Aquaculture Dam Liners and Fish Tank Liners Australia

Aquaculture Dam Liners and Fish Tank Liners

Leak-Proof, UV-Resistant Liners for Fish Transport, Treatment, and Marine Operations.
Fleximake designs and manufactures custom fish tank liners for Australian aquaculture. They
protect fish and improve efficiency in Australia’s diverse fish farming industry.

Aquaculture liners Ideal for:

● Fish transport tanks and trucks
● Treatment and quarantine baths
● Land-based ponds and recirculating systems
● Offshore water storage and support barges
No matter if you run prawn hatcheries, salmon farms, or marine nurseries, our liners provide
clean and safe spaces. They help lower fish stress, improve water quality, and aid in disease
control.

Why Choose Fleximake Liners?

Our liners are precision-fabricated and CAD-designed to deliver:
● Seamless, hygienic surfaces to reduce disease risk
● UV, saltwater, and chemical resistance for long service life
● Leak-proof performance with fully welded seams
● Certified non-toxic to AS/NZS 4020:2018 standards (safe for aquatic life)
We include custom aeration and drainage fittings in our liners.

Our Fish Farming Liners Engineered for Australian Aquaculture Operations

Onshore Fish and Prawn Pond Liners

● Less disease outbreaks compared to unlined ponds
● Easier waste management with smooth liner surfaces
● UV-stabilised for high heat zones like QLD and NT
● Heavy-duty seams for larger biomass loads
● Leading Tasmanian salmon farms and onshore prawn farms across Australia use our
liners.

Salmon Farming Liners for Fresh Water Treatments

Fleximake liners offer a versatile solution for treating diseases in farmed salmon, right where
they are. You can use our fish farming tank liners in a couple of key ways:
● Convert Existing Net Pens: Easily transform your current netted fish pens into temporary
freshwater treatment zones. This means you can treat salmon diseases like sea lice or
Amoebic Gill Disease (AGD) onsite. This avoids the stress and challenges of moving fish
to land facilities. Fleximake liners are easy to install on the
● Equip “Wellboats”: Our liners are also ideal for outfitting vessels to create dedicated
“wellboats.” These special boats let you treat salmon with freshwater on-site while the
salmon stay in the sea water. This makes the process easier and reduces handling.

Transport & Quarantine Liners for Fish Farming Industry

● Leak-proof containment for live fish hauls
● Ideal for tankers, trucks, and offshore barges
● Quarantine-safe for new or sick stock of aquaculture species

Liner Materials & Lifespan

 

MaterialBest UseExpected Lifespan
TPUPrawn ponds, offshore tanks12–15 years
XR5Salmon, cold-water systems15–20 years
PVCBudget freshwater setups8–12 years

 

All our fisheries and aquaculture liners include:
● Welded seams (no glue or stitching) to retain water
● Custom-built ports and drainage fittings systems
● Patch kits for on-site maintenance

Benefits of Pond Liners in Onshore Prawn Farming

● Reduces Erosion & Sediment Buildup: Protects pond walls from aerators and water flow,
keeping the bottom clean.
● Improves Water Quality: Fewer oxygen dips and ammonia spikes for better growth
conditions.
● Lowers Nutrient Discharge: Less environmental impact from suspended particles and
nutrient runoff.
● Boosts Efficiency: Better survival rates, higher yield, and more stable pond
environments.


To choose the right liner for your prawn pond, match the liner to your pond’s size and shape to
avoid folds and waste buildup. Use saltwater-resistant materials like TPU or XR-5 for
high-salinity conditions.
If your system uses strong aeration, select liners with reinforced seams. Prioritise smooth liners
for easier cleaning and better biosecurity.
For long-term value, invest in thicker liners, which last significantly longer and reduce
replacement costs.
To ensure a successful installation, level the pond base. Remove rocks and sharp debris. Use a
geotextile underlay for extra protection.
Have all seams professionally welded. Poor seams can fail under pressure. Use DIY kits only if
you have the necessary experience.
To maintain the liner, clean it with prawn-safe products. Check it every year for damage,
especially near aerators and pond edges.

Solutions for Healthier Salmon Farms and Marine Aquaculture Systems

Our liners are vital for:
● Disease prevention during fish transfer and treatment
● Safe, medicated baths (hydrogen peroxide, freshwater dips, etc)
● Isolated quarantine tanks to contain outbreaks
● Compatible with oxygenation and water flow systems


Tasmania’s salmon industry is the most valuable of its kind in Australia. It produces more than 90% of the country’s Atlantic salmon. As people focus more on sustainability
and environmental care, using high-quality tank and pond liners is becoming essential.
This is especially true for land-based hatcheries and Recirculating Aquaculture Systems
(RAS).
As Tasmania develops better aquaculture systems, tank liners are important for clean,
efficient, and safe operations. They help farmers reduce disease and protect fish health.
They also lower environmental impact and improve long-term profits. This makes them
a key investment for the future of salmon farming.
