The present invention relates to a feed for young fish, particularly a feed for young fish with high protein efficiency. Conventionally, feed for young fish has been required to have a high crude protein content in order to speed up the growth of young fish. However, it is generally believed that as the crude protein content in feed increases, the protein efficiency decreases relatively (see Reikichi Ogino (ed.), "Nutrition and feed for fish" and Yoshiro Hashimoto (ed.), "Fish culture feed science"). It was believed that there was no feed that could simultaneously satisfy both an increase in protein efficiency and high protein efficiency. In the process of researching feed for young fish, the present inventors used fish meal as the main ingredient with a particle size of 150μ or less and a crude protein content of 70 to 80% by weight, and found that the crude protein content was surprisingly high. It has been found that a feed with relatively high protein efficiency can be obtained even if the feed is digested and absorbed well, making it possible to keep the fish tank clean at all times and, in turn, maintain a high survival rate of young fish. That is, the present invention is a feed for young fish whose main component is fishmeal having a particle size of 150 μm or less and a crude protein content of 70 to 80% by weight. The fishmeal used in the present invention is obtained by classifying, for example, commercially available fishmeal with a low crude protein content (approximately 55 to 68%) and pulverized products thereof, preferably using an air classifier, to determine the particle size.
It is obtained by collecting the fraction of 150μ or less. In the present invention, the thus obtained fishmeal having a particle size of 150μ or less and a crude protein content of 70 to 80% is used, and the crude protein content is preferably about 35% or more of the total feed, preferably 40 to 80%.
% or more. In addition to this fishmeal, the crude protein content of the feed can also be increased by using wheat flour or other protein-containing raw materials. The fish meal is mixed with appropriate amounts of starch, vitamins, minerals, and other ingredients commonly used as feed materials for young fish, and then formed into dough, crumbles, pellets, etc. to obtain the product of the present invention. In addition, this feed for young fish is suitable for, for example, sweetfish, rainbow trout,
Suitable for raising eel, carp and yellowtail. Even though the feed for young fish of the present invention has a high crude protein content, it has a relatively high protein efficiency compared to feeds that use conventional fishmeal.Furthermore, because it is easily digested and absorbed, the fish tank is kept clean at all times. It is possible to maintain a high survival rate of young fish, and the feed efficiency is superior to that of conventional feeds. Furthermore, since the feed for young fish of the present invention uses fishmeal with a high crude protein content, it is possible to obtain molded products containing a high crude protein content of 65% or more, which cannot be molded with conventional feeds using fishmeal. Examples of the present invention will be described below. Example 1 100 kg of northern sea fish meal (crude protein content 66%) was collected using an air classifier (Turbo Classifier TC-15N, manufactured by Nisshin Engineering Co., Ltd.) at an air flow rate of 2.8 m 3 /min.
The fish was classified under the conditions of 800 rpm to obtain 32 kg of fishmeal (crude protein content 73%) with a particle size of 150μ or less. The obtained fishmeal, wheat flour (crude protein content: 17%), and a vitamin/mineral mixture were mixed in the proportions shown in Table 1, and then formed into pellets by a conventional method to obtain feed for juvenile rainbow trout. For comparison, pellets were manufactured using the same raw materials as above in the proportions shown in Table 1, except that end-class Northern Sea fishmeal (crude protein content 66%) was used instead of fishmeal with a particle size of 150μ or less. crushed to a particle size of 0.2 to 1.0 mm
It was made into a crumble. Table 2 shows the results of feeding these crumbles to juvenile rainbow trout for 40 days.

The fish meal was classified under the condition of 1550 rpm to obtain 20 kg of fishmeal (crude protein content 78%) with a particle size of 60 to 150 μm. The obtained fishmeal, cornstarch, pregelatinized potato starch, and vitamin/mineral mixture were used in the proportions shown in Table 3, and feed oil and an appropriate amount of water were added to obtain a feed for young eel as a paste. For comparison, we used the same raw materials as above in the proportions shown in Table 3, except that unclassified northern sea fishmeal (crude protein content 68%) was used instead of fishmeal with a particle size of 60 to 150μ or less. was manufactured. Table 4 shows the results of feeding these baits to eel fry for 65 days.

The obtained fishmeal and flour (crude protein content 16%),
Cornstarch and a vitamin/mineral mixture were mixed in the proportions shown in Table 5, and then formed into pellets by a conventional method to obtain feed for carp fry.

Table 6 shows the results of feeding these pellets to carp fry for 35 days.
