TREATMENT OF POND-BOTTOM SLUDGE, DIRTY MUD, AND POISON GAS

One of the causes of disease and pollution in shrimp ponds is pond-bottom sludge. However, lining the pond bottom to avoid the impact of this situation is very expensive, and not all farming households can afford to do so. In addition, shrimp often have the habit of digging into the pond bottom to find food. This behavior in an environment that has organic sludge will adversely affect their intestinal tract, causing damage to the farmers’ crops. Therefore, the treatment of shrimp pond bottom sludge is vital, helping to limit pathogens and pond water pollution, thereby helping shrimp be healthy, increase productivity, and achieve high economic efficiency.

Reason of pond-bottom sludge, dirty mud, and poison gas:

• The high amount of leftover dirty bottom mud due to poor pond improvement.
• Excess food, shrimp waste, and shrimp shells settle to the bottom, making the pond bottom more and more sludgy.
• The water source is contaminated with organic matter.
• The pond soil is eroded by the flow of water from the fan running, and the soil on the pond bank is washed away.
• Dead animals of all kinds.
• Excess lime and minerals.

Harm:

Dirty pond bottom will cause pond degradation, water pollution affects the growth of shrimp farming.

• The bottom mud layer is home to harmful bacteria, fungi, and protozoa.
• The decomposition of pond bottom sludge will produce toxic gases such as NH₃, and H₂S, causing poisoning and stress for shrimp.
• Lowers bottom oxygen.
• Create conditions for algae to grow
• Easy to cause diseases for shrimp such as black gills, and worn antennae.. affecting the health of cultured shrimp and reducing crop productivity.

How to treat pond-bottom sludge, dirty mud, and poison gas:

• Thoroughly improve the pond for each new crop.
• Limit the erosion caused by the flow by washing the pond many times, firmly building the pond system, and thoroughly reinforcing the pond bank.
• Strictly manage the feeding, and reduce the amount of excess food.
• Remove the bottom sludge from the pond by changing the water, siphoning, and siphoning the bottom of the pond.
• Use probiotics: Microbiological products: a strain of beneficial bacteria Bacillus capable of decomposing bottom sludge and excess organic matter in water.

  

Proposed Solutions of Thai Nam Viet:

The treatment of excess organic matter and pond-bottom sludge is essential to keep the water environment clean and improve the health and development of aquatic animals. However, when the product is put into the pond, in addition to its effectiveness, it must be environmentally friendly and not adversely affect aquatic animals. Therefore, the use of microbial products is the optimal choice to treat pond-bottom sludge.
