Effect of Dissolved Oxygen Sensor in Penaeus vannamei Culture

August and September are the peak seasons for aquaculture production and a critical period for the management of Penaeus vannamei aquaculture. It is necessary to strengthen the management of pond mouths. Through the study and understanding of shrimp farming techniques and methods, can help us to have a good idea when we encounter similar problems in the later stage, solve related problems through reasonable methods, and try to avoid some unnecessary losses.

Effect of Dissolved Oxygen Sensor in Penaeus vannamei Culture

1.Reasonable feeding of bait:
Penaeus vannamei is cultured in warm water, and it is the peak season of feeding and growth at present, so we should seize the opportunity to feed reasonably. Generally, the daily feeding amount accounts for about 2% of the total amount of prawns. The specific feeding amount should be based on the food, weather, and water temperature of the prawns. According to the phototaxis habit of prawns, feed less during the day, accounting for 30-40% of the feeding amount, and more in the evening, accounting for 60-70% of the feeding amount.

2.Adjust water quality in a timely manner:
The water level of the prawn pond should be kept at 1.2-1.5 meters in the high temperature season. The conditional shrimp pond should be added and changed with new water once a week. The amount of water added and changed should be about 10 centimeters. To keep “fat, alive, tender and refreshing”, turn on the aerator for 2 to 3 hours at noon on sunny days to promote convection between the upper and lower layers and avoid oxygen stratification. The dissolved oxygen sensor can monitor the oxygen content in the shrimp pond online in real time, helping you switch the aerator on and off at the right time.

3.Strengthen disease prevention and control:
August and September are the peak seasons for the growth of Penaeus vannamei, and also the peak season for the prevalence of diseases. In addition, Penaeus vannamei lives in water. Once it gets sick, it is very difficult to treat and isolate. Therefore, the prevention and control of shrimp diseases regularly uses microbial preparations, and feeds immune polysaccharides or VC to enhance the immunity of shrimp bodies. The combination of internal administration and external elimination can effectively Prevent the occurrence of shrimp disease.

4.Adhere to pond inspections:
Visit the pond three times a day in the morning, noon and evening. One is to observe the activity of the prawns and find out the cause in time if any abnormalities are found. Check the water quality, look at the color and transparency of the water, find abnormalities, take corresponding measures as soon as possible, and turn on the aerator. Desun uniwill water quality sensor can help you monitor the water quality in the pond in real time. The data that can be monitored include dissolved oxygen, pH, salinity, ammonia nitrogen, turbidity, etc., to help you discover abnormal water quality in the first place and reduce unnecessary risks, etc. .

5.Rotary catch and listing:
After dozens of days of feeding, some of the prawns have reached the market specification, and the method of catching large and small prawns that have reached the market specification is used to catch and market the prawns that have reached the market specification, reducing the density of the pond, increasing the activity space of prawns, and improving the quality of prawns. Farming production and economic benefits.
