High risk of fish death on dry days? Learn how to properly manage a fish pond
The dry season is coming. The temperature will rise. As a result, the water level in the river ponds will also decrease. In such cases, the risk of death of the fish is quite high. Farmers also have to bear the brunt of the death toll. For this, proper management of the fish pond during the dry season is essential. As a result, farmers will be able to avoid financial losses by reducing the death toll.
Water level:
Fish ponds must have a water level of at least 6 feet. If the water level in the pond is low, the farmers can fill the pond in some other way. Farmers who do not have the opportunity to do so need to catch large fish from the pond and sell them. If the fish are caught in large quantities in phases, the farmers will be spared the sudden loss of fish or drought.
Controlling oxygen in reservoirs:
Due to the high temperatures in the dry season, there is a lack of oxygen in the reservoir. The heat of the pond increases the temperature of the pond. And it affects the dissolved oxygen. To overcome this, farmers need to be able to pump water first and increase their water level.
In addition, water needs to be pumped into the pond by air or water pumps. As a result, the amount of dissolved oxygen in the water will increase and the fish will not die. Also, bring oxygen powder, tablets, or calcium peroxide from nearby aquacaps.
Symptoms of lack of oxygen:
Symptoms of lack of oxygen in the pond are that the fish come to the surface of the pond water and open their mouths to collect oxygen. In addition, these symptoms appear in fish from midnight to early morning. If these symptoms are found in a pond, they should be treated immediately, otherwise the fish could die from lack of oxygen. At this time some of the chemical factors of water and Ph.D. Acid and alkalinity, ammonia, nitrite water block should be tested.
When the water turns blue:
The more water the pond becomes, the more blue the plant becomes. This is done by lowering the water level of the pond. Decreasing the water level in the pond increases the amount of waste cannabis and ammonia nitrite in the mud and creates a toxic environment for fish.
This condition is caused by the exposure of sunlight and heat to the lowering of the water in the light pond. If this type of toxic environment occurs, farmers should be able to apply 20-30 kg per acre of neelite in the pond, in addition to bringing 40 kg of lime per acre of water.
