Embodiment 1

[0036] The preparation of embodiment 1 modified saponite powder

[0037] (1) Take the raw soapstone ore, carry out high-speed impact crushing, then use a cyclone to classify and remove impurities, add purified water to carry out wet flotation, after standing for 24 hours, remove the supernatant and sediment, take the middle layer to dry, and Pulverize again in a high-speed vortex mill to obtain raw saponite powder;

[0038] (2) adding purified water to the former powder of soapstone powder obtained in step (1), making the weight concentration is 2% (m / v) suspension, ultrasonic treatment 25min, then sealed in a high-pressure steam boiler, in Treat at 180°C for 10 hours, cool to room temperature, centrifuge to collect the precipitate, wash twice with deionized water and absolute ethanol, and dry in vacuum at 80°C for 6 hours to obtain hollow microspheres;

[0039] (3) Disperse the hollow microspheres prepared in step (2) in water, add polyarginine, the weight ratio of the hollo...

Embodiment 2

[0040] The preparation of embodiment 2 fermentation residue mixture

[0041] Weigh 10kg of soybean powder, 10kg of peanut meal, 10kg of garlic powder and 10kg of Trichosanthes powder, mix them evenly, place them in a fermenter, add water to adjust the water content of the dry material to 60%, adjust with 1% calcium hydroxide pH to 6.0, add 5% (m / m) of the total weight of the dry material mixed bacteria, the mixed bacteria are composed of Candida utilis, Aspergillus niger and Rhizopus oligosporus in a weight ratio of 1:0.5:0.1 , fermented at 28°C for 24 hours under ventilated conditions, dried the fermented product, cooled to room temperature, pulverized, and passed through a 100-mesh sieve to obtain a fermented residue mixture.

Embodiment 3-5 and comparative example 1-3

[0042] The preparation of embodiment 3-5 and comparative example 1-3 rice fragrant grass carp breeding feed

[0043] The composition of the embodiment of the present invention 3-5 and comparative example 1-3 rice fragrant grass carp breeding feed is shown in the following table (all are percentage by weight or weight ratio):

[0044]

[0045]

[0046] The modified saponite powder in the above table is obtained in Example 1, and the fermented slag mixture is obtained in Example 2. Wherein, the modified saponite powder in Comparative Example 1 is replaced by the former powder of saponite obtained in Example 1 step (1); the modified saponite powder in Comparative Example 2 is replaced by Example 1 step (2) to obtain hollow microspheres; In Comparative Example 3, the modified soapstone powder prepared by the present invention was not added, and the ratio of other components was increased accordingly.

Abstract

The invention relates to a feed for culturing rice-fragrance grass carps, and a culturing method of the rice-fragrance grass carps. The feed comprises the following components in weight percentage: 20-30% of algae powder granules, 10-15% of modified soapstone powder, 1-3% of micronutrients, 10-20% of an adhesive, and 40-50% of a mixture of fermented dregs. The feed and the culturing method provided by the invention are adopted to feed the grass carps for 6 months, and the survival rate of the grass carps reaches 100%, and the multiple of weight gaining is 11.07-12.16. Detection indicates that the harvested grass carps are high in protein content, low in fat content, and delicious in meat quality; and meanwhile, in intestinal tracts of the grass carps, the contents of pathogenetic bacteria easily causing enterogastritis are lowered, wherein the pathogenetic bacteria comprise aeromonas hydrophila, aeromonas punctata f. intestinalis, aeromonas caviae, escherichia coli and enterococci, and the contents of probiotics such as lactobacillus and bifidobacteria are increased, so that the risk of enterogastritis occurrence among the grass carps is effectively decreased.

Description

technical field [0001] The invention relates to a method for cultivating fish, in particular to a feed for cultivating rice carp and a cultivating method thereof. Background technique [0002] my country is a big fish farming country in the world, and it is also the country with the earliest development of freshwater fish in the world. Among them, grass carp (grass carp) is one of the unique "four major fishes" in my country. It is a common species of freshwater fish. It is rich in nutrients, high in protein content, and has the characteristics of fast growth, strong adaptability and high yield. It is one of the favorite breeds of farmers. At present, grass carp occupies a considerable proportion in my country's freshwater fish farming, and is the cultured species with the largest production and consumption in the world. [0003] Grass carp is a large herbivorous fish. It generally moves in the middle and lower layers of the water layer, and sometimes goes to the upper laye...
