Recommended geomembrane for fishpond aquaculture


Release time:

2025-12-25

In fishpond aquaculture, the effectiveness of seepage prevention directly impacts water quality stability and aquaculture profits, making the selection of a suitable geomembrane crucial. Currently, HDPE geomembrane is the preferred material for fishpond aquaculture due to its acid and alkali resistance, aging resistance, and strong seepage prevention properties, perfectly suited for the long-term immersion and complex water conditions of fishponds.

In fishpond aquaculture, the effectiveness of seepage prevention directly impacts water quality stability and aquaculture profits, making the selection of a suitable geomembrane crucial. Currently, HDPE geomembrane is the preferred material for fishpond aquaculture due to its acid and alkali resistance, aging resistance, and strong seepage prevention properties, perfectly suited for the long-term immersion and complex water conditions of fishponds.

It is recommended to prioritize virgin black HDPE geomembrane. Virgin material avoids the problems of impurities and easy damage associated with recycled materials, while the black color effectively inhibits algae growth, reducing pond cleaning costs. Regarding thickness, 0.5mm-1.0mm is recommended for standard fishponds, while 1.0mm-1.5mm thick geomembrane is suggested for deep-water fishponds or large aquaculture ponds to enhance puncture resistance and prevent damage from fish, shrimp, or sharp objects on the bottom.

For even higher seepage prevention and protection, a two-layer non-woven fabric composite geomembrane can be chosen. The two layers of non-woven fabric effectively protect the middle membrane, improving tensile and puncture resistance, making it suitable for sandy soils or fishponds with complex bottoms.

When purchasing, it is recommended to choose products with national standard certification and prioritize manufacturers that provide welding and installation services to ensure no leakage at the membrane joints. In addition, during construction, it is essential to ensure a level substrate and remove sharp stones to prevent membrane damage and extend its service life. Choosing the right geomembrane for fishponds can significantly reduce water leakage, decrease the frequency of water changes, and help improve aquaculture efficiency.
