Problems solved by technology

[0003] If we develop according to the current model, once the situation is reversed, under such an ultra-high density and such an extensive model, the ecology will not be able to bear it, which will lead to stagnant growth of crayfish, aggravated lesions, reduced survival rate, and loss of input costs
It will have an adverse impact on the development of the industry, put pressure on the society, and may even cause many breeding bases with an area of ​​more than 500 mu to continue to lose money and owe debts. Thousands of households have no one to pay the contract payment after the land is transferred, leaving future troubles for the local government. , endangering social stability

Embodiment 1

[0024] see figure 1 , figure 2 and image 3 , a culture method for cultivating and separating crayfish in paddy fields, comprising the steps of:

[0025] S1: Select the breeding area, excavate ditches in the breeding area as the nursery area 1 for crayfish, and excavate the area within the slope 3 in the ditch as a ridge to form the growing area 2 for crayfish, where the nursery The area ratio of area 1 and growing area 2 is 1:9; the ratio of nursery area 1 and growing area 2 is based on the grasp of seasonal climate characteristics, and is mainly due to the characteristics and needs of actual production.

[0026] S2: Carry out crayfish seedlings in nursery area 1, and when the size of the first batch of shrimp seedlings in nursery area 1 reaches 150-200 tails / catties, grow them at a rate of 30-40 catties / mu before Qingming The first batch of seedlings in zone 2; before Qingming is the stage with the highest survival rate, fastest growth and least disease; this period has t...

Embodiment 2

[0036] see figure 1 , figure 2 and image 3 , a culture method for cultivating and separating crayfish in paddy fields, comprising the steps of:

[0037]S1: Select the breeding area, excavate ditches in the breeding area as the nursery area 1 for crayfish, and excavate the area within the slope 3 in the ditch as a ridge to form the growing area 2 for crayfish, where the nursery The area ratio of area 1 to growing area 2 is 1:9.

[0038] S2: When the size of the first batch of shrimp seedlings in nursery area 1 reaches 150-200 tails / catties, the first batch of seedlings in grow-up area 2 will be thrown at 30-40 catties / mu before Qingming; before Qingming It is the stage with the highest survival rate, the fastest growth and the least disease of shrimp seedlings; this period has the highest doubling rate of seedlings, and the success rate of breeding is also high; the number of seedlings thrown at 30-40 catties / mu is used for the second stage of growing area 2. A batch of see...

Abstract

The invention relates to the technical field of crayfish breeding and discloses a breeding method of rice field crayfish cultivation-breeding separation. A breeding mode of cultivation-breeding separation is adopted, larvae cultivation is performed in a larvae cultivation area to provide larvae for a breeding area; precise release and density control are performed in the breeding area, so that controllable production is realized, growth vigor is improved, specification is ensured, high price is realized, economic benefit is gained, ecological pressure is relieved, disease death is reduced, input use is reduced, and food safety and ecological safety are ensured and promoted; adult crayfishes in the breeding area are caught subsequently to supplement parents of the larvae cultivation area, so that function separation, production linkage, mutual promotion, cyclic breeding and sustainable management are realized.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a cultivation method for rearing and separating crayfish in paddy fields. Background technique [0002] Crayfish farming has developed to this day, and the expansion period is coming to an end. The model of selling seedlings to convert super-high density into currency and wealth and reduce ecological pressure is no longer sustainable. [0003] If it develops according to the current model, once the situation is reversed, under such an ultra-high density and such an extensive model, the ecology will not be able to bear it, which will lead to stagnant growth of crayfish, aggravated lesions, reduced survival rate, and loss of input costs. It will have an adverse impact on the development of the industry, put pressure on the society, and may even cause many breeding bases with an area of ​​more than 500 mu to continue to lose money and owe debts. Thousands of households ...
