い。2. Description of the Related Art In recent years, the development of aquaculture has been remarkable, and a large number of larvae of various fishes, regardless of their terrestrial water or seawater, have been successfully produced and bred, and the number of them has been increasing year by year. Along with this, the development of artificial mixed feed for seedling production and cultivation of cultured fish and shellfish has been carried out, and has already been put to practical use in red sea bream, flounder, sweetfish, prawns and the like. However, there are still many problems in fish nutrition, and the vitality of larvae cultivated by using these artificial mixed feeds at the time of seedling production and rearing is low, and the survival rate and growth rate of larvae are low. It cannot withstand the mass production of farmed fish.

見出した。Means for Solving the Problems As a result of earnest research for the improvement of the present inventors,
We found that proline, which is biosynthesized from glutamic acid in fish, does not meet the requirement during the course of biosynthesis. Proline is derived from feed ingredients and is normally 1.5 to 2.0 in feed.
However, even if this feed is given to fry just after hatching, the vigor of the fry will be low and the growth will be poor. It is considered that this poor growth is due to the inability to fully utilize the proline in the feed, and at the same time, to the failure to keep up with the biosynthetic supply of glutamic acid. Therefore, it has been found that this problem can be solved by supplying the lacking proline in a free form.
以下に本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail.
本発明は遊離のプロリンを0.05％（w/w）以上の割合
で人工配合飼料に含有させてなる養魚用飼料に関する。The present invention relates to a feed for fish farming, which comprises free proline in an artificial blended feed in a proportion of 0.05% (w / w) or more.

長促進効果を得ることができる。According to the present invention, by adding proline to an ordinary artificial mixed feed and administering it to fish, it is possible to improve the vitality of the fish and obtain a growth promoting effect.
