Why aquaculture should use geomembranes

Fisheries and aquaculture production around the world.

With the rapid development of the aquaculture industry, problems in the industry have become more and more prominent, and the quality and safety of aquatic products, ecological and environmental safety, and biosecurity are facing great challenges.

Why do these problems exist in aquaculture?

The first thing to consider in aquaculture is the construction of aquaculture ponds.

It has to be mentioned is the traditional way of farming, such as direct excavation of ponds, concrete construction of fish ponds, shrimp ponds, so what are the problems that will occur in the construction of traditional aquaculture ponds?

1, traditional ponds directly excavated, drainage is easy to muddy water, seepage, dam collapse.

2, fish ponds dug and poured concrete, seepage slows down, but the cost is high, not conducive to the high cost of pre-investment in farmers.

3, fish ponds use ordinary agricultural film for seepage control, the use of short life, easy to damage, need long-term maintenance, so the cost is also higher.

The traditional fish pond model is not only poor in waterproofing, but the harmful substances in the soil pose a threat to fish or shrimp, such as the chemicals in the leachate will kill fish and shrimp. Although direct excavation of fish ponds is currently less costly in terms of investment, it is not conducive to long-term farming and is more costly in the long run.

What other new construction models are available to improve the problem of aquaculture ponds?

Through comparison, it is found that the use of HDPE geomembrane as the seepage control treatment of aquaculture ponds, with anti-aging, durable, not easy to puncture, and the cost is lower than concrete, suitable for early investment in fishpond aquaculture, the service life of up to 50 years.

What are the specific advantages of using HDPE geomembrane for aquaculture ponds?

1, excellent seepage control performance

HDPE geomembrane has excellent seepage control performance and good water storage performance, which can prevent the water in the fish pond from seeping into the soil, control the water level and save the cost of water conservation. It can also prevent underground harmful substances from seeping back into the fish pond, improve the survival rate of fish and avoid economic losses caused by underground toxic substances pollution.2. Maintaining stable water quality

The use of HDPE geomembrane can better maintain the stability of water quality, reduce the changes in water conditions and reduce the cost of water quality control.

3. Maintain oxygen content

HDPE geomembrane can reduce the loss of oxygen caused by infiltration into the soil, which helps to monitor the oxygen content of the water body and reduce the cost of replenishment of oxygen in fish ponds.4. Accelerate the speed of fishing

HDPE geomembrane can inhibit the growth of algae in the water and is easy to clean. As the geomembrane itself contains anti-ultraviolet additives, the geomembrane is not afraid of sunlight and is easy to maintain. The use of geomembranes provides easier monitoring and a safer environment. As the cost and time of maintenance is very low, it can be captured more easily and quickly, thus saving time cost.

5. Keeping the system stable

Compared with the traditional direct excavation of ponds, using HDPE geomembrane for berms will be more stable, which can reduce the threat of natural conditions such as wind and rain on fish ponds, and maintain the stability of the system during the design to prevent the loss of aquaculture crops due to environmental damage. In addition, the use of HDPE geomembranes allows for steeper slopes and deeper depths in the ponds, which equates to a disguised increase in production. The stability of the system certainly reduces the maintenance and earthwork costs of the pond. 6. Disease prevention

HDPE geomembrane has excellent chemical resistance. The chemicals in the leachate do not pose a threat to the HDPE liner. Therefore, the geomembrane isolates harmful substances and prevents them from spreading.

With the use of HDPE geomembranes, the environmental adaptation of bacteria in fish ponds is reduced, thus maintaining healthy growth of fish and shrimp. Due to the isolation of soil-water contact, chemicals and bacteria in the soil do not spread into the pond, reducing the possibility of disease transmission. It can be said that the use of geomembranes reduces the cost of medication for fish farming and the risk of mass mortality of fish and shrimp due to disease.

7. Increase production

After using HDPE geomembrane, there will be no weeds, sludge and other things on the bottom of the pond that affect salvage, so you can salvage more, reduce salvage time, and enhance the vitality and freshness of the fish and shrimp.

8. Convenient to clean the pond

If HDPE geomembrane is used in fish and shrimp ponds, pond cleaning will be easier, and it is also easier to install a clean drainage system in the pond, reducing the daily maintenance costs.

9. Improvement of breeding cycle

After using HDPE geomembrane, it is easier to clean and catch fish, saving a lot of cost and time, speeding up the weekly cleaning of fish ponds, which in turn improves the production.

10. Long service life

The service life of HDPE geomembrane is up to 50 years.

As HDPE geomembrane is made of high quality polyethylene virgin resin, the main components are 97.5% polyethylene, 2.5% carbon black, anti-aging agents, antioxidants, UV absorbers, stabilizers and other additives, carbon black can improve UV-resistant properties, so HDPE geomembrane is not afraid of sunlight.
