Preparation method of fermentation materials in bait biological bed for mainly breeding procambarus clarkia and cooperatively breeding Chinese softshell turtle and use method of fermentation materials

Abstract

The invention relates to a preparation method of fermentation materials in a bait biological bed for mainly breeding the procambarus clarkia and cooperatively the breeding Chinese softshell turtle and a use method of the fermentation materials, belonging to the technical field of cultivation. The method comprises the steps of feeding probiotics-fermented batch mixture, carrying out rotary tillage, and building a bait biological bed which takes the fermentation materials as the main component at the bottom of the pool, wherein the fermentation materials not only can be directly fed to the procambarus clarkia, but also can cultivate the benthonic food animals such as the tubificidae, the chironomidae larvae, the spiral shell and the shellfish to be taken as the high-quality bait of the procambarus clarkia and the Chinese softshell turtle, so that the survival rate of the cultivated animals can be improved due to the abundant natural bait. The bait biological bed is aerated by an oxygen bottle and a microporous aerator in summer, so that the cultivation efficiency of the benthonic food animals can be improved, and the quick growth of aquatic plant can be promoted, and the formed aquatic plant community can be used for inhabiting the procambarus clarkia and preventing the procambarus clarkia from being attached by the predator. The cooperatively-bred Chinese softshell turtle can prey on the weak procambarus clarkia, so that the disease dispersion can be stopped.

Description

technical field [0001] The present invention relates to a kind of breeding of shrimp and soft-shelled turtles which is put in the pond and fermented by probiotics, and the fermented material can be used by Procambarus clarkii, Chinese soft-shelled turtle and benthic organisms, and can also promote the proliferation of aquatic plants. The method, especially a method for cultivating Procambarus clarkii and nesting soft-shelled soft-shelled turtles by converting cheap raw materials and wastes into high-quality natural bait, belongs to the field of breeding technology. Background technique [0002] How to improve the efficiency of Procambarus clarkii farming is a common concern of shrimp farmers, and common measures to increase production and efficiency are: [0003] 1. Increasing the stocking density of Procambarus clarkii is a common technical measure to increase production and benefits, but increasing the stocking density of shrimp fry will greatly increase the cost of farmin...

AI Technical Summary

Problems solved by technology

Although high-protein feed can accelerate the growth rate of Procambarus clarkii, the price of high-protein feed is relatively high, and the cost of breeding has increased greatly;

[0005] 3. Increase the feeding amount of artificial feed or small miscellaneous fish to increase the nutrient intake of Procambarus clarkii, but excessive feeding will inevitably lead to waste of feed, increase of feeding cost and water pollution, and easily cause diseases;

[0006] 4. Adopting the cultivation method of wheel-catching and releasing can improve the production and benefit of cultivation, but for the cultivation of Procambarus clarkii with insufficient seed sources, it is difficult to popularize and apply this method on a large scale;

[0007] 5. Planting a large number of aquatic plants can improve the breeding ecology and provide plant-based bait. However, aquatic plants are one of the main foods for Procambarus clarkii. When the food intake is greater than the growth of aquatic plants, the aquatic plants in the pond will gradually decrease. Both the stability and the survival rate of breeding will decrease accordingly;

[0008] 6. Crab breeding in Procambarus clarkii culture ponds can improve the breeding efficiency, but the two have the same feeding habits, and there is food competition, especially when there is insufficient bait or competition for habitat territory, they are prone to mutual killing;

[0009] 7. Cultivate natural bait by fertilization or feed low-value waste as part of the bait source for Procambarus clarkii. Although this method reduces the cost of breeding, it will pollute the water body

[0010] The extra income can be increased by nesting soft-shelled soft-shelled turtles in Procambarus clarkii culture ponds, but there is also competition between soft-shelled soft-shelled turtles and Procambarus clarkii for food and habitats, and some shrimp fry and soft-shell shrimps are easy to become soft-shelled soft-shelled soft-shelled turtles. Therefore, the guarantee of bait and the setting of concealed objects are the key points to improve the survival rate and breeding efficiency of Procambarus clarkii
