Why should pond bottom be treated?
During the shrimp farming process, shrimp waste will mix into the water environment and accumulate at the bottom of the pond. If not treated promptly and properly, it will directly affect the health of the shrimp as well as crop productivity. First of all, farmers need to know the common problems at the bottom of shrimp ponds:
The bottom of the shrimp pond is muddy.
In aquaculture, aeration is a common method to create circular motion in the water, creating the best air for the shrimp farming environment. However, there is one thing that farmers need to note: if aeration is excessive, the bottom and the pond bank area will be eroded. In addition, shrimp waste is also continuously discharged in the form of a mixture of gas, liquid, semi-solid and solid. Some of these wastes will be removed, but some will settle to the bottom of the pond and become pond bottom mud.
The formation of pond bottom sludge will also depend on the design and type of pond, farming system, pond management regime and input materials (fertilizer, feed, treatment chemicals). Sludge appearing at the bottom of shrimp ponds has higher than normal levels of organic matter, total nitrogen, COD, BOD and phosphorus, etc.
Harmful effects of sludge accumulation at pond bottom
The more sludge at the bottom of the pond, the more it will reduce the oxygen at the bottom of the pond, leading to a lack of oxygen in the shrimp. This also makes the shrimp stressed and more susceptible to disease. In addition, when a lot of sludge accumulates at the bottom of the pond, it not only causes a lack of oxygen to decompose sediments, but it also creates anaerobic conditions and forms toxic gases that reduce water quality.
In addition to affecting the quality of shrimp, the sludge from the bottom of the pond when discharged into the outside environment contains too much toxic gas, which will also affect the water quality, natural organisms and the environment of the surrounding areas. This untreated sludge has been released into the outside environment, carrying many pathogens that pose a risk of re-pollution to the shrimp pond and the environment around this area.
Toxic gas at the bottom of shrimp ponds
As mentioned above, the formation of sludge at the bottom of the pond and not thoroughly treated will lead to the formation of toxic gases. This not only affects the water quality but also affects the surrounding areas. So what are the toxic gases that often appear at the bottom of shrimp ponds?
- Toxic gas H2S or Hydrogen Sulfide, this is one of the most common toxic gases that often appears in shrimp pond environments. It is the cause that directly affects the respiratory health of aquatic products and significantly reduces quality. Even if the concentration of H2S is too high, it will lead to mass shrimp deaths.
- Toxic gas NO2 is Nitrite, which is also one of the toxic gases that often appears in shrimp farming environment. This toxic gas comes from shrimp and fish that decomposed in the previous season but people did not clean the pond bottom properly.
- Toxic gas NH3 is also a toxic gas that causes mass deaths of shrimp and fish because it affects the metabolism of shrimp and fish with the outside environment.
Effective pond bottom treatment with Microbe-Lift AQUA SA pond bottom treatment probiotics
Introducing the Microbe-Lift AQUA SA pond bottom treatment probiotic product
In addition to treating the pond bottom by drying the pond, fertilizing or spreading lime, do not forget to use Microbe-Lift AQUA SA probiotics to treat the pond bottom . This probiotic product contains strains of microorganisms with strong activity such as: Bacillus amyloliquefaciens, Bacillus megaterium, Bacillus licheniformis, Bacillus subtilis, Humate, Humic,…
The ingredients in this bottom treatment probiotic help increase the decomposition process of the bottom sludge layer, effectively reduce toxic gases and speed up the decomposition of the surface of the hard scum layer and organic substances that are difficult to decompose.
To use this product, farmers also need to pay attention based on the time and actual condition of the shrimp pond. For reference, the basic instructions for using the Microbe-Lift AQUA SA probiotic product are as follows:
- 100ml of probiotic product to treat the pond bottom + 20 liters to 50 liters of pond water + 3 liters of clean molasses, then stir well and continuously aerate for 24 hours to treat 1000 cubic meters of water.
- The level of product usage after releasing shrimp also depends on the number of days, specifically:
- From day 1-30: You should use the product 1 to 2 times a week.
- From day 30-60: Increase dosage to 2 to 3 times a week.
- From day 60 onwards: Increase to 3 to 4 times a week.
