Abstract

PURPOSE:To obtain a feed for marine products by blending a feed for marine products with a brown alga and zeolite, thereby, having synergistically physiologically activating effects of each components, showing greatly excellent growth promotion, improvement in feed demanding ratio, etc., exhibiting improving effects on increase in pathogenic resistance, progress of health, improvement in multiplication and physiology, when compared with the case where a brown alga and zeolite are not used. CONSTITUTION:A feed for marine products comprising brown alga and zeolite as essential components. The blending ratio of the essential components differs depending upon fishes and shellfishes as a target and is generally 9:1-1:9, preferably 5:5 to give good results. Especially in summer when temperature of the sea is raised, the blending ratio of zeolite is preferably increased with respect to contamination of environment resulting from adsorption of gas such as ammonia in body, excrement of fish deposited on the bottom of culture zone and decomposition of remaining feed. In the case of young fish, increase in blending ratio of marine algae provides excellent results.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed for marine products, and more particularly to a feed for activating the physiology of edible aquatic animals such as seafood and improving the productivity in aquaculture thereof.

[0002]

BACKGROUND OF THE INVENTION Brown algae are rich in iodine and promote the production of thyroid hormone in livestock or poultry, activate the cells of the whole body, enhance the function of various organs, secrete various hormones in endocrine organs. It is used as a feed additive in order to produce a regulating action and a metabolism promoting action of various nutritional substances. Zeolite is also used as an additive component of feed because its excellent adsorption ability and cation exchange ability enhance the function of digestive organs of livestock or poultry, and antacid action of aluminum silicate as a main component.

The present inventor has previously found that by using these brown algae and zeolite in combination, the effects of the two are synergized, and in particular, a feed useful for livestock or poultry can be obtained, and a patent application has already been applied. Yes (Tokuhei 3-034
903).

[0004] After further research, even though animals such as livestock differ in physiological function, surprisingly, when brown algae and zeolite are used in combination, the physiology is also activated in seafood and the like, and aquaculture is performed. The present invention has been completed by finding out that it will be a feed for marine products that can improve the productivity in.

[0005]

The present invention provides a feed for marine products characterized by containing brown algae and zeolite as essential components. In the present specification, the term "feed" means:
This includes not only feeds directly eaten by seafood and the like, but also so-called feed additives that are used by mixing with other feed ingredients to constitute such feeds.

[0006] The brown alga used is not particularly limited in kind, origin and the like, and may be any seaweed belonging to the brown alga. Generally, brown algae is washed well with water, dried, pulverized and used as a powder.
It is preferable that the grain size be about 14 mesh.

[0007] Zeolite is not particularly limited in kind, origin, etc., and may be any of those usually used for feed. Also for zeolite, it is preferable to use powder having a particle size of about 350 to 20 mesh.

In the aquatic feed of the present invention, these brown algae and zeolite are mixed and used. The mixing ratio is
The weight ratio of brown algae: zeolite is generally 9: 1 to 1: 9, preferably 5: 5, although it depends on the target seafood.
Good results are obtained in the range. In particular, in the summer when the water temperature rises, it is desirable to increase the mixing ratio of zeolite from the viewpoints of environmental pollution due to the adsorption of gases such as ammonia in the body and the fecal matter accumulated at the bottom of the aquaculture area, and the decay of residual food. .. In the case of juvenile fish, good results can be obtained by increasing the mixing ratio of seaweed.

The aquatic feed of the present invention can be produced by a conventional method. For example, brown algae powder and zeolite can be mixed in a desired ratio by a conventional method to give a powdered feed. Further, molasses, brewer's yeast, calcium, and other feed ingredients can be appropriately mixed therewith, and pelletization and the like may be performed by a conventional method. In addition, it may be mixed with live feed or other mixed feed for the purpose of adjusting the dispersibility in water, the sedimentation rate, and the like.

The marine feed of the present invention is, for example, flounder,
As a feed for saltwater fish such as troughs, freshwater fish such as amago, yamame, char, shellfish such as clams, shellfish such as shrimp and crabs, and other edible seafood such as turtles.
Alternatively, it is used as an additive thereof and is generally used as a mixture of brown algae and zeolite in a proportion of about 1 to 10% by weight of the total feed, although it depends on the target seafood or the like. Usually, the feed to be fed may be produced by adding the aquatic feed of the present invention to moist pellets, which is a mixture of a raw feed and a compounded feed, in order to adjust the sedimentation speed and avoid the feed loss due to the tidal current in the open sea. preferable.

[0011]

The present invention will be described in more detail with reference to examples, but the invention is not limited thereto. Example 1 50 parts by weight of brown algae powder (120 mesh powder of Norwegian brown algae sold by Shinkyo Sangyo Co., Ltd. under the trade name of Argit in Norway) and zeolite (Shinkyo Sangyo Co., Ltd.)
Further, 50 parts by weight of 325 mesh powder of Zeolite from Shimane Prefecture, which is commercially available under the trade name of Shinkyolite, was well mixed according to a conventional method to obtain the marine feed of the present invention.

INDUSTRIAL APPLICABILITY According to the present invention, the combined use of brown algae and zeolite synergizes the physiological activation effect of each, and is extremely excellent in growth promotion and feed compared to the case of feeding alone. It shows the improvement of the request rate, etc., and also has the effect of improving antipathogenicity, promoting health, and improving reproductive physiology.
Furthermore, brown algae exhibit a binder effect, an antioxidant effect, a freezing and burn preventive effect, etc. on a live feed, and an excellent aquatic feed can be obtained.
