Description
Technical Field
The invention relates to the technical field of marine culture, in particular to a device and a method for hatching shrimp zygotes in running water.
Background
The Litopenaeus vannamei (Litopenaeus vannamei), commonly known as white shrimp or white shrimp, has the advantages of strong adaptability, wide salt tolerance, rapid growth, long breeding period, delicious taste and the like, is introduced into China since 1988, and is in the first place in the current prawn breeding field in China, regardless of the breeding area or total yield. The litopenaeus vannamei belongs to an open seminiferous vesicle type, can be continuously mated for a plurality of times to lay eggs, fertilized eggs belong to sinking eggs, egg pushing is carried out at certain intervals during incubation, namely, an automatic egg pushing device or a special stirring tool is manually adopted to push water in an incubation pool, so that the fertilized eggs float in the water along with the flow of the water, and the phenomena of local hypoxia and long-time accumulation in the incubation process of the fertilized eggs to cause incubation failure and reduction of the incubation rate are prevented. In the industrial Litopenaeus vannamei seedling raising, high-quality nauplii are the premise of improving the survival rate of the raised seedlings and are the key for incubating healthy shrimp seedlings, the nauplii are optimized by light induction, running water cleaning and other methods in the industry, and abnormal nauplii are eliminated, so that the infection and the propagation of harmful vibrios can be effectively prevented, and therefore, pathogens are prevented from being carried to a seedling raising workshop, and the method has important significance for culturing high-quality, healthy, efficient and specific pathogen-free Litopenaeus vannamei seedlings.
