【発明の詳細な説明】 （産業上の利用分野） 本発明は、ウナギ等の養魚用飼料の製造方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for producing feed for cultivating fish such as eel.
（従来の技術）
例えば、食用ウナギの養殖は、ウナギの稚魚を飼育する

け用飼料が開発されている。(Prior Art) For example, the cultivation of eels for food starts with raising eel fry, but eel fry do not have the habit of feeding mixed feed from the beginning. Therefore, in general, earthworms, which show strong palatability, were used as feed to feed young eels in order to develop feeding habits, but now artificial feeds have been developed.

しかしながら、上述した養魚用飼料においては。Conventionally, as fish feed used as artificial feeding feed for glass eels, for example, Japanese Patent Application Laid-Open No. 62-138149
As stated in the publication, squid is the main ingredient,
This is mixed with krill, nutritional supplements, and attraction aids, and this mixture is formed into a paste, which is freeze-dried and then powdered to further improve storage stability6 (Invention However, in the fish feed mentioned above.

。If you add water to freeze-dried feed to make it into a paste and then throw it into water during use, the paste-like feed will not retain its shape and will dissolve or break apart.
There are disadvantages in that food retention is poor, resulting in deterioration of water quality in aquaculture ponds and aquaculture tanks, and a decrease in the feeding rate of eels.
本発明は養魚用飼料の摂餌率を向上すると共に、養殖池
や養殖槽の汚染を少なくすることを目的とする。The present invention aims to improve the feeding rate of fish feed and to reduce contamination of aquaculture ponds and aquaculture tanks.
（課題を解決するための手段）
上記目的を達成するため２本発明は、イカを主成分とし

燥後粉末化する。(Means for Solving the Problems) In order to achieve the above object, the present invention forms a paste-like mixture of squid as a main component, krill, nutritional supplements, and attraction supplements, Sodium alginate and active gluten are added as a binder in an addition ratio of 1:0.5 to 1:4 and in a total amount of 1 to 5% by weight, and cyclodextrin is added as a denaturation inhibitor in an amount of 3. It is added within a range of 8% by weight and powdered after drying.
粘結剤としてのアルギン酸ナトリウム及び活性グルテン
を添加することにより、保形性と溶出防止効果を高める
ことができる。By adding sodium alginate and active gluten as binders, shape retention and elution prevention effect can be enhanced.
これらのアルギン酸ナトリウム及び活性グルテンの合計
添加量が５重量％を越えると、飼料が固くなって養魚が
喰い付けなくなったり、消化不良をおこしたりする。ま

て養魚槽や養殖池を汚染する。これらの粘結剤の合計添
加量は、好ましくは、２．５〜３．５重量％である。If the total amount of sodium alginate and active gluten added exceeds 5% by weight, the feed becomes hard, making it difficult for farmed fish to eat or causing indigestion. Furthermore, if the total amount added is less than 1% by weight, the feed will become loose or leached out when added to a fish tank or aquaculture pond, contaminating the fish tank or aquaculture pond. The total amount of these binders added is preferably 2.5 to 3.5% by weight.
また、アルギン酸ナトリウムと活性グルテンとの添加比
が、アルギン酸ナトリウム「１」に対して活性グルテン
がｒｏ、５Ｊ未満であると、飼料がくずれ（バラク）易
くなって餌持ちが悪くなる。In addition, if the addition ratio of sodium alginate to active gluten is less than ro, 5 J of active gluten to sodium alginate, the feed tends to crumble, resulting in poor feed retention.
また、アルギン酸ナトリウム「１」に対して活性グルテ

なくなる。アルギン酸ナトリウムと活性グルテンとの添
加比は、好ましく、アルギン酸ナトリウム「１」に対し
て活性グルテンが−ｒ０．７５〜１．５」である。Furthermore, if the amount of active gluten exceeds ``4'' per ``1'' of sodium alginate, the feed becomes cake-like and cannot be eaten. The addition ratio of sodium alginate and active gluten is preferably "1" of sodium alginate and -r of active gluten of 0.75 to 1.5.
これらのアルギン酸ナトリウムと活性グルテンの添加量

３．５重量％であり、活性グルテンが０．５〜４．０重

状になって喰いちぎれなくなる。The amounts of sodium alginate and active gluten added are more preferably 0.5 to 0.5.
3.5% by weight, and active gluten is 0.5-4.0% by weight. In this case, sodium alginate is 0.5
If it is less than 3.5% by weight, the feed will easily dissolve.
If the weight percentage is exceeded, the feed becomes hard. Additionally, if the amount of active gluten added is less than 0.5% by weight, the feed will become bulky (
When the amount exceeds 4.0% by weight, the feed becomes cake-like and cannot be easily eaten.
更に、変性防止剤としてのサイクロデキストリンを添加
することにより、乾燥による変性を防止して、粘結性を
維持することができる。Furthermore, by adding cyclodextrin as a denaturation inhibitor, denaturation due to drying can be prevented and caking properties can be maintained.
このサイクロデキストリンの添加量が３重量％未満であ

好ましくは、５〜８重量％である。If the amount of cyclodextrin added is less than 3% by weight, the storage period will be shortened, and if it exceeds 8% by weight,
Although it has a longer shelf life, it can cause indigestion and reduce the attracting effect. The amount of cyclodextrin added is
Preferably it is 5 to 8% by weight.

なる。In this way, by adding sodium alginate and active gluten as binders in the above amounts and addition ratios, and adding cyclodextrin in the above amounts, it is possible to prevent a decrease in caking properties due to denaturation of the feed caused by drying. As a result, it is possible to maintain the shape retention when the bait is thrown into water and prevent elution and flaking, resulting in a paste-like feed with a shape and consistency suitable for feeding fish, making it easy to feed fish. Feed rates are improved and contamination of fish tanks and ponds is reduced.
また、ペースト状混合物を乾燥する方法としては、蛋白
質に変性を来たさない温度で乾燥する方法が好ましく、
例えば真空凍結乾燥、凍結乾燥等を挙げることができる
。In addition, as a method for drying the paste mixture, it is preferable to dry at a temperature that does not cause denaturation of the protein.
Examples include vacuum freeze-drying and freeze-drying.
更に、本発明は、例えばシラスウナギの幼魚用の飼料、
シラスウナギの成魚の飼料及びその他の養魚の飼料の製

It can be used in the production of adult glass eel feed and other fish feed.
