- the body length is 150-250 ⁇ m, and it is in the shape of a pot. It constantly filters the floating microalgae in the water while moving the cilia, and uses it as a nutrient source to live in brackish waters. Therefore, it has the habit of gathering towards the light because it seeks microalgae for photosynthesis.
- Nutritional components include 60% (w / w) protein per dry matter, 10% (w / w) total fat, 15% (w / w) carbohydrates, and 8% (w / w) ash content. It is characterized by high nutritional value. This rotifer can use the raw chlorella which became industrially mass-produced as the feed, and the produced live rotifer is used as a suitable biological feed of hatching larvae.

More preferably, sodium selenite may be added in the range of 60 to 600 ⁇ g / L for strengthening.
- microalgae there are no restrictions on the culture conditions for microalgae. For example, when the temperature is in the range of 5 ° C. to 40 ° C., the culture solution is aerated and stirred, and irradiated with light as necessary, and microalgae can be grown by culturing for 0.5 to several days.

- Example 1 Production of selenium-containing rotifer using selenium-containing raw chlorella as a feed
- the selenium-containing raw chlorella was cultured using a 10 L jar fermenter.
- the chlorella strain (Chlorella vulgaris) slant owned by our company was inoculated aseptically into the Sakaguchi flask of dark culture basal medium, and precultured at 28 ° C. After the utilization of glucose, it was transplanted to a 10 L jar fermenter, and selenium-enhanced chlorella was aseptically cultured.
- the culture conditions were medium volume 6 L, temperature 36 ° C., aeration 3 L / min, pH 7.0, stirring speed 300 rpm / min.
- Medium composition is glucose 80 g / L, potassium phosphate 2.0 g / L, magnesium sulfate 2.0 g / L, Fe ⁇ EDTA 4.8 mg / L, trace mineral A 5 ( ⁇ 10) 1.08 ml / L, vitamin B 12 Sodium selenite was added to basal media of 2.4 mg / L and urea 6.0 g / L at concentrations of 5.4 ⁇ g / L, 18 ⁇ g / L, 54 ⁇ g / L, 180 ⁇ g / L and 540 ⁇ g / L, respectively. The culture was started using the sample.
- a culture test was carried out by feeding a total of four types of test feed of powder to a rotifer (S type). As test conditions, 50 L of artificial seawater having a 1.5% (w / w) salt concentration was put in each 100 L panlite water tank, the water temperature was 28 ° C., the aeration was 45 L / min, and the starting rotifer density was 80 individuals / ml.
- the amount of food to be fed was cultured for 1 week on the basis of 0.5 to 0.7 ⁇ g / rotifer individual / day in terms of dry alga mass. The results are shown in FIG.
- the selenium-containing raw chlorella group had a higher growth rate of the rotifer than the conventional method.
- there was a clear difference in the form of feed between the raw state and the powdered state and almost no growth of rotifers was observed in the powdered test plots. This is thought to be due to the fact that the raw chlorella of the feed was freeze-dried, the cells were broken, and nutrient components such as protein were eluted in the rotifer's breeding water, resulting in an oligotrophic state. This was supported by the ongoing contamination of the breeding water in both districts fed with powdered feed.
- the rotifer (S type) culture test was performed using the test foods with different selenium concentrations prepared by the above method (selenium content 0 ⁇ g, 6 ⁇ g, 19 ⁇ g, 58 ⁇ g, 191 ⁇ g, 570 ⁇ g / 100 g per dry weight). did.
- 40 L of artificial seawater having a 1.5% (w / w) salt concentration was put in each 50 L panlite water tank, the water temperature was 28 ° C., the aeration was 45 L / min, and the starting rotifer density was 80 individuals / ml.
- the amount of food to be fed was cultured for 4 days on the basis of 0.5 to 0.7 ⁇ g / rotifer individual / day in terms of dry alga mass.
- the growth of rotifer was excellent when the selenium concentration in the feed was in the range of 19 to 191 ⁇ g / 100 g (per dry alga body weight). This result shows that selenium enrichment of the feed is effective for the growth of rotifer.
- the selenium content of the rotifer was measured after the test, and the result is shown in FIG. From the results of FIG. 3, the selenium content in rotifers cultured with raw chlorella (selenium concentration: below detection limit) produced by the same method as the conventional method was below the detection limit ( ⁇ 5 ⁇ g / 100 g). In contrast, the selenium content in rotifers cultured with selenium-containing raw chlorella (selenium concentration of 6 to 570 ⁇ g / 100 g) increases with an increase in the selenium concentration in the raw chlorella, up to 200 ⁇ g / 100 g (per dry matter). ) Live rotifer was able to be produced.

Pre-culture was performed for 2 weeks at an illuminance of 2000 lux and a water temperature of 20 ° C.
- the culture conditions were a medium volume of 25 L, 5% CO 2 aeration and stirring at 3 L / min, an illuminance of 2500 lux, and a water temperature of 20 ° C.
- the composition of the medium was selenite in 0.5 g / L potassium nitrate, 0.1 g / L sodium hydrogen phosphate, 4.15 mg / L Fe.EDTA, 0.1 ml / L trace mineral A 5 ( ⁇ 10)
- the culture was started using sodium 50 ⁇ g / L dissolved in diluted seawater (1% w / w salt).
- the product was harvested and washed three times with pure water to obtain 20 g of live Nannochloropsis algae (converted to dry matter) having a selenium content of 480 ⁇ g / 100 g (per dry matter).
- Example 3 Breeding test of flounder larvae using selenium-containing rotifer A flounder (Paralichthys olivacens) larvae breeding test was conducted using selenium-containing rotifers produced using selenium-containing raw chlorella as a feed.
- the breeding test conditions are as follows: 500 L filtered seawater is introduced into each 600 L circular polycarbonate aquarium, water conversion rate is 100% / day, water temperature is 17-20 ° C., aeration is 500 ml / min. 0.05 mm * 1 ) 1.1 ⁇ 10 4 were accommodated.

10Lジャーファーメンターを用いて、セレン含有生クロレラの培養を行った。当社保有のクロレラ株(Chlorella vulgaris)スラントから暗培養基礎培地の坂口フラスコに無菌的に植菌して、28℃で前培養を行った。グルコースの資化終了後に10Lジャーファーメンターに植え継ぎ、セレン強化クロレラの無菌培養を行った。培養条件は、培地液量6L、温度36℃、通気3L/分、pH7.0、撹拌速度300rpm/分とした。培地組成は、グルコース80g/L、リン酸カリウム2.0g/L,硫酸マグネシウム2.0g/L、Fe・EDTA4.8mg/L、微量ミネラルA5(×10)1.08ml/L、ビタミンB12 2.4mg/L、尿素6.0g/Lの基礎培地に、亜セレン酸ナトリウムを5.4μg/L、18μg/L、54μg/L、180μg/L、540μg/L、の濃度で各々加えたものを用いて、培養を開始した。増殖中に高度不飽和脂肪酸(ドコサヘキサエン酸60%濃度)1.5g/Lを各々添加し、グルコースの資化終了後に純水で3回水洗を行い、セレン含有量6~570μg/100g(乾燥物重量当たり)の範囲で生クロレラ藻体を各々200g(乾燥物換算)得た。
図3の結果より、従来法と同様の方法で生産された生クロレラ(セレン濃度:検出限界以下)で培養したワムシ中のセレン含量は、検出限界(<5μg/100g)以下であった。それに対して、セレン含有生クロレラ(セレン濃度 6~570μg/100g)で培養したワムシ中のセレン含量は、生クロレラ中のセレン濃度の増加に伴って増加し、最大で200μg/100g(乾燥物当り)の生きたワムシを生産できた。
セレン含有生ナンノクロロプシスを餌料としたセレン含有ミジンコの生産

セレン含有ワムシを使ったヒラメ仔魚の飼育試験
セレン含有生クロレラを餌料として生産したセレン含有ワムシを用いて、ヒラメ(Paralichthys olivacens)仔魚の飼育試験を実施した。飼育の試験条件は各600L容円型ポリカーボネイト水槽に、500Lのろ過海水を投入して、換水率100%/日、水温17~20℃、通気500ml/分とし、孵化仔魚(体長2.1±0.05mm*1)を1.1×104尾収容した。試験餌料として、セレン含有ワムシ(セレン含量100μg/100g乾燥重量当たり)を用いて飼育を開始し、飼育水中のワムシ密度が6~12個体/mlとなるように1日2回給餌を行い、合計2水槽(a、b)で17日間飼育試験を行った。その結果、試験期間中のヒラメ仔魚の摂餌は旺盛で、順調な成育がみられた。
従来法による生クロレラで培養したワムシを使ったヒラメ仔魚の飼育試験
従来の生クロレラを餌料として生産したワムシ(セレン濃度<5μg/100g:検出限界以下)を用いて、ヒラメ仔魚の飼育試験を実施した。飼育の環境条件及び給餌条件は、上記と同様とし、合計2水槽(c、d)で17日間飼育試験を行った。その結果、実施例3の場合とほぼ同様の成育がみられたが、飼育期間中の斃死個体数は増加した。
*2:網による30秒間空中露出後の生残率(n=50)
表1の各17日間のヒラメ仔魚飼育試験結果より、従来法で生産したワムシ給餌区に比べてセレン含有ワムシ給餌区は、体長に大きな差はみられなかったものの、生残率及び活力において優れていた。これは、ワムシ給餌期のヒラメ孵化仔魚にとってワムシ餌料のセレン強化が、その生残率や活力において大きく影響を与えることを示す。
