Microecological preparations, traditional Chinese medicine in South America white
Application of prawn seed cultivation
Microecological agents through the ecological balance theory, biological barrier theory, the theory of biological oxygen capture, the three-flow cycle theory, played a "disease-assisted treatment," "disease prevention," and "disease-free health care," an important role. Traditional Chinese medicine is not easy to produce drug resistance and toxic and side effects, long-lasting efficacy, no residue, and environmental protection; in combination with the use of the two, it has achieved good results in the cultivation of Penaeus vannamei seedlings.
First, materials and methods
1. Material
1, 1 micro-ecological agents: "Miaochi water transfer treasure", "Yi Shui Su", "live bacteria purification agent" produced by the Institute of Botanical Science and Technology of Zhangzhou Wang.
1,2 Traditional Chinese Medicine Preparations: The pure Chinese medicine preparation produced by the Shengzhou Wangsheng Institute of Material Technology—Xin Duwang.
1, 3 Others: “Compound Coated High Stable Vitamin Câ€, Compound Vitamin B, and Tianjin Bleaching Powder produced by Shengzhou Wang’s Material Technology Institute.
1, 4 broodstock: Zhanjiang local cultured South American white second-generation broodstock.
1ã€5 Venue: Tangshan Minnan Shrimp Farm, Haixing County Changsheng Nursery Farm, Hebei Province.
1,6 aquaculture water: seawater in natural sea area.
1, 7 bait: acquisition of local silkworms in Tangshan, shrimp shrimp, algae powder, native rotifers in Haixing County, Artemia bugs.
2, method
2,1 preparation.
The seedling cement pool is soaked with 100PPM bleach for 2 days, and then washed again with 20PPM potassium permanganate, so that the tracheal gasstone is soaked together.
Broodstock water: Use 3 PPM of water purification agent 24 hours ahead of time in the warm-up pond.
Fabric water: 20 days ago, 50 PPM bleach was used to disinfect the water in the sedimentation tank. After no residual chlorine was detected, Yishui 1PPM was applied. After every 15 days, it was supplemented once.
2,2 broodstock and larvae
From February to March of 2007, Tangshan Nursery had successively brought 10,000 pairs of broodstock to Zhanjiang. On April 5, 2007, Haixin County, Changsheng Nursery Farm, Butangshan, South Fujian Province, had 10 million larvae.
2,3 management situation
The broodstock feeds once a day in the morning and evening, and is fed at 5% of the body weight of the broodstock. The amount of bait is adjusted according to the actual situation and the water is changed once a day. After making water changes, make up the "Miaochi Water Transfer Po". Disinfect water with 20PPM formaldehyde. After 24 hours, use “Miaochi Water Diversion†10PPM, cloth young 200,000/m3. Afterwards, use the “Miaochi Water Transfer Pod†5PPM, and the composite coated high-stability VC1 PPM. Composite VB1PPM in the afternoon. Three days after the prawns were changed, the “Drug King†was added 4% of the feed.
Use of 2 and 4 drugs
In the experiment, no other disinfectants and antibiotics were used except for bleaching water for nursery.
Second, results and analysis
1, the result
After four months of breeding, the broodstock has a daily mortality rate of 1/10000. Its body color gradually turns into a clear and transparent color, its body shines, its fecundity is increased by 5% over the previous years, and the hatching rate of larvae is increased by 6%. The success rate of seedless seedlings reached 80%. Haixing County prosperous nursery site cloth 10 million larvae, after 30 days of breeding, selling 9 million prawn, specifications for 50,000 / 500g. From juveniles to baby shrimps, they never fell to the pool.
2. Analysis
2, 1 application of complex strains of "Miaochi water transfer treasure", "Yi Shui Su", "seedling purification agent."
First, it has the connotation of supplementing or enriching the microbial community and maintaining or adjusting the microecological balance. Second, the beneficial substances and secretions produced during the growth of the strains become the substrates and raw materials for their mutual growth or mutual growth. Through this symbiotic and proliferative relationship between them, a stable and beneficial micro-ecological system is formed to inhibit harmful bacteria. Reproduction. At the same time, bacterial secretions can enhance the body's immune system and increase resistance to disease. Third, the three-dimensional transfer of complex bacteria, to maintain the ecological balance of the breeding environment.
2, 2 continuous use of probiotics
Broilers, larvae and juveniles are continuously used as microecological preparations, and beneficial bacteria are predominantly formed to form dominant populations, which reduce or hinder the growth and reproduction of pathogenic bacteria and form a benign cycle, thus solving the problem of disease prevention from the root.
2, 3 application of traditional Chinese medicine preparations
The pure Chinese medicine preparation—Drug Toxin King—is made by a special process—extractable processing. It is easy to dissolve and absorb. It has long-lasting effect and no toxic or side effects.
2,4 test results show
Microecological preparations and traditional Chinese medicines are used in combination to maintain the healthy, effective and sustainable development of the aquaculture industry and are worthy of promotion and application.
