Problems solved by technology

The traditional way of raising seedlings is carried out in a closed seedling cultivation workshop by heating up and feeding commercial compound feed throughout the process. First, the nutrition of commercial compound feed is not as comprehensive and stable as that of fresh biological bait. In addition, commercial compound feed also has mildew and poor palatability. The disadvantages and risks of adulteration with manufacturers, the above problems will lead to the growth and metamorphosis of shrimp seedlings being hindered during the cultivation process, slow growth, polluting water quality, breeding pathogens, etc.
Second, in order to solve the above

Embodiment 1

[0057] The high-health ecological seedling raising method of Litopenaeus vannamei based on biological bait and water quality biological regulation of the present invention comprises the following steps:

[0058] (1) Work before raising seedlings:

[0059] (1-1) Water treatment: select the high tide level and good water quality period to pump seawater into the dark sedimentation pond for 24 hours, then pump it to 1.2 meters thick and 100 mesh fine sand for sand filtration, then enter the dark sedimentation pond for 14 hours, and then pass Fully automatic water treatment system (fine sand filter-protein separation-ozone disinfection-ultraviolet sterilization) purification, filtered through 2 layers of cotton filter bags (5μm pore size) and then put into the nursery pond of the workshop, then weighed 20ppm quicklime powder dissolved in water and used 200 mesh After the sieve silk bag is scrubbed and washed, the water is evenly sprinkled to fully precipitate the suspended matter, ...

Abstract

The invention discloses a litopenaeus vannamei ecological breeding method based on live food and water quality bio-regulation. The method includes following steps: (1), treating water before breeding,and performing live food culture; (2), arranging larvae; (3), breeding, regulating water quality, and preventing and controlling pest and disease; (4), marking thickness, desalting, and transferring.An ecological breeding technique of chlamydomonas plus artemia plus probiotics plus compound Chinese herbal medicine is provided, and natural protein, trace elements and minerals are provided for theshrimp larvae, so that the shrimp larvae have strong physique and resistivity, and ecological shrimp larvae bred by the method are big in size, orderly in specification, quick in growth and high in survival rate. The breeding method is advanced in concept, scientific, reasonable, easy in implementation and suitable for large-scale application in high-health breeding of litopenaeus vannamei and has good social benefit and economic benefit.

Description

technical field [0001] The invention relates to the field of aquaculture, and more specifically relates to an ecological seedling raising method for Litopenaeus vannamei based on biological bait and biological control of water quality. Background technique [0002] In recent years, my country's shrimp farming industry has developed rapidly. China's shrimp farming area and output account for about 1 / 3 of the world, ranking first in the world. Litopenaeus vannamei is the largest shrimp farming species in China; The annual demand is about 1,200-1,300 billion tails, while the demand for shrimp fry of Litopenaeus vannamei is about 950-1,000 billion tails. Since 1992, the outbreak of various viral diseases and bacterial diseases has brought a serious blow to the development of the world's shrimp industry. [0003] The meat of Litopenaeus vannamei is delicious, and the processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18-32°C. It also has a ...
