Below are scientific references to support the use of HDPE geomembrane in aquaculture farming application:
1. Aquaculture farms in Belize: Robins P. Mclntosh, 2000, reported how using an HDPE liner reduced erosion of pond banks, increased the speed of the turn-around time between crops, sustained water levels, and improved pond efficiency.
2. Agromarina de Panama Farm, Panama: Bray et al., 2001, issued a report describing how the destructive White Spot Syndrome Virus(WSSV) was bringing production to a halt in earthen ponds. The report found that survival rates increased from 9% in earthen ponds to 80% in ponds lined with a 0.75mm HDPE geomembrane.
3. East Java, Indonesia: N. Taw et al., 2002, reported that productivity improved from 3634kgs/ha in an earthen pond to 10094kgs/ha in ponds lined with HDPE geomembrane.
HDPE Pond Liner Advantages in Aquaculture Application
1. Secure water containment
(help keep pond water volume consistent and prevent the intrusion of groundwater borne pollutants from entering aquaculture ponds)
2. Enhanced water quality control
(no additives or chemicals of leaching out and impacting water quality or harming animal life, repeat clean available, resistance to microbiological attack and growth)
3. Minimized pumping costs
4. Dissolved oxygen level control
5. Smooth harvesting surface cleans easier than soil therefore increases the harvest cycle
6. Rapid installation, Low cost installation & maintenance Cost, Easy repair
Comparison between two between two types of pond farming
Earthen (or concrete) Pond Farming | HDPE Liner Lining Pond Farming |
Harmful acid, alkaline in soil and water maintenance | Good water maintenance without soil pollution |
Underground water becomes salty due to seawater seeping | No happening of this case |
Fast plankton growing in the later stage of culturing | Slow plankton growing in the early stage but become stable in the later stage |
Difficult to remove organics which will cause contamination | |
Require treatments after harvest (eg. basking, soil replacement and sterilization etc.) | Can be used after fresh water cleaning only |
Dike is easily destroyed by water wave or crabs
| Difficult to be destroyed because of high tensile strength and excellent elasticity of hdpe liner |
Shrimp gill are easily contaminated by mud | Gill will not be polluted |
Two crops per year | Three or four crops per year |
High cost and long construction period | Cost can be saved 20%-50% |
Rough surface which will cause fish or eel or shrimp to be hurt | Smooth surface which will greatly reduce the risk of hurting aquaculture animals |
