Example Embodiment

[0022] Example 1

[0023] The breeding method for increasing the weight of blue crabs includes the following preparation steps: take the conventional blue crab special feed and crush it to 200 mesh, then mix it with 1.2% of the traditional blue crab special feed by weight of Chinese medicine additives, granulate, and proceed according to the conventional method. Just feed the blue crabs.

[0024] The traditional Chinese medicine additive is made from the following raw materials in parts by weight: 22 parts of Hovenia dulcis, 28 parts of ground peach blossoms, and 5 parts of amaranth.

[0025] The method for preparing the traditional Chinese medicine additive is: take all the raw materials of the traditional Chinese medicine additive, pulverize to 100 mesh, add water 16 times the weight of the total raw materials, reflux and extract three times at 70°C for 30 minutes each time, combine the extracts and spray dry.

Example Embodiment

[0026] Example 2

[0027] The breeding method for increasing the body weight of blue crabs includes the following preparation steps: take the conventional blue crab special feed and crush it to 250 mesh, then mix it with 0.7% of the traditional blue crab special feed by weight of traditional Chinese medicine additives, granulate, and proceed according to the conventional method. Just feed the blue crabs.

[0028] The traditional Chinese medicine additive is made of the following raw materials in parts by weight: 30 parts of Hovenia dulcis, 19 parts of ground peach blossoms, and 11 parts of amaranth.

[0029] The preparation method of the traditional Chinese medicine additive is: take all the raw materials of the traditional Chinese medicine additive, pulverize to 150 mesh, add water 12 times the weight of the total raw material, reflux and extract three times at 80°C for 30 minutes each time, combine the extracts, and spray dry.

[0030] Example 3

[0031] The breeding method for increasing the body weight of blue crabs includes the following preparation steps: take the conventional blue crab special feed and crush it to 300 meshes, then mix it with 0.3% of the traditional blue crab special feed weight and the traditional Chinese medicine additive uniformly, granulate, and proceed according to the conventional method. Just feed the blue crabs.

[0032] The traditional Chinese medicine additive is made of the following raw materials in parts by weight: 38 parts of Hovenia dulcis, 10 parts of ground peach blossom, and 17 parts of amaranth.

[0033] The method for preparing the traditional Chinese medicine additive is: take all the raw materials of the traditional Chinese medicine additive, pulverize to 200 mesh, add water 8 times the weight of the total raw materials, reflux and extract three times at 90°C for 30 minutes each time, combine the extracts and spray dry.

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a breeding method for increasing the blue crab weight. The method comprises the following steps that conventional feed special for blue crabs is crushed to be 200-300 mesh and then mixed with traditional Chinese medicine additives to be uniform, granulation is conducted, and the blue crabs are fed through a conventional method; the dosage of the traditional Chinese medicine additives is 0.3%-1.2% of the weight of the conventional feed special for the blue crabs; the traditional Chinese medicine additives are prepared from, by weight, 22-38 parts of hovenia dulcis thunb, 10-28 parts of herba urenae lobatae and 5-17 parts of spiny amarauth herbs or roots. Accordingly, by simply adding the traditional Chinese medicine additives prepared from the hovenia dulcis thunb, the herba urenae lobatae and the spiny amarauth herbs or roots in the conventional feed special for the blue crabs, and by means of thesynergistic effect, the weight of the blue crabs can be increased, the economic benefit is increased, the hovenia dulcis thunb, the herba urenae lobatae and the spiny amarauth herbs or roots are sweetand light, the palatability of the feed cannot be affected, and the feed is natural, green and safe.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a breeding method for increasing the body weight of mud crabs. Background technique [0002] The genus Scylla belongs to the class Crustacea, order Decapoda, suborder Brachyura, and family Portunidae. Distributed in sea areas such as Southeast Asia, Australia, Japan, India, and South Africa, and in coastal waters of Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, and Hainan in my country. Because of its huge size, fast growth, delicious meat, and rich nutrition, it is regarded as a precious seafood in modern and modern times, and it is also an important marine economic species for artificial breeding in coastal areas. With regard to the understanding of the distinction between species of the genus Scylla, many scholars support that the genus Scylla has a common Scylla paramamosain (Latin name: Scylla paramamosain), Scylla serrata (Scyllaserrata), Scyllatranquebaric...
