Product Description:
Aquaculture is a production activity of artificial reproduction, cultivation and harvesting of aquatic animals and plants. Generally, it includes the whole process from seedling cultivation to aquatic product cultivation under artificial feeding management. In a broad sense, it also includes the proliferation of aquatic resources.

Key points of Construction:
The anti-seepage geosynthetic membrane is generally used as the base of aquaculture pond to store water. The anti-seepage membrane replaces the previous cement pond, which reduces the cost and makes the construction simple. There are three ways of aquaculture, such as coarse culture, intensive culture and high-density intensive culture. Coarse culture is to put seedlings in small and medium-sized natural waters, and develop aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow water.
Intensive culture is to develop aquatic products by feeding and fertilizing in small water body, such as pond culture, cage culture, fence culture, etc. High density intensive culture adopts the methods of running water, temperature control, oxygenation, feeding high-quality bait, etc. to carry out high-density intensive culture in small water body, so as to obtain high yield, such as running water high-density fish culture and shrimp culture. However, the impermeable membrane is non-toxic and harmless, with long service life, which is the best choice for farmers.
Geotechnical Requirements
The fish pond impervious membrane is made up of 97.5% high density polyethylene and 2.5% carbon black, anti-aging agent, antioxidant, UV absorber, stabilizer and other excipients. It has the features of environmental protection, anti-seepage, leak proof, moisture proof, isolation, root blocking and puncture prevention.
Aquaculture geomembrane can inhibit the growth of algae in water and is easy to clean. Because the geomembrane itself contains anti ultraviolet additives, so the geomembrane is not afraid of the sun, easy to maintain, the use of geomembrane can provide more convenient monitoring and safer environment. Because the maintenance time and cost are very low, it can be fast and convenient for fishing.
