Aquaculture farm is the production activities of breeding, cultivating and harvesting aquatic animals such as fish or shrimp under artificial control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. It can also include the proliferation of aquatic resources in a broad sense. There are extensive, intensive and high-density intensive aquaculture methods. Extensive aquaculture is to put seedlings in medium and small natural waters, and rely entirely on natural bait to grow aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive culture is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish culture, fish culture in cages, and fence culture.
1. Case Study of Geomembrane Pond Liner Indonesia for Aquaculture Farm
Indonesia, set between the Pacific and Indian Oceans, has a tropical climate that supports extensive fisheries. Spanning over 2.7 million square kilometers, these fisheries rank third globally. The country’s seafood is in high demand internationally, leading to increased exports. Recognizing this, the Indonesian government is taking steps to ensure the long-term health of its aquatic resources.Tropical conditions promote diverse marine life, ideal for natural growth and aquaculture.
Our Indonesian clients planned an 80,000 square meter shrimp farm but faced poor harvests and high mortality due to weather and disease. This led them to consider using pond liners for more intensive farming.
Problems and Solutions
Geomembrane Pond liners are perfect for aquaculture due to their cost-effectiveness and anti-seepage properties. They are made of flexible polymers that are lightweight, stretchy, adaptable, resistant to corrosion and cold, and perform well in freezing conditions. Fish ponds lined with this material benefit from its eco-friendly nature, ease of cleaning, and feeding. The geomembrane is precise, preventing air leaks and damage. It withstands temperature extremes, has great chemical stability, and combines stiffness with toughness for superior mechanical strength. Increasing density enhances its barrier capabilities and tensile strength, making it more heat-resistant. It stands up to acid, alkali, and solvent exposure.
Our clients, who have construction experience and are familiar with geomembrane products, requested a 0.75mm thick liner. We’re providing geomembrane products that meet these specifications for their project.
2. 0.75mm Geomembrane Pond Liner for Aquaculture Farm in Indonesia
- HDPE Liner Thickness – 0.75mm
- Total Quantity – 80,000 Square meters
- Each Roll Size – 7m*280m
3. What Are Benifits of Geomembrane Pond Liner for Aquaculture Farm?
And the confirmation of aquaculture farm pond drawings we knew that their main requirements for HDPE geomembrane liner in aquaculture ponds has the following benefits.
3.1 Save cost of storing the water.
HDPE geomembrane liners effectively store water and prevent leaks into the ground. They also stop toxic substances from back-flowing into ponds, boosting fish and shrimp survival rates. These liners resist acid and alkali, combat microbial corrosion, and ensure impermeability.
3.2 Maintain stability of water quality.
Keep the water in stable quality and reduce cost of control the water quality
3.3 Keep oxygen content.
Reduce the oxygen loss because of water leakage into ground; Reduce cost to supplement oxygen in water.
3.4 Quick harvest, save pond exposure time.
HDPE geomembrane liner can inhibit the growth of algae even under sunlight exposure as its UV resistance, it also can achieve quick harvest. The HDPE geomembrane pond liner can also avoid the weed and sludge.
3.5 Keep pond design structure stable.
Geomembrane pond liner can strengthen the pond slope, reduce the risk brought by rains, wind or birds, save building cost of using concrete.
3.6 Lower the risk of disease.
Pond Liner can effectively isolate the different pond and reduced risk of disease in different aquaculture pond areas. HDPE geomembrane liner can deal with the dirt in the pool and has the characteristics of good tensile resistance, impact resistance, tear resistance and high hydrostatic resistance.
3.7 Improve the shrimp farming culture-cycle.
When the soil pond harvest 2 seasons while HDPE pond liner can harvest 1 more season.
3.8 Pond cleaning.
After installing HDPE geomembrane pond lner, it will be easier to clean the pond. And it is easier to install a clean drainage system in the pond.
3.9 Improve the breeding cycle.
As HDPE geomembrane is used, it is easier to clean and fish, which saves a lot of cost and time, can speed up the breeding cycle of fish ponds, and increase production in disguise.
4. How To Install HDPE Geomembrane for Aquaculture Farm Project in Indonesia
4.1 Cleaning preparation
The dyke slope is cleaned, the site is leveled, all sharp corners are removed, the under-slope is backfilled and compacted, and the rich slope is cut and flattened after being qualified by the supervision and acceptance, providing a working surface for laying the HDPE geomembrane liner；
4.2 Splicing
Splicing in the geomembrane liner in order to facilitate the construction and ensure the quality of splicing, the geomembrane liner should be as wide as possible to reduce the amount of splicing on site. Before construction, it should be cut in the unit and spliced according to the width of the HDPE geomembrane pond liner and the length of the site. Form a block that meets the required size, roll it on the steel pipe, and manually transport it to the working surface for laying;
4.3 Laying
Roll paving horizontally along the axis of the channel. After the slope is laid on the slope, it is rolled along the axis of the slope, and the HDPE geomembrane at the bottom of the canal adopts a T-shaped connection;
4.4 Precautions
Geomembrane installation should be carried out in dry and warm weather. In order to facilitate splicing and prevent stress concentration, the HDPE geomembrane pond liner is laid in a wave-shaped relaxation method with a margin of about 1.5%. The slope surface is smooth and consistent, without protrusions and wrinkles. The construction personnel should wear flat-bottomed cloth shoes or soft rubber shoes. Spikes are strictly prohibited to avoid stepping on the geomembrane. If the geomembrane is found damaged during construction, it should be repaired in time.
