「北海水産
」昭和６３年２月２９日版社説）にもとすくものである
。In the present invention, the reason why metallic iron and iron oxide are combined in fish reefs is that in the sea, fine iron oxides become iron ions due to the action of ultraviolet rays, and these iron ions cause phytoplankton to multiply, and as a result, feed on phytoplankton. The fact that seaweed grows and attracts fish (editorial in Weekly Hokkai Suisan, February 29, 1988) is also surprising.
このため鉄鋼製魚礁は、鉄が海中の酸素により酸化され
、酸化鉄（ＦｅｚＯｚ）を生成するため上記作用がある
と考えられている。またコンクリート魚礁の場合にも、
塗布された鉄化合物を介して植物プランクトンが増殖す
ると考えられる。For this reason, it is thought that steel reefs have the above-mentioned effect because iron is oxidized by oxygen in the sea and produces iron oxide (FezOz). Also, in the case of concrete reefs,
It is thought that phytoplankton proliferate via the applied iron compound.
しかし鉄鋼製魚礁は、鉄イオン生成までの時間が長くか
かり速効性がなく、さらに製造コストも高い。又鉄化合
物塗布コンクリート魚礁は鉄化合物塗付コストが高く、
さらに塗付物が作用する期間が短かい。However, steel reefs take a long time to generate iron ions, are not fast-acting, and are also expensive to manufacture. In addition, the iron compound coating cost for concrete reefs coated with iron compounds is high;
Furthermore, the duration of the application is short.
以上の問題点を解決するために本発明者らは、酸化鉄を
主成分として、若干の金属鉄を複合するコンクリート製
魚礁を着想した。In order to solve the above problems, the present inventors came up with the idea of a concrete reef made of iron oxide as a main component and a small amount of metallic iron.
本発明において、金属鉄（Ｆｅ）及び酸化鉄（Ｆｅｄ。In the present invention, metallic iron (Fe) and iron oxide (Fed) are used.

水中への溶出や鉄イオン生成に有利である。Converter dust generated in the steel manufacturing process can be used as the mixture of FezO3), which is extremely inexpensive in terms of raw materials. Converter dust not only has its components within the preferred range of the metallic iron and iron oxide mixture used in the present invention, but also has a particle size of 1 to 250μ, with most of the particles being fine particles of 50μ or less. It is advantageous for elution into seawater and production of iron ions.

発分に対応して新たな海水を３日に一度補給した。The reason for specifying the range of components in metallic iron and iron oxide mixtures is that concrete plates (30 cm x 30 cm
An experiment was conducted in which 10 pieces (10cm x 10cm) were immersed in 20 liters of seawater and the amount of Fe2O eluted while being forcibly stirred was investigated over a period of 3 months. In this experiment, fresh seawater was replenished once every three days to correspond to the amount of seawater that evaporated.

Ｏ、Ｆｅ、０３含有量が低下するため、ＦｅｚＱ＝溶出
開始時間が遅くなり好ましくない。As a result, (a) Metallic Fe is oxidized to become PeO, and then becomes Fe2O3 and is eluted. Therefore, even after a certain period of time has passed, F
e, a necessary component to sustain the elution of 03,
At 5% by weight or less, no elution of Fe2O3 was observed after 2 months. In addition, at 25% by weight or more, Fe is relatively
Since the O, Fe, and 03 contents decrease, the FezQ=elution start time is delayed, which is not preferable.
（ｂ） Ｆｅ、０１はそのまま海水に洗われてただち

量が半減し好ましくない。(b) Fe, 01 is immediately eluted as it is washed with seawater, and is necessary for exhibiting rapid effect as a component that generates iron ions. For this purpose, if it contains more than 10% by weight, a specified amount of Pe5O will be in the mouth for 2 weeks after contact with seawater.
,, Elution is observed and desirable. When the concentration exceeds 50%, the elution of PezO:+ becomes too rapid, and the amount of elution decreases by half in one month or more, which is not preferable.
（ｃ） ＦｅＯは酸化されてＦｅｚＯ＋となり溶出す

長期間にわたり所定量のＦｅ、０．の溶出を持続させる
ため２０〜６０ｆｉ量％必要である。(c) FeO is oxidized and becomes FezO+ and is eluted, so it has an intermediate role between metal Fe, Fe, and O.
A predetermined amount of Fe, 0. 20 to 60 fi amount % is required to sustain the elution of .

遊離石灰を含有するセメントは好ましくない。Next, let's talk about cement. The type of cement is not particularly limited, and the amount necessary for producing concrete may be blended into the metallic iron and iron oxide mixture, and the blending amount is 5 to 30% by weight based on the metallic iron and iron oxide mixture. desirable. However, cement containing free lime, which forms so-called water scale in seawater, is not preferred.

ｉＯ２，ＰはＰ２Ｏ，、ＦはＣａＦｚ等が用いられる。The reason why the concrete surface is made porous using cement containing a foaming agent is to increase the surface area of the reef, thereby eluting PezO= quickly and over a wide range. The foaming agent is not specific, but it is a metal suitable for boat fishing! In this case, Ca (Off) z produced by hydrolysis of cement and f/2 react as shown below to generate H2 gas. 2812 +3Ca(

The reason for including I will be described. These elements are
It is an ingredient for growing phytoplankton and seaweed, and by including these ingredients, more fish will gather and their growth will be faster. Therefore, it is desirable that one or more of these elements be contained in the concrete in an amount of about 0.2 to 5% by weight. If it is less than 0.2% by weight, there is no effect, and if it is more than 5% by weight, the effect is weakened. These elements may be contained as harmless compounds. For example, Sr is
iO2, P is P2O, F is CaFz, etc.
