Products Description

For tilapia farming, the use of geomembrane to construct ponds is an advanced model that maximizes its advantages and minimizes its disadvantages. Although it has a high initial investment, it provides ideal conditions for achieving high-density, high-yield, and uniform-sized intensive farming by effectively preventing seepage, facilitating pollution cleaning, and, in particular, fundamentally controlling the over-breeding of tilapia.

Main Advantages

1. Excellent Leakage Prevention:

This is the most core advantage. HDPE geomembranes have an extremely low permeability coefficient, effectively preventing pond water from seeping into the ground, significantly reducing water waste.In areas with high groundwater levels, they also prevent groundwater from seeping into the pond, facilitating precise control of pond water salinity and fertility.

2. Easier Water Quality Management:

Isolating Bottom Sediment: The smooth membrane surface completely isolates pond water from the soil, preventing harmful substances and pathogens in the soil from entering the water body, thus reducing bottom sediment contamination at the source.
Easy Cleaning: After fishing, pollutants such as fish feces and leftover bait on the pond bottom do not seep into the soil and can be directly cleaned with a high-pressure water jet. This significantly reduces the labor and cost of pond cleaning and shortens pond idle time.
Maintaining Fertilizer: After fertilization, fertilizer does not leach into the soil, allowing it to be more efficiently utilized by phytoplankton, improving the cultivation efficiency of bait organisms.

3. Controlling Tilapia Overbreeding :

Tilapia have a notable characteristic: early sexual maturity and strong reproductive capacity. They reproduce naturally in ordinary earthen ponds, resulting in an overabundance of juveniles (commonly known as "successor ponds").

These juveniles compete with commercial fish for oxygen and feed, resulting in uneven size, slow growth, and a high feed conversion rate.

Geomembrane ponds lack the muddy nests where broodstock lay their eggs and hatch, effectively suppressing their natural reproduction. This allows farmers to precisely control stocking density and release size by stocking a single-size fry, achieving all-male or monosex aquaculture, thereby increasing production and profitability.

4. Increasing Dissolved Oxygen:

Light-colored geomembrane ponds (such as white or light blue) reflect more sunlight, increasing light throughout the water column and supporting phytoplankton photosynthesis, thereby increasing dissolved oxygen levels.
