Shrimp ponds involve ponds containing freshwater, saltwater, and brackish water. Shrimp is one type of filter animal so that water quality is crucial for the results obtained by farmers. Potential shrimps to be cultivated in ponds are tiger shrimp and vaname shrimp. Both shrimps can tolerate salt levels between 0 to 45 percent.
"UZ-Min" Zeolites are natural minerals made from aluminum silicate groups that are hydrated by alkali metals and alkaline earth. The zeolite mineral is gray to bluish. Clinoptilolite is a type of natural zeolite mineral that has many uses.In aquaculture, Clinoptilolite can be used to help control the quality of the soil at the bottom of a pond. Clinoptilolite forms like crystal and has a variety of colors, namely white, yellow, green, and pale brown based on different qualities.
How does zeolite absorb ammonia nitrogen?
In this article, the researchers discuss the benefits of zeolite for shrimp ponds. they have also published related articles, Zeolite as ammonia adsorber in the pond. Please refer to the article.
Pond water quality is an important thing that must always be considered. According to research, if environmental conditions such as water quality are not following the standards for cultivation it will cause death and ultimately losses in aquaculture. Water quality management is a way to maintain water quality parameters following quality standards for cultivation. These parameters are an indicator to see the quality of water, such as dissolved oxygen (DO), free carbon dioxide (CO2), pH, temperature, brightness, salinity, ammonia, and nitrite.
Zeolite benefit for shrimp pond
Dissolved oxygen should be sufficient. Scientists generally agree that aquatic animals need to be dissolved oxygen at a concentration of 5.0 mg / L or more to be able to live and develop. However, the amount of oxygen needed can also vary depending on how large or complex the animal is and where it lives. The greater the dissolved oxygen value, the better the water quality. The highest difference in dissolved oxygen concentration is found in waters that have high plankton density and vice versa. Most of the waters that have low oxygen levels are caused by a variety of complex factors from natural to man-made factors. The solubility of oxygen in water is influenced by several factors including temperature, the salinity of the waters, movement of water on the surface of the water, the surface area of open waters, atmospheric pressure, and the percentage of oxygen around it.
When the concentration of dissolved oxygen is low, carbon dioxide levels can inhibit the entry of oxygen into pond water. The normal range of carbon dioxide is from 1 to 10 mg / l. If carbon dioxide exceeds 10 mg / l, the water quality is not good.
Too high pH is not good, a pH above 8.5 causes ammonia in the pond to be toxic and raises hydrogen sulfide around it which is also a toxic substance, so don’t overdo it.Temperature or temperature is one indicator of the success of shrimp farming. For this reason, temperature fluctuations must always be watched out for by farmers, because sudden spikes or decreases in temperature can inhibit shrimp growth and can even make shrimp die.
It should be noted by farmers that the optimal temperature for shrimp to grow and develop is in the range of 26 to 30 degrees celsius. The drastic temperature change that can be overcome by shrimp is no more than 2 degrees celsius. If the pond temperature decreases until it reaches 25 degrees Celsius, it can cause the digestibility of food by shrimp will be hampered, this will later influence the growth of shrimp. Vice versa, if there is a surge in temperature to reach 30 degrees Celsius or more, it will trigger stress on shrimp. The stress experienced is due to high-temperature changes that cause shrimp oxygen demand to increase.To avoid stress on shrimp, pond entrepreneurs are required to always check the level of water salinity routinely. In general, the ideal shrimp ponds are shrimp ponds that have a salinity level of around 10-30 ppt.
Zeolite is useful for conditioning pond water quality to conform to shrimp pond standards. Various benefits of zeolite minerals for ponds, namely:
- Zeolite minerals can bind heavy metals in water or pond bottom soils that can threaten the survival of fish/shrimp, such as Pb, Fe, Hg, Sn, Bi, and AS.
- Increase the level of dissolved oxygen in the water
- Because it has a high absorption power, zeolite minerals can reduce gases in the remaining shrimp feed (not eaten), as well as gases originating from the metabolism of other organisms that live at the pond bottom.
- Maintaining the stability of the water temperature, as well as maintaining the degree of acidity (pH) of water in a pond.
- Because zeolites have a high calcium content, shrimp in ponds can be prevented from soft skin diseases.
- Helps the growth of phytoplankton in ponds, so that natural food for shrimp is always maintained.
As water treatment agent in aquaculture,"UZ-MIN" Clinoptilolite Zeolite for Aquaculture has many pores inside , uniform tubular channels and internal surface with large pores which has unique adsorption, screening, exchange of anion and cation and catalytic performance, and can adsorb a large number of toxic substances (such as NH3, NH4 +, CO2, H2S, etc.)
Benefits of UZ-MIN Clinoptilolite Zeolite Granular
- Absorbing ammonia nitrogen, organic matter and heavy metal ions in water
- Good Micronutrient Fertilizer
- Effectively reduce the toxicity of H2S at the pond bottom
- Regulate pH
- Removing ammonia, increasing dissolved oxygen in water, Provide sufficient carbon for phytoplankton to grow, Increase the intensity of photosynthesis in water,
- Optimizing the breeding ecosystem and promote the growth and development of aquatic animals.
Scope Of Application In Aquaculture
- For open type system: Regularly spray zeolite powder into the aquaculture water body, and feed fish, shrimp, sea cucumber, crab, scallop, turtle, eel, etc., both fresh and sea waters .
- For Closed type systems: Used in aquaculture wastewater circulation systems, clinoptilolite can be used as the filter media in the circulation system. (See below Figure)
- For every 1 kg of zeolite applied into the pond, 200ml of oxygen can be brought in and slowly released in the form of microbubbles to prevent deterioration of water quality and fish floatation.
- When the zeolite powder is used as water quality improver, the dosage should be 13 kg per mu of 1m water depth all over the pool.
- Use alone. In general, every mu of water surface every use 6 - 8kg, 7 - 10 days once again, high temperature season or serious disease, to double use.
- Fresh water culture: 15 – 25g zeolite powder per cubic body during normal feeding period, preferably separated from quicklime for better effect; 25 - 35g zeolite powder per cubic body of water before freezing is beneficial to safe wintering and increase survival rate in winter.
