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 problems, a large number of chemical drugs such as disinfectants and antibiotics are used or the water temperature of seedlings is raised above 33°C to increase the metamorphosis survival rate of larvae and shorten the metamorphosis time, resulting in poor quality of seedlings and low disease resistance and survival. In addition, the use of disinfectants and antibiotics destroys the normal flora of the seedling water body, and it is difficult for the probiotic flora to form an advantage. The explosive growth of drug-resistant flora finally makes the total number of pathogenic Vibrio in the seedling water body unable to be obtained. Effective control

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 ...
