Abstract

The invention discloses a freshwater shrimp breeding method. Feed used in the freshwater shrimp farming method is prepared from the following raw materials in part by weight: 35-40 parts of wheat bran, 25-35 parts of peanut cake, 24-32 parts of fish powder, 1-2 parts of clam shell powder and 2-3 parts of composite bean dreg powder, wherein a preparation method of the composite bean dreg powder comprises the following steps: drying 8-10 parts of fresh bean dregs; milling to obtain bean dreg powder for use; uniformly mixing 0.1-0.3 part of Stellaria yunnanensis, 2-4 parts of Chinese wolfberry, 3-5 parts of Atractylodes, 1-2 parts of Pseudostellaria heterophylla and 3-5 parts of Codonopsis; adding water which is 3-5 times of the total weight of raw materials; decocting and removing residues to obtain Chinese herbal extract; finally, uniformly mixing the bean dreg powder and the Chinese herbal extract, homogenizing and performing spray drying to obtain composite bean dreg powder. The freshwater shrimp farming method has the benefits as follows: according to the characteristics of freshwater shrimp farming, a farming environment is reasonably selected; the feed according to the characteristics of freshwater shrimps is used, so that the disease resistance is high, digestion and absorption are improved, and the growth is promoted.

Description

The cultural method of a kind of freshwater shrimp

Technical field

The present invention relates to the shrimp culture field, exactly is the cultural method of a kind of freshwater shrimp.

Background technology

The freshwater shrimp meat flavour is delicious, and is nutritious, is subject to consumer's extensive welcome.Existing shrimp culture technology is single, shrimp culture industry slower development.

Summary of the invention

The object of the invention is to overcome the defective of video memory, the cultural method of a kind of good in economic efficiency freshwater shrimp is provided.

Above-mentioned purpose realizes by following scheme:

The cultural method of a kind of freshwater shrimp is characterized in that:, may further comprise the steps:

(1) selection in pond and sterilization selection area are 12-15 mu, and the degree of depth is the pond of 1-1.3 rice, and the shrimp seedling is put in a suitable place to breed front to the pond lime disinfection;

(2) the shrimp seedling was put in a suitable place to breed and put shrimp seedling 16-18kg/ mu in a suitable place to breed before-25 days on the 17th February;

(3) the described feed of the preparation of feed is made by the raw material of following weight parts: wheat bran 35-40, groundnut cake 25-35, fish meal 24-32, shell powder 1-2, composite bean ground-slag 2-3;

The preparation method of described composite bean ground-slag is: after the fresh bean dregs of 8-10 weight portion are dried, abrasive dust, get okara powder for subsequent use, with 0.1-0.3 weight portion yunnan starwort root, 2-4 weight portion der Bockdorn, the 3-5 weight portion bighead atractylodes rhizome, 1-2 weight portion rod rod grass, 3-5 weight portion Radix Codonopsis mixing, add again and be equivalent to raw material gross weight 3-5 times water again, after decocting removes slag, get Chinese medicine extract, at last with okara powder, Chinese medicine extract mixing, homogeneous, atomized drying, and get final product;

(4) every day thrown something and fed twice by the feed of throwing something and feeding of feed, be respectively morning the 8-9 point and afternoon the 17-18 point, feeding volume is the 3-5% of shrimp body gross weight;

(5) regulating and controlling water quality was used alternatingly bacillus subtilis formulation and EM microbial inoculum regulating water quality every 8-10 days, and wherein the bacillus subtilis formulation consumption is 130-160g/ mu, and EM microbial inoculum consumption is 70-90g/ mu;

(6) becoming shrimp to be fished in the 6-7 month fishes for the one-tenth shrimp.

The cultural method of described a kind of freshwater shrimp is characterized in that: the preparation method of described feed is: by weight behind the mixing, sterilization behind the mist projection granulating, and get final product with raw material.

Beneficial effect of the present invention is: the present invention is directed to the shrimp culture characteristics, reasonably select breeding environment, use the feed for the freshwater shrimp characteristics, resistance against diseases is good, and raising is digested and assimilated, and promotes the effect of growth.

Embodiment

The cultural method of a kind of freshwater shrimp may further comprise the steps:

(1) selection in pond and sterilization selection area are 15 mu, and the degree of depth is 1.2 meters pond, and the shrimp seedling is put in a suitable place to breed front to the pond lime disinfection;

(2) the shrimp seedling was put in a suitable place to breed and put shrimp seedling 18kg/ mu in a suitable place to breed before February 20;

(3) the described feed of the preparation of feed is made by the raw material of following weight parts (kg): wheat bran 40, groundnut cake 30, fish meal 30, shell powder 2, composite bean ground-slag 3;

The preparation method of described composite bean ground-slag is: after the fresh bean dregs of 10 weight portions are dried, abrasive dust, get okara powder for subsequent use, with 0.3 weight portion yunnan starwort root, 4 weight portion der Bockdorns, the 5 weight portion bighead atractylodes rhizomes, 2 weight portions rod rod grass, 3 weight portion Radix Codonopsis mixings, add again the water that is equivalent to 5 times of raw material gross weights again, after decocting removes slag, get Chinese medicine extract, at last with okara powder, Chinese medicine extract mixing, homogeneous, atomized drying, and get final product;

(4) every day thrown something and fed twice by the feed of throwing something and feeding of feed, is respectively 9 of mornings and point in afternoons 18, and feeding volume is 5% of shrimp body gross weight;

(5) regulating and controlling water quality was used alternatingly bacillus subtilis formulation and EM microbial inoculum regulating water quality every 10 days, and wherein the bacillus subtilis formulation consumption is 150g/ mu, and EM microbial inoculum consumption is 90g/ mu;

(6) becoming shrimp to be fished for June 18 fishes for the one-tenth shrimp.

The preparation method of described feed is: by weight behind the mixing, sterilization behind the mist projection granulating, and get final product with raw material.

The average output freshwater shrimp of the present embodiment 100.3kg, average feed coefficient is 1.75.
