Problems solved by technology
[0002] It has been found in practice that during the seedling and breeding process of Penaeus vannamei, the survival rate of shrimp seedlings and aquaculture output are often reduced year by year due to problems such as water pollution and bacterial infection, and the economic benefits continue to decline.
In order to solve these problems in the breeding and breeding of Penaeus vannamei, farmers often use disinfectants such as formalin and bleach to disinfect the water body, but it is difficult to be effective

Embodiment Construction
[0013] 1. Experimental materials
[0014] 1. The micro-ecological fungicide for aquaculture water consists of high-concentration Bdellovibrio powder with a concentration of more than 3.3 billion per gram, Bacillus amyloliquefaciens microcapsules with a concentration of more than 2 billion per gram, and soluble starch with an effective content of more than 99%. , wherein the mass ratio of high-concentration Bdellovibrio powder, Bacillus amyloliquefaciens microcapsules, and soluble starch is 4:2:3.
[0015] The preparation method is to uniformly mix the microcapsules of Bacillus amyloliquefaciens and soluble starch at normal temperature, the stirring speed is 30r / min, and the stirring time is 30min, and then add the high-concentration Bdellovibrio original powder at normal temperature. Mix evenly under the hood, the stirring speed is 30r / min, the stirring time is 60min, and the two stirring and mixing processes are all in a closed state.
[0016] 2. The substrate improvement ag...

The invention discloses methods for increasing the live young shrimp quantity of young shrimp breeding and the breeding yield of Penaeus vannamei Boone. The method for increasing the live young shrimp quantity of young shrimp breeding of the Penaeus vannamei Boone comprises the step as follows: an aquatic water micro-ecological fungicide with the dosage of 1.5-2.5 ppm and an aquatic water substrate modifier with the dosage of 0.7-1.2 ppm are splashed to a whole pond each day. The method for increasing the breeding yield of the Penaeus vannamei Boone comprises steps as follows: the Penaeus vannamei Boone is fed with feed once in the morning, at noon and in the afternoon each day; the aquatic water micro-ecological fungicide is not mixed with the feed in the morning; the aquatic water micro-ecological fungicide is mixed with the feed at noon and in the afternoon, and 220-230 g of the aquatic water micro-ecological fungicide is evenly mixed with every 100 kg of the feed. Compared with traditional methods, the methods have the advantages that effects are more significant, application and popularization of the methods are more beneficial to reduction of usage of chemical disinfectants such as formalin, bleaching powder and the like during breeding, and secondary pollution caused by usage of the chemical disinfectants to aquatic water is relieved.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for increasing the number of living seedlings and the breeding output of Penaeus vannamei. Background technique [0002] It has been found in practice that during the seedling and breeding process of Penaeus vannamei, the survival rate of shrimp seedlings and aquaculture output are often reduced year by year due to water pollution, bacterial infection and other problems, and the economic benefits continue to decline. In order to solve these problems in the breeding and breeding of Penaeus vannamei, farmers often use disinfectants such as formalin and bleach to disinfect the water body, but it is difficult to be effective. Contents of the invention [0003] The technical problem to be solved by the present invention is a method for increasing the live seedling quantity of Penaeus vannamei to overcome the deficiencies in the prior art. [0004] In order to solve the p...
