急速に普及しつつある。(Conventional technology and its problems) In recent years, the environment surrounding Japan's fishing industry has become even more severe, and fishing grounds have become significantly narrower due to international restrictions such as economic zones. For this reason, the number of fish cultivated through marine aquaculture is rapidly increasing, and marine aquaculture of sea bream, yellowtail, flounder, horse mackerel, pufferfish, coho salmon, etc. is becoming popular. However, currently, the feed in marine aquaculture is fed fresh and frozen fish such as sardines and mackerel, which are often caught fish, in the form of minced, cut, or rounded fish, which prevents water-soluble nutrients from leaching into seawater. There is a problem that fish predation rate is low because there are a lot of them and they are often scattered in the seawater shell. For this reason, recently fishmeal, flour, oil cake,
Fish feed (hereinafter referred to as Moinutverev), which is made by mixing and stirring vitamins, minerals, and other fish feed ingredients with a binder, and then kneading and molding the feed with ecologically ground material to form granules, is rapidly becoming popular. .

。Ben 1. It is a nutritionally and pathologically calculated scientific feed that combines nutrients such as vitamins and minerals with fishmeal, flour, and fish meal, and it is also possible to uniformly mix therapeutic drugs. Until now, as a binder for moist pellets,
The use of water-soluble polymers such as carboquine methylcellulose alkali metal salt (sodium carboxymethylcellulose is usually used) and sodium alginate is described in Japanese Patent Publication No. 13773/1983.

至った。(Means for Solving the Problems) As a result of intensive studies to improve these problems, the present inventor found that the degree of carboxymethyl group substitution per anhydroglucose unit is 0.45 to α70 in fish feed raw materials. Yes, the viscosity of a 1% aqueous solution is 2.0000 PS or more at 25°C, 1
When a mixture obtained by blending carboxymethyl cellulose alkali metal salt (hereinafter abbreviated as CMC) as a binder with 5,000 CPS or less is kneaded and molded and granulated, it shows extremely good extrusion workability and the obtained The moist pellets were in good condition with no stickiness and no fusion. Furthermore, as a result of feeding moist pellets using the binder of the present invention in seawater, it was found that there was no elution of water-soluble nutrients into the seawater, and the floatability was excellent, resulting in less marine pollution.To complete the present invention. It's arrived.

る。Examples of fish feed raw materials here include fish meal, wheat flour, oil cake, vitamins, minerals, other fish feed raw materials, and crushed live feed such as raw fish and frozen fish. Further, CMC having a DS of 0.45 to α70 and a 1% aqueous solution having a viscosity of λOOOCPS or more at 25° C. is used as a binder. If the DS is less than α45, the water utilization capacity of CMC will be poor and the solubility will be poor. Furthermore, if the DS exceeds 0.70, the water absorbency will be poor and a sticky coating will appear. Furthermore, the viscosity of a 1% by weight aqueous solution at 25°C is 2. If it is less than OOOCPS, the cohesive strength will be poor.
Since the moist pellets are sticky and soft, the pellets fuse together after granulation, causing problems in feeding operations. Furthermore, although there is no need to specify an upper limit for the viscosity, ``in manufacturing terms, the viscosity of a 1% by weight aqueous solution is considered to be approximately 15,000 CPS at 25°C.
