【発明の詳細な説明】 ３、発明の詳細な説明 〔産業上の利用分１） ） 不発明はシラスウナギ用飼料に関する。[Detailed description of the invention] 3. Detailed description of the invention [Industrial use 1)] The invention relates to feed for glass eels.
〔従来の技術及び発明が解決しようとしている問題点〕
シラスウナギは、ウナギの仔稚魚であるが、ウナギの食
用としての消費が増大してきているので、シラスウナギ
を飼育する飼料が必要になってきている。[Problems that the prior art and invention are trying to solve]
Glass eels are young eels, and as the consumption of eels for food has increased, feed for raising glass eels has become necessary.
従来用いられてきたシラスウナギ用飼料としては、天然
産のイトミミズがあげられる。イトミミズは河川の底に
存在するものを採取し使用するが、汚物、病原菌などを
シラスウナギの飼育槽に持ち込むケースも生じ、この場
合シラスウナギの全滅という多大の損害が生ずる場合も
ある。一方、我が国では、河川の汚染などによジイトミ
ミズの量が減少してきており、そのため外国からの輸入
に頼っている。又、イトミミズは生き物のため、その保
存にも問題点がある。A conventional feed for glass eels includes naturally produced worms. Earthworms collect and use what is present on the river bottom, but there are cases where filth, pathogenic bacteria, etc. are brought into the glass eel rearing tanks, and in this case, great damage may occur, such as the extinction of the glass eels. On the other hand, in Japan, the amount of earthworms has been decreasing due to river pollution, and for this reason we are relying on imports from foreign countries. Also, since the earthworm is a living creature, there are problems in its preservation.
又、イトミミズの代ジに、魚介類例えばイワシ、サバ、
アサリ、カキなどをミンチしたものがあるが、これらを
用いると飼育槽での散逸が多く、飼料効率も低く、コス
ト、環境保存などの点から欠点が多い。最近、特開昭６
０−２６２５５７号公報によれば、イカを主成分とする
シラスウナギ用飼料が考え出されているが、この飼料で
用いるイカは、生のイカであり、長期の保存に鎖点が存
在する。この難点を解決するために、冷凍にしなけれは
ならないが、その流通、保持にコスト及び手間がかかり
、その上保持中に成分変化が激しい。そして、使用時に
チョッパーなどで粉砕してミンチ状とするが、多量のも
のを短時間に処理するのは、かなり面倒である。In addition, seafood such as sardines, mackerel,
There are minced clams, oysters, etc., but when these are used, there is a lot of dissipation in breeding tanks, feed efficiency is low, and there are many disadvantages in terms of cost, environmental preservation, etc. Recently, Tokukai Showa 6
According to Publication No. 0-262557, a feed for glass eels containing squid as a main ingredient has been devised, but the squid used in this feed is raw squid, and there are problems with long-term storage. To solve this problem, it is necessary to freeze the food, but its distribution and storage are costly and time-consuming, and furthermore, the components change drastically during storage. When used, it is ground into minced meat using a chopper or the like, but it is quite troublesome to process large quantities in a short period of time.
又、シラスウナギの成長に応じて、飼料の硬さを調節す
るのも容易なことではない。Furthermore, it is not easy to adjust the hardness of feed according to the growth of glass eels.
本発明者は、現在用いられているシラスウナギ用飼料の
このような欠点を有しない飼料について検討した紹呆、
本発明を見い出した。The present inventor has studied feeds for glass eels that do not have these drawbacks of currently used feeds for glass eels,
The present invention has been discovered.
即ち、本発明は魚介類の凍結乾燥粉末を主成分とするシ
ラスウナギ用飼料に関する。That is, the present invention relates to a glass eel feed containing freeze-dried powder of seafood as a main ingredient.
本発明で用いられる魚介類としては、例えばイワシ、サ
バ、カツオ、イカ、エビ、アサリ、カキが挙げられ、こ
の中でイカ、エビ、カツオ特にイカが好ましい。そして
これらの混合物も用いられる。本発明における魚介類の
凍結乾燥粉末を得るためには一般的にはこれら魚介類を
は−ストにした後粉砕して粉末状とするが、その他の魚
介類をそのまま凍結乾燥した後粉砕するかあるいは魚介
類のは−スト状物と粘結剤とを混合した後凍結乾燥しそ
の後粉砕して調製することもできる。なかでも魚介類バ
ーストに粘結剤を混合した後凍結乾燥したものが特に好
ましい。Examples of the seafood used in the present invention include sardines, mackerel, bonito, squid, shrimp, clams, and oysters, among which squid, shrimp, and bonito are particularly preferred, with squid being particularly preferred. Mixtures of these can also be used. In order to obtain the freeze-dried powder of seafood in the present invention, these seafood are generally roasted and then ground into a powder, but other seafood may be freeze-dried as is and then ground. Alternatively, it can also be prepared by mixing fish and shellfish starch with a binder, freeze-drying the mixture, and then crushing the mixture. Among these, particularly preferred is seafood burst mixed with a binder and then freeze-dried.
又、本発明で用いられる粘結剤としては例えばα化でん
粉、グアガム、アルギン敵ナトリウム、キサフタ／ガム
、カルボキシメチルセルロース、グルテンなどが挙げら
れる。Examples of the binder used in the present invention include pregelatinized starch, guar gum, sodium alginate, xafta/gum, carboxymethyl cellulose, and gluten.
粘結剤は前記したように（ｉ結乾燥処理の前に加える外
、凍結乾燥処理後に添加することもできる。粘結剤の量
は、魚介類に対し約０．２〜５重量％好ましくは約０．
５〜３重量％の範囲がよい。５ｔｔ％より多いと得られ
た飼料が硬くなり、シラスウナギが食べ下すことが困雌
にｙＢ、一方０．２重−Ｍｅ ％より少いと、飼料の水
中への散逸が生じ易い。As described above, the binder can be added before the freeze-drying process or after the freeze-drying process.The amount of the binder is preferably about 0.2 to 5% by weight based on the seafood. Approximately 0.
A range of 5 to 3% by weight is preferable. If the amount is more than 5 tt%, the resulting feed becomes hard and difficult for glass eels to eat, while if it is less than 0.2 tt%, the feed tends to dissipate into the water.
本発明のシラスウナギ用飼料には通常番魚飼料に使用さ
れる成分、すなわち各種ビタミン類、ミネラル類を添加
することもできろ。The glass eel feed of the present invention may contain ingredients commonly used in guard fish feed, ie, various vitamins and minerals.

4.8 6.9 [Effects] As can be seen from the above-mentioned examples and diagnostic examples, the feed of the present invention improves the palatability and growth of glass eels compared to the conventionally used raw worms. It has an effect that is no less effective. In addition, the feed of the present invention does not have the disadvantages of raw Japanese worms, such as difficulty in obtaining them and contamination, and has excellent distribution and storage properties. It can be said that it is an excellent feed compared to

も良く、嗜好性も失われない。In addition, drying methods include heat drying in addition to freeze drying, but as can be seen from the examples and reference examples, feed freeze dried according to the present invention does not require adjustment of the amount of water added during feeding. It is easy to use, and the binding properties of seafood, especially squid meat, are not lost and there is little disintegration in water. Furthermore, even with the same water content, it goes without saying that freeze-dried eels have less protein denaturation than heat-dried eels, and glass eels grow better and do not lose their palatability.

い。On the other hand, if seafood fish stocks are directly heat-dried, as seen in the case of freeze-drying raw Japanese worms, the feeding rate and growth of glass eels are extremely poor, and this method is not practical.

合せた硬さに調節することが出来る。As is clear from the above, the feed of the present invention has the same palatability for glass eels as the conventionally used raw worms, and has superior storage stability and distribution compared to the worms in the soil. In addition, compared to feed containing raw squid as the main ingredient, it has excellent storage stability and distribution, and there is almost no change in quality.Furthermore, when feeding, the hardness can be adjusted to suit the growth of the glass eel. You can.
