Production and use method of fermented material for bait biological bed for macrobrachium prawn seed propagation

Abstract

The invention relates to a preparation method of fermentation materials in a bait biological bed for breeding Japanese macrobrachium superbum offspring seed and a use method of the fermentation materials. The method comprises the steps of feeding probiotics-fermented batch mixture into a seedling pool, 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 in the bait biological bed can be directly fed to the Japanese macrobrachium superbum offspring seed, and the benthonic animals such as the tubificidae, the chironomidae larvae, the spiral shell and the aquatic plant as well as the aquatic plant can be cultivated to be taken as the bait of the Japanese macrobrachium superbum offspring seed in a habitat domain, so that the strength of the food competition can be reduced, the seedling survival rate can be improved, and the growth, the seeding yield and the benefit of the Japanese macrobrachium superbum can be improved. In order to guarantee that the benthic bait organisms in the 'bait biological bed' still has high multiplication capacity even in summer, the bait biological bed is aerated by an oxygen bottle and a microporous aerator, and the oxygen bottle and the microporous aerator are connected with each other and are started by stages at the fixed time at every night.

Description

technical field [0001] The present invention relates to a kind of material that has been fermented and treated by probiotics in a nursery pond, and the fermented batch material can be used by Macrobrachium japonicus and benthic organisms, and at the same time, it can promote the reproduction of macrobrachium japonicus seedlings method, especially a method for raising giant macrobrachium prawns by converting cheap raw materials and waste into high-quality natural bait. Background technique [0002] Improving the production of Macrobrachium japonicus first needs to solve the problem of seed source, and the common sources of seed are: ① Stocking Macrobrachium japonicus broodstock from May to July for mating, spawning and hatching, and cultivating by feeding artificial feed with fertilizer and water Adult shrimp seedlings; ②Breeding shrimp seedlings using industrial seedling breeding technology; ③Stocking shrimp seedlings at the end of the year, and breeding them until sexually ...

AI Technical Summary

Problems solved by technology

With the price increase of feed materials and the increase of production costs, the benefits of the high-input seedling breeding mode of feeding a large amount of artificial feed are declining year by year, and it is increasingly difficult for farmers to increase income. Therefore, it is necessary to find new seedling raising technologies to make up for it. Defects of the above seedling raising methods
