Shrimp pond is an important environment for shrimp farming, and good substrate is the key to ensure the healthy growth of shrimp. However, with the passage of time, a large amount of organic matter, ammonia nitrogen, nitrite and other harmful substances will accumulate at the bottom of the shrimp pond, which will affect the growth and health of the shrimp. Therefore, it is particularly important to change the bottom.
1. Qingtang
The first step in the bottom change is to clear the pond. In winter or spring, drain the water from the shrimp pond to remove silt and debris from the bottom. This helps to reduce the accumulation of organic matter and harmful substances and improves bottom permeability. When clearing the pond, you can use an excavator or manual dredging to remove the silt and debris from the bottom. At the same time, a layer of limestone or zeolite and other substances can be laid at the bottom to adsorb pollutants and harmful substances at the bottom.
2. Use of biological agents
Biological agents are a kind of beneficial microbial flora, such as EM bacteria pioneer, which is a composite flora composed of a variety of beneficial microorganisms, which can decompose organic matter and harmful substances at the bottom, improve the stability of the bottom environment, and improve the disease resistance and growth rate of shrimp.
3. Use a reprimer
A bottomer is a type of agent that is specially used to improve the bottom environment. The commonly used bottom modifiers are: double reform pioneer, oxidation + biological dual action to efficiently decompose the organic matter at the bottom of the pond, purify water quality, improve bottom permeability, and promote the growth and health of shrimp.
4. Change the water regularly
By changing the water, the accumulation of organic matter and harmful substances on the bottom can be reduced, the water quality can be improved, and the growth and health of shrimp can be promoted. When changing the water, it is necessary to pay attention to the quality and quality of the water source to avoid introducing new sources of pollution. At the same time, it is necessary to reasonably change the water according to the growth stage and needs of the shrimp to maintain the stability of water quality.
Fifth, reasonable feeding
Overfeeding can lead to the accumulation of organic matter and harmful substances at the bottom, affecting the bottom environment. Therefore, it is necessary to feed the shrimp reasonably according to their growth stage and needs to reduce bottom pollution. At the same time, it is necessary to choose high-quality feed brands and avoid the deterioration of water quality caused by the use of inferior feed.
6. Strengthen management
It is necessary to regularly check the water quality and bottom environment of the shrimp pond, find problems in time and deal with them. At the same time, it is necessary to strengthen the maintenance and management of equipment to ensure the normal operation of equipment and the stability of water quality. In the process of management, it is necessary to maintain the environmental hygiene and safety of the shrimp pond to avoid pollution and disease.
