Abstract

The invention relates to an aquaculture feed. The aquaculture feed comprises 27-30% of protein, wherein the 27-30% of protein comprises 25% of rough protein and 2-5% of refined protein; the rough protein comprises soybean meal, raw soybean meal and cottonseed meal; the refined protein comprises fish meal and silkworm chrysalis meal. The aquaculture feed is low in cost, sufficient in nutrients, environment-friendly and safe.

Description

Aquaculture feed

Technical field

The present invention has about aquaculture, the feed particularly in aquaculture.

Background technology

We know, most of cultured fishes are now mostly that wild species directly enters and propagates artificially, and without the domestication of science, are propagating artificially under condition, forcing it to adapt to the nutrition of artificial breeding environment.When cultivating object and can not adapting to man-made environment, will physiological reaction be produced, even dead.

In aquaculture production practice, feed is most important for cultivation industry.It is not only different types of aquatic species and provides nutrition, and it also affects water quality among long-term existence water body.As wherein contained: the nutritional labeling of protein, fat.

The disease of common aquaculture, usually be because forage compounding is not appropriate in breeding process substantially by simply thinking, lacking or the reason such as being wanting in consideration to feeding habits conversion in each cultivation stage of trace element, causes fish physiological maladies, as fatty liver, stiff flat disease etc.

It is excessive that this is wherein mainly manifested in daily ration, feeding quantity in cultivation; Or directly use grouts, chilled nursing, superfluous residual feed becomes expensive fertilizer; In addition fish, a large amount of excremental accumulation of shrimp, too high breeding density and excessive fertilising are all the major reasons causing inorganic salt concentration in water body higher.

How to ensure the nutrition of fish, avoid again waste and polluted-water, its problem mainly considered comprises: the actual cultivation, utilizing status etc. of protein quality quantity, amino acid whose counterbalance effect and selected protein raw material.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of aquaculture feed, the protein content in described feed is 27 ~ 30%, comprising: content is the thick protein of 25%, and content is the protamine matter of 2 ~ 5%; Described thick protein comprises: Soybean Meal, bredsoy and Cottonseed Meal; Described protamine matter comprises: fish meal and dried silkworm chrysalis meal.

The normal growth nutrition that aquaculture feed cost provided by the present invention is low, ensure that fish, be conducive to purifying water body, due to the eutrophication algae that the materials such as feed cause in dewatering side by side, ensure the oxygen content in water, reduce the probability of viral communication.

Detailed description of the invention

The invention provides a kind of aquaculture feed, the protein content in described feed is 27 ~ 30%, comprising: content is the thick protein of 25%, and content is the protamine matter of 2 ~ 5%; Described thick protein comprises: Soybean Meal, bredsoy and Cottonseed Meal; Described protamine matter comprises: fish meal and dried silkworm chrysalis meal.

This feed is while guarantee nutriment, nitrate and hydrogen sulfide material in water quality should be reduced, avoid the eutrophication harmful substance because the materials such as feed cause, and the water body that inorganic salts cause is muddy, algal bloom, also make water oxygen gas decline, the probability of viral communication such as to increase at the harm.

In the present invention, the protein content of feed is 27 ~ 30%, and it can meet the growth needs of overwhelming majority cultivation.Meanwhile, its content is the thick protein of 25%, and content be 2 ~ 5% protamine matter there is stronger low-cost advantage.

Particularly described thick protein comprises: Soybean Meal, bredsoy and Cottonseed Meal; Described protamine matter comprises: while fish meal and dried silkworm chrysalis meal ensure that low cost, also reduces the generation of the generation of harmful nitrogen oxygen compound, harmful inorganic salts, ensures the clean of water body.

As the preferred embodiments of the present invention, described Soybean Meal, the mass ratio of bredsoy and Cottonseed Meal is 1:1.5:2.The feature that it has low cost, hazardous substance lowers.

Meanwhile, as the further improvement of the present embodiment, described thick protein also comprises: sesame seed meal and rapeseed dregs.Be 1:1 as preferred its mass ratio.This formula provides supplementing of fat content while can ensureing protein, be conducive to fish growth.

As further embodiment of the present invention, the mass ratio of described fish meal and dried silkworm chrysalis meal is 1:0.3 ~ 0.5.While reducing the cost, be convenient to the generation of digesting and assimilating, avoiding harmful nitrogen oxygen compound of feed.

Feed provided by the present invention, while providing abundant nutrition, to avoid in water quality inorganic salts to produce, and is conducive to the daily routines of aquaculture product and reduces the probability of viral communication, the supply of forage of suitable especially freshwater fish.

Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments is described as just example.The protection domain of the essence that the application will require more is embodied in the scope that independent claims provide, and its dependent claims.
