Nowadays, geomembrane has been widely used in various engineering fields. Its good anti-seepage performance and excellent durability can protect groundwater resources from pollution to the maximum extent. In fact, in aquaculture fields such as fish ponds, geomembranes are also increasingly used. Compared with other materials, geomembranes have many advantages.
Advantages of Geomembrane in Fish Farming
Water Retention: Geomembranes prevent water loss due to seepage, maintaining water levels and quality, which is crucial for the health and growth of fish.
Environmental Protection: By preventing seepage, geomembranes protect the surrounding soil and groundwater from contamination by fish waste and feed.
Durability: High-quality geomembranes are resistant to UV rays, chemicals, and punctures, ensuring a long service life with minimal maintenance.
Ease of Installation: Geomembranes are relatively easy to install, making them a cost-effective solution for both small and large-scale fish farms.
Types of Geomembranes for Fish Farming
HDPE (High-Density Polyethylene)
Known for its strength and durability, HDPE geomembranes are ideal for large-scale fish farms.
HDPE geomembranes have the following advantages:
1. Water storage HDPE geomembranes have good water storage performance due to their extremely low permeability coefficient, which prevents water in the fish pond from infiltrating into the soil, effectively monitors the water level, and saves related water retention costs.
2. Water quality stability Using HDPE geomembranes can better maintain the balance of water quality, reduce changes in moisture conditions, and reduce the cost and time of controlling water quality.
3. Oxygen content Using HDPE geomembranes can reduce oxygen loss caused by infiltration into the soil, facilitate monitoring of oxygen content in the water, and reduce the cost of supplementing oxygen in fish ponds.
4. Reduce maintenance costs Using HDPE geomembranes can inhibit the growth of algae in the water and are easy to clean. Since the geomembrane itself contains anti-ultraviolet additives, the geomembrane is not afraid of the sun's radiation and is easy to maintain. The use of geomembranes can provide more convenient monitoring and a safer environment. Since the maintenance cost and time are very low, fishing can be carried out more conveniently and quickly.
5. System stability
Compared with directly digging a pond, the use of HDPE geomembranes can make the slope more stable. It is conducive to eliminating the threats to the fish pond caused by natural conditions such as wind, rain, and waves, maintaining the stability of the system during design, and preventing the loss of farmed crops in the fish pond due to environmental damage. In addition, the use of HDPE geomembranes can make the pond have a steeper slope and a deeper depth, which is equivalent to increasing the output in disguise. The stability of the system, of course, also reduces the maintenance and earthwork costs of the fish pond.
6. Increase production
Because after using HDPE geomembranes, there will be no weeds, sludge, etc. on the bottom of the pond that affect the speed of fishing, so fishing can be carried out more efficiently. The fishing time will be greatly reduced, and the vitality and freshness of fish and shrimp will be greatly enhanced.
7. Disease Hazards
After using HDPE geomembrane, the environmental adaptability of bacteria in the fish pond will be greatly reduced, thus maintaining the healthy growth of fish and shrimp. Since the contact between soil and water is isolated, the chemical substances and pathogens in the soil will not spread to the pond, reducing the possibility of disease transmission. It can be said that the use of HDPE geomembrane reduces the cost of fish farming medicines and the risk of large-scale fish and shrimp deaths due to diseases.
8. Pond Cleaning
After installing HDPE geomembrane, it will be easier to clean the pond. And it is easier to install a clean drainage system in the pond.
9. Improved breeding cycle
After using HDPE geomembrane, it is easier to clean and catch, saving a lot of cost and time, and can speed up the weekly cleaning of fish ponds, which in turn increases production.
LDPE (Low-Density Polyethylene)
More flexible than HDPE, LDPE geomembranes are suitable for smaller ponds and areas requiring more flexibility.
LDPE geomembranes have the following advantages for fish farming:
Excellent Chemical Resistance: LDPE geomembranes are resistant to acids, alkalis, and salts, making them suitable for fish farming ponds where chemicals are used for water treatment and disinfection. This ensures the durability of the membranes and their ability to maintain a stable environment for fish.
Good Flexibility: LDPE geomembranes have good flexibility, which allows them to conform to uneven ground surfaces and adapt to changes in ground conditions. This flexibility ensures a reliable pond lining solution that can withstand the shifting ground conditions often found in fish farming environments.
Low Permeability: LDPE geomembranes exhibit extremely low permeability rates, effectively preventing the leakage of water from ponds. This is crucial in fish farming to maintain optimal water levels and ensure a stable environment for fish growth.
Smooth Surface: LDPE geomembranes have a smooth surface that reduces the risk of fish injuries and entanglement. This contributes to the overall health and welfare of fish in fish farming ponds.
UV Resistance: LDPE geomembranes are treated with UV inhibitors to protect them from the harmful effects of sunlight. This ensures their durability and longevity, even in outdoor fish farming applications.
Cost-Effective: LDPE geomembranes offer a cost-effective solution for fish farming ponds. Their durability and long service life contribute to their overall cost-efficiency, making them a practical choice for fish farmers.
In summary, LDPE geomembranes provide excellent chemical resistance, good flexibility, low permeability, smooth surface, UV resistance, and cost-effectiveness for fish farming applications. These advantages ensure a reliable pond lining solution that can maintain a stable and healthy environment for fish growth.
