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
The present invention relates to a kind of material thrown in pond through probiotics fermention process, and the material after fermentation is utilized by river crab and benthon, the method for breeding river crab that water plant breeds can be promoted again simultaneously, especially the natural bait by the raw material of cheapness and discarded object being converted into high-quality carries out a method for culture of Chinese mitten crab, belongs to cultural technique field.
Background technology
Improve culture of Chinese mitten crab output to have great importance to the income increasing crab agriculture, and the measure of common increase yield is:
1, the breeding density of river crab is improved, the breeding density of unit are is made to be increased to 2000/mu from 500 ~ 1000/mu, the method can improve cultured output, but seedlings of milieu crab cost doubles above, and the commodity crab average size formed under high-density breeding condition is less than normal, selling price is lower, and the effect therefore cultivating synergy is not remarkable.
2, increase the crude protein content in man-made feeds, make the crude protein in feed be increased to more than 40% from 28% ~ 34%.Can accelerate the speed of growth of river crab although increase percent protein, the price of high protein feed is higher, and aquaculture cost significantly increases.
3, increase man-made feeds or the feeding volume of small fish, to increase the nutrition intake amount of river crab, but excessive throwing something and feeding must cause the increase of waste and feeding cost, and easily diseases induced.
4, the stocking size of button crab is increased to 100/kg from 200/kg, to form the commodity crab of more large gauge, the added value of crab is improved.
5, cultivate natural bait or the part feed source of low value discarded object as river crab of throwing something and feeding by fertilising, although the method cost is lower, exists water body and pollute.
Along with the rise in price of feedstuff and the raising of production cost, the benefit adopting the aquaculture model of high investment high production to carry out culture of Chinese mitten crab declines year by year, the difficulty that increases income of raiser is also continuing to increase, and is therefore necessary to find new cultural technique to make up the defect of above-mentioned breeding way.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, a kind of preparation of fermentation materials and the using method in culture of Chinese mitten crab of food organisms bed are provided, the method is by throwing in the material through probiotics fermention to pond, can construct by fermentation materials in pond bottom after rotary tillage is the food organisms bed of main component, fermentation material in this food organisms bed can directly be ingested for river crab, simultaneously can also cultivate water outlet earthworm perching in manor, chironomus larvas, the zoobenthos such as spiral shell and pasture and water and water plant are as the bait of river crab, the intensity of its flood competition can be reduced and improve cultivation survival rate.
The present invention adopts oxygen cylinder and the dual oxygen supply of micro-pore oxygenation machine, the food organisms that dwell can obtain enough oxygen in summer and keep higher multiplication capacity at the end can guaranteeing in food organisms bed, oxygen cylinder is connected with micro-pore oxygenation pipe, summer time opening stage by stage every night, each 1 ~ 10 minute, the dissolved oxygen amount of water body can be made to remain at more than 4mg/L.The food organisms that dwell breed in a large number and can provide extra source of nutrition for the growth of river crab at the end, are conducive to the growth of river crab and the raising of cultured output and benefit.
According to technical scheme provided by the invention, a kind of fermentation materials of the food organisms bed for culture of Chinese mitten crab, formula rate is counted as follows by weight: corncob 1 ~ 35 part, rice straw powder 1 ~ 30 part, zeolite powder 1 ~ 15 part, chicken manure 20 ~ 80 parts, calcium superphosphate 0.1 ~ 1 part, 0.1 ~ 1 part, molasses, humic acid 0.1 ~ 1 part, compound probiotic 0.1 ~ 1 part, 10 ~ 40 parts, water, is fermentation materials by namely obtaining product after above-mentioned material and water mix and blend, the high fermentation of heap, drying.
