Abstract

<P>PROBLEM TO BE SOLVED: To provide a new method for artificially making Xenopus laevis lay eggs and hatch, and then breeding the Xenopus laevis by solving a problem such that there are many difficulties from its hatching until finishing up its transformation period in the breeding of the same. <P>SOLUTION: This method for breeding the Xenopus laevis is to artificially make the Xenopus laevis lay eggs and hatch, and then give yeast fungi in a state of dissolving the same in the water of an aquarium. As the timing of starting to give the yeast fungi as feed, the time of hatching, becoming tadpoles and starting to move is optimal. Since the yeast fungi are the form of nutrition capable of cleaning water clouded by the excrement of the tadpoles and also dissolved in the water, it is easy to control the concentration of them. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

発明の概要Summary of the Invention

（１）１９９５年から研究開発に取り組んでいる。試行を重ねた結果１９９６年には、とってもよい成果を得ることができた。その後さらに多くの実施方法にて試験研究を重ね順調な歩みを続けている。
（２）本発明は酵母菌を用いたアフリカツメガエルの発生及び飼育方法に関するものである。(1) Worked on research and development since 1995. As a result of repeated trials, in 1996, we were able to achieve very good results. Since then, we have continued to make steady progress by conducting trials and research with more implementation methods.
(2) The present invention relates to a method for generating and raising Xenopus laevis using yeast.

発明の詳細な説明Detailed Description of the Invention

発明の構成Structure of the invention

（１）アフリカツメガエルに人為的に産卵させ、孵化した後水槽の水に溶かし込む形で酵母菌を与える。
（２）餌としての酵母菌を与えるタイミングは孵化し、オタマジャクシになり、動き始めるころが最適である。
（３）酵母菌は排出物の尿素で濁った水を浄化する働きも認められ、栄養を損なわずに水質の管理が可能になる。
（４）水に溶け込んだ形の栄養分であるため濃度をコントロールすることが容易となる。
（５）成体の餌は、通常レバーを与えている。これに酵母菌を併用して与えてみたが経過は良好であった。(1) Xenopus is artificially spawned and hatched, and then yeast is given in the form of being dissolved in water in the aquarium.
(2) The best time to give yeast as bait is when it hatches, becomes tadpole, and begins to move.
(3) Yeast bacteria are also recognized to purify turbid water with the excreta of urea, and it is possible to manage water quality without losing nutrition.
(4) Since it is a nutrient dissolved in water, the concentration can be easily controlled.
(5) The adult bait usually gives a lever. This was given in combination with yeast, but the progress was good.

従来の方法とその欠点Conventional methods and their drawbacks

（１）アフリカツメガエルにレバー・ホウレンソウのすり身等の餌を与えて飼育すると水が濁り、汚染物質の影響で幼生が死んでしまった。
（２）発生から飼育にかけての失敗の多くは、水質管理・栄養の与え方・水温との関係のバランスが崩れてしまうことにある。
（３）孵化してから幼生に与える栄養の管理及び水質の汚染対策にいくつかの問題があった。(1) When Xenopus laevis was fed with food such as liver and spinach surimi, the water became cloudy and the larvae died due to pollutants.
(2) Many of the failures from occurrence to breeding are that the balance between water quality management, nutrition, and water temperature is lost.
(3) There were some problems in the management of nutrients given to larvae after hatching and the countermeasures against water pollution.

発明の効果The invention's effect

（１）一般の飼育では、孵化してから変態期を終了するまでが多くの困難を伴う。しかし、エトキン氏の実験から既に明らかなように自然変態では甲状腺ホルモン濃度が除に高まって行く。こうしたことから酵母菌には甲状腺ホルモンの分泌に密接な関係な関連作用があると考えられる。
（２）酵母菌を投与すると水が濁りにくくなる。このことは酵母菌が水質の浄化に大きく係わっていることを示している。(1) In general breeding, there are many difficulties from hatching to the end of the metamorphosis period. However, as is already clear from Mr. Etokin's experiment, thyroid hormone levels increase in natural metamorphosis. From these facts, it is considered that yeast has a closely related effect on the secretion of thyroid hormone.
(2) When yeast is administered, water becomes less turbid. This indicates that yeast is greatly involved in water purification.
