1. As a feed additive for fish, shrimp, and crabs. Zeolite contains various constant and trace elements necessary for the growth and development of fish, shrimp, and crabs. These elements mostly exist in the form of exchangeable ions and soluble salt bases, which are easily absorbed and utilized. At the same time, it also has various catalytic effects of biological enzymes. Therefore, the application of zeolite in fish, shrimp, and crab feed has the effects of promoting metabolism, growth, enhancing disease resistance, improving survival rate, regulating animal body fluids and osmotic pressure, maintaining acid-base balance, purifying water quality, and also has a certain anti mold effect. The amount of zeolite powder used in fish, shrimp, and crab feed is generally between 3% and 5%.

2. As a water quality treatment agent. Zeolite has unique adsorption, screening, cation exchange, and catalytic properties due to its numerous pore sizes, uniform tubular pores, and large surface area pores. It can absorb ammonia nitrogen, organic matter, and heavy metal ions in 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, improve the intensity of photosynthesis in the water, and is also a good trace element fertilizer. For every 1 kilogram of zeolite applied to the fishing pond, 200 milliliters of oxygen can be introduced and slowly released in the form of microbubbles, which can prevent water quality deterioration and prevent fish from floating. When using zeolite powder as a water quality improver, the dosage should be about 13 kilograms per acre at a depth of one meter and sprayed throughout the entire pond.

3. Use materials for building fishing ponds. Zeolite has many pores inside and has strong adsorption capacity. When repairing fishing ponds, people abandon the traditional habit of using yellow sand to lay the bottom of the pond. Instead, they use yellow sand to lay the bottom layer and zeolite with the ability to exchange anions and cations and adsorb harmful substances in the water to be sprinkled on the top layer. This can keep the water color of the fishing pond green or yellow green all year round, promote the rapid and healthy growth of fish, and improve the economic benefits of aquaculture.
