Роль геомембраны в аквакультуре

one:Core features: seepage and leakage prevention

This is the most basic function of geomembranes. Natural ponds and earthen pools have pores in their bottoms and walls, leading to water leakage and loss, as well as the loss of nutrients and feed residue. Laying a geomembrane creates a seamless impermeable barrier, effectively reducing water leakage by more than 95%, lowering the frequency and cost of water replenishment, and making it particularly suitable for aquaculture in water-scarce areas or in easily permeable sites such as saline-alkali land or sandy soil.

Second: Improves water quality and facilitates pollution control.

This makes it easy to clean up through the sewage outlet, reducing the accumulation of harmful substances (such as ammonia nitrogen and nitrite) in the bottom sediment and lowering the risk of eutrophication and disease outbreaks in the water body.

Third: Increase breeding density to increase yield.

Geomembranes isolate water from soil, making water quality easier to control and creating a more stable aquaculture environment, which can increase stocking density per unit area. For example, in fish, shrimp, crab, and frog farming, stable water quality can reduce stress and mortality, thereby increasing overall yield.

Fourth: Reduce pond cleaning costs and shorten the aquaculture cycle.

Traditional earthen pond cleaning requires repeated tilling, sun-drying, and disinfection, a tedious and time-consuming process.

five:Adaptable to various farming models

Geomembranes can be used in various modes of aquaculture, such as pond aquaculture, factory farming, rice-fish integrated farming, and elevated pond aquaculture. For example, in elevated pond shrimp farming, the geomembrane seepage prevention and slope design can achieve efficient sewage discharge; in rice-crab farming, it can prevent water leakage and escape caused by crabs burrowing.

Six: Extend the lifespan of the pond

Geomembranes have the properties of acid and alkali resistance, corrosion resistance, and aging resistance (especially HDPE geomembranes). They can resist the erosion of chemicals in aquaculture water and soil, prevent pond wall collapse and pond bottom subsidence, extend the service life of ponds, and reduce the investment in repeated construction.
