Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は魚類の養殖用飼料、特にうなぎ等の淡水魚類の
養殖用飼料に関する。TECHNICAL FIELD The present invention relates to a feed for aquaculture of fish, particularly a feed for aquaculture of freshwater fish such as eel.
従来の魚類の養殖、特にうなぎ等の淡水魚類の養殖にお
ける飼料としては、「いわし」、「さんま」または「さ
ば」等の廉価な大衆魚を冷凍保存し、適当な形態にした
もの、搾油または溶剤抽出により脱脂、乾燥した魚粕
に、再び精製加工した魚油を添加したもの等が通常用い
られていた。As a feed for conventional aquaculture of fish, particularly for aquaculture of freshwater fish such as eel, frozen popular fish such as "sardines", "samma" or "mackerel" are frozen and stored in an appropriate form, oil or It has been customary to add fish oil that has been refined and processed again to fish meal that has been degreased and dried by solvent extraction.
このように、従来の魚類の養殖用飼料は魚油を含有する
飼料であるが、これらの魚油を含む飼料で養殖されたう
なぎ等の魚は、飼料中に魚油と類似ないし関連した脂肪
酸組成の体脂肪を保有し、これら養殖魚例えばうなぎは
天然うなぎと体脂肪の組成、性状が全く異なり、その結
果香味や保存性は天然うなぎに比べて劣るものであっ
た。As described above, the conventional feed for aquaculture of fish is a feed containing fish oil, but fish such as eel cultivated with a feed containing these fish oils have a fatty acid composition similar to or related to fish oil in the feed. Since they have fat, these cultured fish such as eel have completely different composition and properties of natural eel and body fat, and as a result, their flavor and storability are inferior to those of natural eel.
すなわち、従来の飼料中には魚油を含むため、その魚油
成分である高度不飽和酸、例えばいわし酸等を含有する
ので、それから養殖される魚は魚油臭が発生しやすく、
香味の点及び保存性の点で問題があった。That is, since the conventional feed contains fish oil, it contains a highly unsaturated acid which is its fish oil component, for example, sardine acid, etc., so fish cultivated from it tend to have a fish oil odor,
There were problems in terms of flavor and storability.
本発明者らは前記の問題点を解決すべく種々研究の結
果、通常用いられる飼料である魚粉を穀物油を添加した
飼料が生育は勿論、成長した成体の香味、保存性におい
て通常の魚油を添加した場合よりも極めてすぐれた養殖
魚を得るのに有効であることを見出し本発明に到達し
た。As a result of various studies to solve the above-mentioned problems, the present inventors have found that a feed obtained by adding grain oil to fish meal, which is a commonly used feed, naturally grows, but the flavor and storability of grown adults are not limited to normal fish oil. The present invention has been found to be effective in obtaining a cultured fish that is far superior to the case of addition.
すなわち本発明は脱脂魚粉１００重量部に対して穀物油
脂１〜３０重量部を添加配合した養殖魚用飼料に関す
る。That is, the present invention relates to a feed for cultured fish in which 1 to 30 parts by weight of grain oil and fat is added to 100 parts by weight of defatted fish meal.
本発明において脱脂魚粉としては、いわし、さんま、さ
ば等の通常の飼料に用いられる大衆魚を搾油または溶剤
抽出により、十分に脱脂、乾燥した魚粕の粉末等が挙げ
られる。In the present invention, examples of the defatted fish meal include powders of fish meal that have been sufficiently defatted and dried by squeezing or solvent extraction of popular fish such as sardines, saury, mackerel, etc.
又、穀物油脂としては、米ぬか油、とうもろこし油、小
麦胚芽油及びハトムギ油等を挙げることができる。Examples of grain oils and fats include rice bran oil, corn oil, wheat germ oil, and coix seed oil.
本発明の飼料において脱脂魚粉と穀物油脂の量割合は脱
脂魚粉１００重量部に対して穀物油脂１〜３０重量部、
好ましくは１０〜２０重量部である。１重量部より少な
い場合は栄養価値が小であり、又３０重量部より多いと
嗜好性の点で十分と言えないものとなる。In the feed of the present invention, the proportion of the defatted fish meal and the corn oil and fat is 1 to 30 parts by weight of the corn oil and fat with respect to 100 parts by weight of defatted fish meal
It is preferably 10 to 20 parts by weight. If the amount is less than 1 part by weight, the nutritional value is low, and if the amount is more than 30 parts by weight, the taste is not sufficient.
本発明で用いる穀物油脂はオレイン酸、リノール酸等の
自動酸化に対して安定であり、香味の点でもすぐれた性
質の成分組成を有し、劣化して魚油臭のような不快臭を
発生することが全く無い。The grain fats and oils used in the present invention are stable against autoxidation of oleic acid, linoleic acid, etc., have a component composition with excellent properties in terms of flavor, and deteriorate to generate an unpleasant odor such as fish oil odor. There is no such thing.
単体油脂のよう素価をみると（日本油化学協会編油脂便
覧による） （ウィス法による測定値） 米ぬか油のよう素価 ９９〜１０８ とうもろこし油のよう素価 ８８〜１４７ （通常１１７〜１２３） となっている。Looking at the iodine value of simple oils and fats (according to the Oil and Fats Handbook edited by the Japan Oil Chemistry Association) (measured by the Wis method) iodine value of rice bran oil 99-108 iodine value of corn oil 88-147 (usually 117-123) Has become.
又、うなぎの体油の脂肪酸組成に対応する「よう素価」
の比較をすると、 天然うなぎの体油のよう素価 １０４〜１４２ 従来の養殖うなぎの体油の よう素価 １３５〜１８５ 本発明による米ぬか油による 養殖うなぎの体油のよう素価 １０５± とうもろこし油による 養殖うなぎの体油のよう素価 １１５± である。Also, "iodine value" corresponding to the fatty acid composition of eel body oil
In comparison, the iodine value of natural eel body oil 104-142 the iodine value of conventional cultured eel body oil 135-185 the iodine value of cultured rice eel body oil iodine value of rice bran oil according to the present invention 105 ± corn oil The iodine value of body oil of cultured eel is 115 ±.
そして、この結果は実施例の第１表にも示すとおりであ
り、本発明の飼料が優れたものであることがわかる。The results are also shown in Table 1 of Example, which shows that the feed of the present invention is excellent.
ことほか、米ぬか油は、微量成分として、オリザノール
と称せられる機能性化合物を含有し、米ぬかそのものは
イノシトールをも相当量含有するため、水産飼料として
米ぬかそのものが、特にえび養殖に推奨されているが、
脱脂魚粉と穀物油脂と組合せ養殖魚成長の促進は勿論、
香味が優れ、又日持のよいすぐれた養殖魚を得たのは本
発明者らが初めてなしたものである。従来の魚類の養殖
業界では同種の動物油である魚油の方が適当であると信
じられたことを考えれば本発明は画期的発明である。In addition, rice bran oil contains a functional compound called oryzanol as a trace component, and since rice bran itself also contains a considerable amount of inositol, rice bran itself is recommended for shrimp farming as aquatic feed. ,
In combination with defatted fish meal and cereal oil and fat, of course, promoting the growth of cultured fish,
It is the first time that the present inventors have obtained an excellent cultured fish having an excellent flavor and a long shelf life. The present invention is an epoch-making invention in view of the fact that fish oil, which is the same kind of animal oil, was believed to be more suitable in the conventional fish farming industry.
本発明は養殖魚のいずれの魚の飼料としても有効である
が、特に淡水魚の養殖に好ましく用いられる。INDUSTRIAL APPLICABILITY The present invention is effective as a feed for any cultured fish, but is particularly preferably used for cultivation of freshwater fish.
本発明の飼料は魚粕に日本人の主食として好まれている
米の油脂成分である米ぬか油あるいはとうもろこしの油
等穀物油脂を添加するので、該穀物油脂に含まれている
オレイン酸、リノール酸等の自動酸化に対し安定で且つ
香味の点で優れた性質が生かされ、本発明の飼料は動物
の脂質代謝の原則と合致し、単に養殖魚の成長を促進す
るだけでなく、養殖魚の成体の魚油臭を減少させ、香味
の向上ができ、日持ちをよくし、養殖魚の市場性の向上
を計ることができる。Since the feed of the present invention is added to grain meal such as rice bran oil or corn oil, which is an oil component of rice that is preferred as a staple food for Japanese in fish meal, oleic acid and linoleic acid contained in the grain oil are added. Stable against autoxidation such as, and utilizing the excellent properties in terms of flavor, the feed of the present invention is consistent with the principle of animal lipid metabolism, not only to promote the growth of cultured fish, but also to The smell of fish oil can be reduced, the flavor can be improved, the shelf life can be improved, and the marketability of cultured fish can be improved.
以下に本発明の実施例を説明するが、本発明はこれに限
定されるものではないことは言うまでもない。Examples of the present invention will be described below, but it goes without saying that the present invention is not limited thereto.
〔実施例１〕 次の配合飼料を製造した。[Example 1] The following compounded feed was produced.
脱脂魚粉 １００重量部 米ぬか油 １０重量部 この配合飼料を、うなぎの稚魚（約１００ｇ）に１日３
回与え、８ヶ月間で養殖した。養殖うなぎの成体は約２
５０ｇであった。Defatted fish meal 100 parts by weight Rice bran oil 10 parts by weight This compounded feed is fed to eel fry (about 100 g) 3 times a day.
It was fed once and cultured for 8 months. Adult eels are about 2
It was 50 g.
養殖うなぎ成体の体脂肪の脂肪酸組成は第１表のとおり
である。Table 1 shows the fatty acid composition of the body fat of cultured adult eels.
この養殖うなぎは不快な魚油臭が全くなく、香味が優れ
天然うなぎにも劣らない美味なものであった。This cultured eel had no unpleasant fish oil odor, had a good flavor and was as delicious as a natural eel.
又、蒲焼、白焼等に加工したものの保存性においても通
常の養殖うなぎより優れたものであった。Further, the storability of those processed into kabayaki, shirayaki, etc. was also superior to that of ordinary cultured eels.
〔実施例２〕 実施例１における脱脂魚粉１００重量部に対し、米ぬか
油１０重量部の配合割合をとうもろこし油１０重量部に
置き換えた配合飼料を用い、テラピアを養殖した。 [Example 2] Tilapia was cultivated using a compounded feed in which 10 parts by weight of rice bran oil was replaced with 10 parts by weight of corn oil, relative to 100 parts by weight of defatted fish meal in Example 1.
この場合も成魚の香味、保存性において従来の飼育法に
よるものに比べ優れていることが確認された。Also in this case, it was confirmed that the flavor and storability of the adult fish were superior to those obtained by the conventional breeding method.
本発明の飼料中には穀物油脂が含まれるため、それから
得られる養殖魚は主としてオレイン酸やパルミチン酸等
の低度の不飽和乃至は飽和脂肪酸であるので、香味が優
れ、日持ちが良く、又成長も早いものであり優れた飼料
であるといえる。Since the feed of the present invention contains cereal oils and fats, the cultured fish obtained from them are mainly low-unsaturated or saturated fatty acids such as oleic acid and palmitic acid, and thus have excellent flavor and shelf life, and It can be said that it grows fast and is an excellent feed.
