What are Fish Baffles?
Fish baffles facilitate fish migration through man-made obstacles, allowing them to feed, spawn and thrive, which ultimately protects the ecological health of our waterways. They have also been strategically implemented to improve erosion control and flood risk management by reducing the velocity of concentrated water flows against riverbanks. Industrial Plastics fabricates High-Density Polyethylene (HDPE) baffles with custom specifications for your unique applications.
How are Fish Baffles used?
Man-made disruptions such as culverts and pipes create adverse water flow conditions and excessive sedimentation. Baffles are implemented in these structures to suit both high flow and low flow conditions.
High Flow: Baffles offer hydrodynamic control by reducing the velocity of water currents, creating shelter in the form of eddies and pools, thus minimising energy expenditure of migrating fish.
Low flow: Baffles offer hydrodynamic control by maintaining adequate water depth and hydraulic connectivity within the watercourse, thus promoting oxygenation of the water and fish longevity.
Whether you are part of a council undertaking waterway management initiatives or a farm-owner with your own waterways to protect, Industrial Plastics has the solution for you.

Why Our Solution Works
Historically, baffle solutions in Australia have used concrete and stainless steel. Concrete has proved to be problematic as it is a permanent and non-adjustable solution, lowering its efficacy when the surrounding environment changes. Concrete has also been seen to accumulate debris during flooding, necessitating expensive and frequent maintenance. Stainless steel is also susceptible to corrosion in saline or acidic waterways, significantly reducing its lifespan. Components of stainless steel, such as nickel and chromium may also leach into the water, posing a risk to fish health through the bioaccumulation of metals.
Our HDPE solution:
All these factors also enable our baffles to be easily moved to a different positions to experiment with different hydrodynamic controls.
- can be easily moulded into an array of shapes that suit a variety of different project requirements.
- boasts high chemical resistivity, which is especially important as baffles are exposed to the elements and subject to sewerage spills and overflow.
- has a 100+ year useful life, meaning it is recyclable and can be re-used in other projects.
- is extremely lightweight and affordable, making it simple to transport and install.
