Preparation of fermented material in bait bio-bed for breeding of procambarus clarkii seedlings and application method thereof

Abstract

The invention relates to preparation of a fermented material in a bait bio-bed for breeding of procambarus clarkii seedlings 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 seedling growing pond, and a bait bio-bed with the fermented material as the main component is constructed at the bottom of the seedling growing pond after rotary tillage. The fermented material in the bait bio-bed can directly be eaten by procambarus clarkii seedlings, and bred animals and plants such as Tubificidae, chironomidae larvae, spiral shell, waterweed and the like are high-quality baits for shrimp seedlings. Thus, food competition intensity can be reduced, and survival rate of the seedlings can be raised. 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 procambarus clarkii, and it is conducive to raise seedling growing output and benefit of procambarus clarkii procambarus clarkii. In addition, the bait bio-bed is helpful for formation of waterweed communities, seedling growing ecology can be stabilized and seedling growing risk can be reduced.

Description

technical field [0001] The invention relates to a seedling of Procambarus clarkii which can be used by procambarus clarkii and bottom-dwelling organisms after being put into seedling ponds with fermented materials treated by probiotics, and which can also promote the proliferation of aquatic plants A breeding method, especially a method for raising Procambarus clarkii seedlings by converting cheap raw materials and wastes into high-quality natural bait, belongs to the field of breeding technology. Background technique [0002] Procambarus clarkii culture first needs to solve the source of seedlings. At present, the common sources of seedlings are: [0003] 1. From August to October every year, put broodstock shrimps for mating, spawning and hatching. After the larvae hatch, they are fed with artificial feed to cultivate shrimp seedlings; [0004] 2. From April to July every year, the shrimp seedlings are put into the parents to breed; [0005] 3. From October to November e...

Problems solved by technology

At the same time, because the foraging ability of Procambarus clarkii is far lower than that of other shrimps, the utilization rate of artificial pellet feed is obviously low, and the effect of relying on artificial feed for Procambarus clarkii seedlings is not very satisfactory. The stability of seedling yield and seedling benefit is poor, and the cost of seedling remains high, so it is necessary to improve the above seedling methods
