Problems solved by technology

Although increasing the protein content can speed up the growth rate of river crabs, the price of high-protein feed is relatively high, and the cost of breeding will increase significantly
[0005] 3. Increase the feeding amount of artificial feed or small miscellaneous fish to increase the nutrient intake of river crabs, but excessive feeding will definitely cause waste and increase the cost of feeding, and it is easy to cause diseases
[0007] 5. Cultivate natural bait through fertilization or feed low-value waste as part of the bait source for river crabs. Although the cost of this method is low, it will pollute the water body

Abstract

The invention relates to preparation of a bait bio-bed for breeding of river crabs and an application method thereof, and belongs to the field of a cultivation technology. According to the method, a probiotic-fermented batch is poured into a pond, and a bait bio-bed with the fermented material as the main component is constructed at the bottom of the pond after rotary tillage. The fermented material in the bait bio-bed can directly be eaten by river crabs, and cultivated animals and plants such as Tubificidae, chironomidae larvae, spiral shell, waterweed and the like also can be used as the bait of river crabs. Thus, it is conducive to reduce food competition intensity and raise survival rate of river crabs. By dual oxygen supply of an oxygen tank and a micropore aerator in the bait bio-bed in summer, it is conducive to raise culturing efficiency of demersal food organisms. The cultivated natural bait can be used to provide extra nutrition sources for the growth of river crabs, and it is conducive to raise culturing output and benefit of river crabs.

Description

technical field [0001] The present invention relates to a kind of river crab breeding method that puts in the pond the material that has been fermented by probiotics, and makes the fermented material be used by river crabs and benthic organisms, and at the same time can promote the proliferation of aquatic plants. The invention relates to a method for transforming cheap raw materials and waste into high-quality natural bait for cultivating river crabs, belonging to the field of cultivating technology. Background technique [0002] Increasing the production of river crab is of great significance to increasing the income of crab farmers, and common measures to increase production are: [0003] 1. Increase the stocking density of river crabs, so that the stocking density per unit area increases from 500 to 1000 / mu to 2000 / mu. This method can increase the breeding output, but the cost of river crab seedlings is more than doubled, and in high-density breeding The average size of...
