In the rainy season, heavy rain will make prawn & shirmp in stress state , and greatly reduce the disease resistance.
The incidence rate of diseases such as jejunal emptying, gastric emptying, white spot red body and other question will improve bviously.
What are the problems we should pay attention in the rainy season?
1. Water temperature change.
Generally, the temperature of rainwater is lower than that of shrimp pond water, and the temperature difference
between them is even worse in summer.
2.Lack of oxygen in water.
the rainfall leads to the stratification of salty and fresh water, hindering the bottom water and upper water
Oxygen exchange of water, bottom water hypoxia.
3.The water becomes clear
The death of a large number of algae not only directly pollutes shrimp ponds, but also makes them grow moss,
which makes shrimp extremely dangerous.
4.Deterioration of water quality
Increase of chemical oxygen demand (COD), the increase of harmful substances such as ammonia nitrogen and
nitrite in the water body,and the injection of rainwater, resulting in the decrease of pH, and the deterioration of water quality in a short time.
