Cherax quadricarinatus rice self-breeding method

Abstract

The invention belongs to the technical field of aquaculture, and discloses a cherax quadricarinatus rice self-breeding method. The method comprises the steps of selecting a rice field suitable for rice and shrimp comprehensive breeding, wherein the rice field is provided with a 2-4 m wide and 0.8-1.2 m deep shrimp ditch; arranging an enclosure culture ditch, adopting an anti-escape net at the periphery, building an anti-escape facility, and isolating the enclosure culture ditch by means of the anti-escape net on the basis that the area ratio is 2:1-3:1; performing parent shrimp stocking, wherein female shrimp and male shrimp are stocked at the isolation region; performing offspring seed self-breeding, removing a sandbag and isolating the anti-escape net during the parent fish self-breedingperiod, and performing mating self-breeding on parent fish, wherein produced shrimp seeds penetrate through the anti-escape net and enter the rice field for natural growth. The culture parent shrimpis used for performing self-breeding, no shrimp seed needs to be purchased, the production cost is effectively lowered, and the rice field comprehensive breeding benefits are improved; the shrimp seedobtained after self-breeding penetrates through the anti-escape net for natural growth, damage to the shrimp seed during transportation and moving is avoided, and the shrimp seed survival rate is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a paddy field self-propagating method for red-clawed crayfish. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The world's agricultural production is facing increasing food demand, shortage of water and soil resources, and food security issues in response to climate change. Modern intensive food production uses a large amount of pesticides and fertilizers, which not only increases the cost of agricultural production, but also causes soil compaction, pesticide residues and environmental pollution. Aquaculture is an important source of protein food for humans, but large-scale farming has also caused environmental pollution. Research at home and abroad has shown that agriculture that combines aquaculture with agricultural systems is an effective way to promote sustainable agricultural develo...

AI Technical Summary

Problems solved by technology

[0006] In summary, the existing problems in the prior art are: in the prior art, due to the increasing number of cultivators preparing to raise red-clawed crayfish all over the country, the supply of seedlings is far from meeting the demand, and even some still need to be transferred from abroad. progress, resulting in increased costs and increased risk of farming

[0008] At present, there is no report on the self-propagation method of red-clawed crayfish in rice fields. The self-propagation method of red-clawed crayfish in paddy fields involves many technical details such as selection of rice fields, setting of enclosure ditch, stocking of broodstock, etc. The technical difficulty is relatively high, and the above-mentioned technologies are systematically solved The detailed problems can realize the self-propagation of red crayfish in paddy fields, reduce the cost of red crayfish in paddy fields, promote the promotion of red crayfish farming technology, improve the economic benefits of comprehensive rice field breeding, and promote my country's agricultural efficiency and farmers' income.
