ている。Rotifers are the most important initial feed for aquatic seedlings, and the development of a mass culture method for rotifers using Nannochloropsis, yeast, concentrated freshwater chlorella, etc. has made it possible to dramatically increase seedling production. . However, even today, when cultivating rotifers, poor growth of the rotifers sometimes occurs, which can hinder seed production.
It is desired to establish a more stable and efficient culture method for rotifers.

い。It has been suggested that one of the reasons for the instability of rotifer culture is that the bacterial flora in the rotifer culture tank changes, making it impossible for the bacteria to supply the vitamin B12 necessary for rotifers. Although attempts have been made, it is still difficult to control this. Another option is to add vitamin Bll directly to the rotifer culture tank, but this requires a large amount of vitamin D22, 1 to 5 g per 1of rotifer culture tank, and the added vitamin is degraded by other bacteria, causing the rotifer to grow. However, it has not been put into practical use because vitamins cannot be used efficiently and it is not economical.
本発明の目的は、現在ワムシ餌料として広く使用されて
いる淡水産クロレラに、ワムシに必要なビタミンB42
を高濃度に含有させ、ワムシ餌料として供給することに
より、効率の良い、安定したワムシ生産を可能にする・
ワムシ餌料を提供することである。The purpose of the present invention is to add vitamin B4, which is necessary for rotifers, to freshwater chlorella, which is currently widely used as feed for rotifers.
By containing a high concentration of and feeding it as rotifer feed, efficient and stable production of rotifers is possible.

得ることができる。Chlorella with a high vitamin B□2 content can be obtained by adding vitamin B1□ to the culture solution during chlorella cultivation or to the chlorella suspension after culturing, and allowing the chlorella to absorb and accumulate the vitamin B1□.

量のビタミンB12を培養液中に加えてクロレラを培養
することにより、培養液に添加したビタミンB□2は。Chlorella usually uses nitrates, ammonium salts, urea, etc. as nitrogen sources, and other inorganic salts such as Ml-potassium, magnesium sulfate, ferrous sulfate, and organic substances such as glucose, acetic acid, and amino acids are added as necessary. Culture is carried out using a culture solution under light or dark conditions with aeration or stirring. When preparing these culture solutions, vitamin B□2 is added to the culture solution by adding an appropriate amount of vitamin B12 to the culture solution and culturing chlorella.
培養終了時にはほぼすべてがクロレラ中に吸収。At the end of culture, almost all of it is absorbed into chlorella.
蓄積され、非常に効率よくビタミンB1□高含有クロレ

条件は通常の培養の場合と同様である。chlorella with a high vitamin B1□ content can be produced very efficiently. The culture conditions for Chlorella at this time are the same as those for normal culture.

レラの製造が可能である。In addition, if chlorella is cultured according to the culturing method of Shinnaori Lorella, and an appropriate amount of vitamin B1□ is added to the chlorella suspension at the end of the culture and maintained, approximately Added vitamin B12 can be absorbed and accumulated in chlorella 100% in about 0 hours. According to this method, compared to the method of adding vitamins when preparing the culture solution, the vitamins can be absorbed and accumulated in a shorter time, and there is no decomposition of the vitamins due to sterilization, etc., so it is a more efficient way to increase vitamin B□2. It is possible to produce chlorella containing chlorella.

り、200μg/Ωを超える添加では効率は低くなる。Vitamin D into the culture solution or chlorella suspension at that time
The amount of 22 added varies depending on the concentration of chlorella produced by the culture solution, the concentration of chlorella in the chlorella suspension, etc. For example, a culture solution in which 7 gIQ of chlorella is produced or the same concentration of chlorella lI! In li suspension,
The amount of vitamin B1□ added to the culture solution or chlorella suspension is in the range of 0.5 to 200 μg/11.
It is possible to produce chlorella containing 1□.1 It is possible to produce chlorella containing various concentrations of vitamin B42, but the range of 0.5 to 100 μg IQ is particularly efficient, and adding more than 200 μg/Ω Efficiency will be lower.

ムシ用餌料として利用する。In the present invention, chlorella that absorbs and accumulates vitamin B1□ at a high concentration is produced in this way, and this chlorella is used as feed for rotifers.

工業的に生産されているワムシ餌料である酵母、淡水産
濃縮クロレラに比べ、ワムシの生育が非常に良くなり、
したがってワムシの効率的な安定生産が可能となる。こ
の場合、ビタミンB1□含有クロレラは生あるいは乾燥
物の使用が可能である。By using chlorella containing at least 20 μg/100 g of vitamin B1□, preferably 100 to 200 μg/100 g, as feed for rotifer production, yeast and freshwater concentrates, which are conventional industrially produced rotifer feed, can be used. Compared to chlorella, rotifer growth is much better,
Therefore, efficient and stable production of rotifers becomes possible. In this case, the vitamin B1□-containing chlorella can be used fresh or dried.
またワムシへの投餌方法は毎日、1回または数回適当量
のクロレラを与えるのが一般的であるが、少量の連続的
な投餌または他の餌料と混合して与えることも可能であ
る。In addition, the general method of feeding rotifers is to feed an appropriate amount of chlorella once or several times every day, but it is also possible to feed it continuously in small amounts or by mixing it with other foods. .
従来ワムシのビタミンB82は、ワムシ培養槽内に発生

の増殖が良くなるとともに、ワムシ培養の安定化が可能
となる。Conventionally, vitamin B82 for rotifers was supplied by bacteria generated in rotifer culture tanks, and it was difficult to suppress such bacteria, which was one of the causes of instability in rotifer culture. By feeding rotifers with chlorella containing a high concentration of vitamin B1□, it becomes possible to stably supply vitamin B12 to rotifers, which improves rotifer proliferation and stabilizes rotifer culture.
この場合、クロレラは100%ワムシに取り込まれるた

率的にワムシに利用され、ワムシ培養槽100tに対し
クロレラに含有させて添加するビタミンBL2は0.0
2〜0.1gと非常に少量で有効である。In this case, since 100% of chlorella is taken up by rotifers, the vitamin D22 contained in chlorella is utilized very efficiently by rotifers, and the amount of vitamin BL2 added to chlorella per 100 tons of rotifer culture tank is 0. 0
It is effective in a very small amount of 2 to 0.1 g.
また魚類に対しても、ビタミンD22は有効であり、欠

有するワムシの生産が可能となる。It is also known that vitamin D22 is effective for fish, and that deficiency causes a decrease in blood cell count and hemoglobin content. Therefore, by culturing rotifers with chlorella containing vitamin 81□, it is possible to produce rotifers that have excellent nutritional value even for fish.

地を使用し、3日間培養した。Example 1 Vitamin B12 was added to the culture solution of various chlorella strains and cultured, and the absorption and accumulation of vitamin B12 by chlorella was investigated. The culture conditions were 25°C, 3-5klux, glucose 20gIQ, urea 1.5g#! , calcium phosphate 1.2g/L magnesium sulfate 0.6gI
A medium containing Q, iron IEDT^15 mg/III, trace metal A5 solution 1 mQ/Q, and vitamin D2240 μg/11 was used and cultured for 3 days.

分を収穫し、一部分で新たに培養を開始した。Rotifers were cultured using conventionally cultured chlorella that does not contain vitamin D22, and their feed value was compared. Rotifers were cultured in 15fl artificial seawater at 22-24°C under aeration conditions. The number of rotifers was measured every day, and chlorella was fed in an amount appropriate to the number of rotifers. The rotifers fed the vitamin-containing chlorella had higher egg weights on the fourth and fifth days, and the rotifers multiplied much better. On the 7th day, the rotifer density reached 605/d, so most of the rotifers were harvested and a new culture was started on a portion.
