【発明の詳細な説明】
本発明は電解作用を利用したいけすにおける魚類の新規
養殖方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for cultivating fish in cages using electrolytic action.
水産養殖業者はいけす内における放養尾数をなるべく多
くし、歩留まりの多い健全な魚類を育てることに日夜頭
を痛めている。Aquaculture farmers are struggling day and night to increase the number of fish in cages and raise healthy fish with high yields.
しかしながら、いけす内の放養密度を高くすることは必
然的に魚病を誘発し、歩留まりが悪くなるばかりか発育
成長に悪影響を及ぼすことが知られている。However, it is known that increasing the stocking density in the cage inevitably induces fish diseases, which not only reduces yield but also has a negative effect on growth.
従来、このような問題を解決するために各種の治療剤、
予防剤または栄養強化餌料を与えたり、また酸素補給装
置や温度コントロール装置などを設備したりしているが
人手と手数を要するなどその運営管理上に問題があるば

しも満足する結果が得られていなかった。Conventionally, various therapeutic agents,
Although preventive agents or nutritionally enriched feeds are given, and oxygen supplementation equipment and temperature control equipment are installed, these methods not only pose operational management problems as they require manpower and labor, but also have problems with the growth and yield of farmed fish. However, satisfactory results were not always obtained.
本発明者はこのような現状を考慮し、電解作用を利用す
ることによって運営管理がきわめて簡単でしかも養殖魚
の発育成長と歩留まりの向上にきわめて優れた新規養殖
方法を開発した。In consideration of the current situation, the present inventors have developed a new aquaculture method that utilizes electrolytic action and is extremely simple to operate and manage, and is also extremely superior in improving the growth and yield of cultured fish.
すなわち本発明の要旨は、アルミニウム、マグネシウム

および前記陽極と陰極との間に流れる微弱電流による電
界効果により養殖魚の発育成長と歩留まりを向上させる
ことを特徴とする魚類の電解養殖方法である。That is, the gist of the present invention is to install an electrolytic device in which aluminum, magnesium, or zinc, or an alloy thereof, and a metal (cathode) having a higher potential than this metal (anode) by an electric wire, in an aquaculture cage, Through its electrolytic action, hydroxides of aluminum, magnesium, or zinc are produced on the surface of the anode, and calcium carbonate, etc. are produced on the surface of the cathode, and the chemical effects of these compounds and the weak current flowing between the anode and the cathode This is an electrolytic farming method for fish, which is characterized by improving the growth and yield of farmed fish through the electric field effect.
つぎに本発明の方法を図面に基づいて説明する。Next, the method of the present invention will be explained based on the drawings.
第１図は本発明で使用される電解装置を設置したいけす
の概略断面図である。FIG. 1 is a schematic sectional view of a cage in which an electrolysis device used in the present invention is installed.
棒状のアルミニウム合金１（陽極）の一端から突き出た
鋼製心金に電線２を接続し、この電線２の他端に銅製パ
イプ３（陰極）を接続する。An electric wire 2 is connected to a steel mandrel protruding from one end of a rod-shaped aluminum alloy 1 (anode), and a copper pipe 3 (cathode) is connected to the other end of this electric wire 2.
上記陽極１は電解作用により溶解した時に、微粒状の雑
菌類を吸着したり、また魚類の体内に吸収されて細菌の
侵入阻止作用や消化助長作用として働く水酸化物を生じ
る金属であり、たとえばアルミニウム合金の他にマグネ
シウム、亜鉛およびその合金である。The anode 1 is a metal that, when dissolved by electrolysis, adsorbs microscopic bacteria and generates hydroxide that is absorbed into the body of fish and acts as a deterrent to bacterial invasion and as a digestive aid. In addition to aluminum alloys, these include magnesium, zinc, and their alloys.
また、上記陰極３は陽極１より責な電位を有する金属で
、かつ陽極１と適当な電位差を有するものであればよい
。Further, the cathode 3 may be any metal as long as it has a higher potential than the anode 1 and has an appropriate potential difference with the anode 1.
なお、上記陽極と陰極との間に抵抗あるいは直流電源装
置を挿入して発生電流を調節することもできる。Note that the generated current can also be adjusted by inserting a resistor or a DC power supply between the anode and the cathode.
このように構成された電解装置をいけすの外枠４あるい
は内枠から上記陽極と陰極を適宜の間隔をもって吊り下
げ固定する。The electrolysis device thus constructed is fixed by suspending the anode and cathode at an appropriate interval from the outer frame 4 or inner frame of the cage.
そして、電解装置が作動することによって微弱電流が流
れていけす内に電界が形成されるので、養殖魚の餌とな
る小魚や動物性プランクトン類が集まり易い環境になり
また電解作用によって析出した水酸化アルミニウム、水
酸化マグネシウム、水酸化亜鉛、硫酸アルミニウム、炭
酸マグネシウムなどの化学的効果によって病害にかかり
にくい環境が作られる。When the electrolytic device operates, a weak current flows and an electric field is created inside the cage, creating an environment where small fish and zooplankton, which are used as food for cultured fish, easily gather.Aluminum hydroxide is precipitated by the electrolytic action. Chemical effects such as , magnesium hydroxide, zinc hydroxide, aluminum sulfate, and magnesium carbonate create an environment that is less susceptible to diseases.
