The role of zeolite in aquaculture

1. Used as feed additive for fish, shrimp and crab
Zeolite contains a variety of macroelements and trace elements necessary for the growth and development of fish, shrimps, and crabs. These elements mostly exist in the form of exchangeable ions and soluble salt bases, which are easier to absorb and utilize. They also have various catalytic functions for biological enzymes. effect. Therefore, the application of zeolite in fish, shrimp, and crab feed can promote metabolism, promote growth, enhance disease resistance, improve survival rate, regulate animal body fluids and osmotic pressure, maintain acid-base balance, and purify water quality. It also has certain effects. Anti-mildew effect. The dosage of zeolite powder in fish, shrimp and crab feed is generally between 3% and 5%.
2. Use as water quality treatment agent
Zeolite has unique adsorption, screening, exchange of anions and cations, and catalytic properties due to its many internal pore sizes, uniform tubular pores, and pores with large internal surface area. It can absorb ammonia nitrogen, organic matter and heavy metal ions in the water, effectively reduce the toxicity of hydrogen sulfide at the bottom of the pool, adjust the pH value, increase dissolved oxygen in the water, provide sufficient carbon for the growth of phytoplankton, and increase the intensity of photosynthesis in the water. It is also a Plant a good trace element fertilizer. Every kilogram of zeolite applied to a fishing pond can bring in 200 ml of oxygen, which is then slowly released in the form of microbubbles, which can prevent water quality from deteriorating and fish from floating on their heads. When zeolite powder is used as a water quality improver, the dosage should be about 13 kilograms per mu per meter of water depth and sprinkled throughout the entire pond.
3. Used as materials for building fishing ponds
Zeolite has many pores inside and has extremely strong adsorption capacity. When people repair fishing ponds, they abandon the traditional habit of using yellow sand to pave the bottom of the pond. They use yellow sand on the bottom layer and spread it on the upper layer. Zeolite acts as a substance, which can keep the water color of fish ponds green or yellow-green all year round, promote the rapid and healthy growth of fish, and improve the economic benefits of breeding.
