Raceway & Trough Aquaculture Tanks

Raceway & Trough Aquaculture Tanks for Flow-Through Systems

Our raceway and trough aquaculture tanks are designed for flow-through and partial recirculating aquaculture systems, commonly used in fish hatcheries, nurseries, and juvenile grow-out operations. Their elongated design supports directional water flow, uniform oxygen distribution, and efficient waste removal—making them ideal for high-survival, high-throughput production.

These tanks are widely used for trout, salmon, tilapia, and fingerling production, as well as research and breeding facilities.

Optimized Design for Continuous Water Flow

Raceway and trough tanks are engineered to maintain stable hydrodynamics, allowing water to flow evenly from inlet to outlet.

Key design advantages include:

• Uniform water velocity across the tank length

• Improved oxygen distribution and reduced dead zones

• Efficient solid waste transport toward outlets

• Reduced fish stress through predictable flow patterns

This makes raceway tanks especially effective for high-density rearing and early life-stage production.

Durable Fiberglass Construction with Aquatic-Safe Gelcoat

All raceway tanks are manufactured from high-quality fiberglass (GRP) and finished with a gelcoat safe for aquatic life.

Material benefits include:

• Smooth, non-porous interior for easy cleaning and sanitation

• Long-term chemical and biological resistance

• Corrosion-free performance in wet environments

• Optional anti-bacterial gelcoat for enhanced biosecurity

The smooth interior surface supports fish health, water quality, and operational efficiency.

Modular Support and Reinforcement Options

Depending on tank size and site conditions, raceway tanks can be supplied with:

• Integrated or separate support legs

• Support structures made from galvanized steel or fiberglass

• Custom leg heights to accommodate drainage, piping, or slope requirements

Additional metal or plastic reinforcement profiles can be installed along the tank body and coated with polyester and gelcoat to improve structural strength and durability.

Custom Lengths, Widths, and Configurations

As a composite mold manufacturer, we are not limited to standard dimensions. Raceway and trough tanks can be produced to match your exact system layout.

Customization options include:

• Variable length, width, and depth

• Custom inlet and outlet positions

• Bottom drains, end drains, or side outlets

• Compatibility with flow-through or hybrid RAS systems

This flexibility allows seamless integration into new facilities or retrofits of existing hatcheries.
