First, the desalination of the shrimp seedlings is diluted and marked, and the crude time is appropriate for 15 to 20 days. The salinity and pH values ​​are consistent with the aquaculture water use. The larvae are cultivated to a strong physique with specifications of 1.2 to 2 cm, which can greatly increase the survival rate of the culture.
2. Seedlings were stocked before stocking to ensure the survival rate of seedlings. The stocking time should be better when the water temperature is stable at 20°C. Generally does not affect the output and ensure the market specifications, stocking density of about 30,000 per mu is better; pond conditions are superior, can be increased to 40,000 to 50,000 per mu.
Third, feed feeding and aquaculture should use as much as possible the use of nutritious and comprehensive feed for white shrimp. The daily feeding amount is calculated as a percentage of the body weight. The daily dose of 3 gram or less is 7% to 9% of the body weight, and the daily weight of 3 to 6 grams is 5% to 7% of the body weight. The body weight is 6 white. Prawn freshwater aquaculture feed for the above day is 3% to 5% of body weight. With
The body was eaten within 1.5 hours after feeding.
IV. Water Quality Control During the breeding process, change the water frequently and use quicklime to adjust the pH to above 8.0. With photosynthetic bacteria and zeolite powder Quanchiposa to improve the substrate, in order to create a good living environment.
V. Disease Prevention To reduce the occurrence of shrimp diseases, the water body must be sterilized frequently. Disinfect the body of water with dibromohydantoin solution before stocking. After 5 days, add 0.25 kg of solitary bacteria, 0.2 kg of Bacillus subtilis and 5 kg of photosynthetic bacteria to cultivate water. In the mid-aquaculture period, the Chinese herbal medicine, multivitamins, and polysaccharides that protect the liver, protect the liver, and fight viruses should be added irregularly to the feed.
