Welcome to ACH, The Australian Redclaw Crayfish Hatchery

ACH is the home of the world’s most advanced crayfish hatchery, producing the healthiest, strongest, fastest-growing Australian Redclaw crayfish. Cherax Quadricarinatus

The Australian Redclaw Crayfish

The crayfish species we hatch at ACH is Australian Redclaw Crayfish (Cherax quadricarinatus) or simply Redclaw.


Redclaw are native to freshwater streams and lakes of Northern Queensland and the Northern Territory of Australia. A highly fertile and very tolerant of a broad range of environmental conditions and changes, Redclaw is also known to have a simple reproductive cycle and fast growth rates. As such, Redclaw became highly popular aquaculture for commercial farming.

Our Hatchery

Dr Elliott is happy with the latest diagnostics

The Australian Crayfish Hatchery is not only the world’s first hatchery, specifically established to solve industry-wide hatching losses, it is also the most advanced of its kind. 

Its highly-trained staff, led by Dr Lisa Elliott PhD, regularly deploys the latest disease monitoring and management techniques, resulting in proven significant decrease in mortality rates, increased survival rates, and overall healthier, antibiotic- free and and specific pathogen-free redclaw crayfish for the benefit of all stakeholders down the supply chain, be they growers, restaurateurs and consumers. 

We Hatch Craylings

What’s a Crayling?

A crayling is short for a crayfish hatchling. Redclaw crayfish undergo several larval stages after hatching before reaching a stage that resembles a tiny crayfish. This is the first juvenile stage of the crayfish and is termed the crayling stage (previously termed S3J). Each crayling is approximately 0.02g and 10mm.

ACH has been selling disease-free premium craylings to both local farmers in Australia and international buyers since 2016.

What Sets Our Hatchery Apart?

Superior Broodstock

Eggs are sourced from selectively bred redclaw for superior growth and disease resistance and hatched at ACH’s state-of-the-art hatchery facility.

Biosecure Lab

Water quality, health and disease management are carefully monitored and controlled onsite in a specialised, purpose built, customized biosecure laboratory.

Pathogen-Free Craylings

ACH craylings are cultured in a pathogen-free, state-of-the-art hatchery facility—the first of its kind in the world

Antibiotics-free Craylings

Australian Crayfish Hatchery (ACH) do not use antibiotics to treat eggs

Same age/size batches

ACH craylings are supplied in batches of the same age/size, thus significantly reducing size variations at harvest.

Batch-in, Batch-out' Stocking Method

ACH supplies craylings in batches suitable for stocking individual ponds, thus eliminating many of the costs associated with current stocking methods.

Crayling Production is ACH's Core Expertise

The Townsville-based Australian Crayfish Hatchery, in short ACH, sets a world standard in Redclaw crayling production, covering all aspects involved in the hatching process, including sourcing, selection, diagnostics, disease management, feeding, larvae rearing, storage and shipping to customers nationwide and globally.  

All craylings leaving ACH’s premises to grow-out farmers are healthy, disease-free, antibiotic-free, and overall more resilient than any known craylings out there.  

Why Purchase Craylings from ACH?

We’ve been selling craylings both to local and overseas farmers since 2016. Over and beyond all the advantages featured in ACH’s lab, here’s why you should seriously consider switching to ACH’s ‘Batch-in, Batch-out’ (BIBO), same age, same size, disease-free premium craylings, with which to stock your ponds

  • Optimize your resources;
  • Improve your productivity;
  • Plan reliably for growth;
  • Improve your profitability.

Ordering ACH's Premium Craylings

Minimum orders: We sell in batches of 10,000 craylings, which is the standard number for stocking a 20 x 50 metres pond. As a rule, we request all buyers to place written orders at least four (4) weeks prior to their requested delivery as craylings are typically ‘cultured to order’. 

Volume Discount Pricing: Typically, large orders (e.g. in excess of 100,000 craylings) will qualify for  volume discount. Note that fully-paid advanced orders (i.e. 6 to 12 months in advance) will qualify for volume discount. Contact us for details. We’ll do our best to accomodate your requirements. 

The Future is Bright and it's Vertical

Born Out of Necessity

ACH’s planned breeding facility is moving away from traditional breeding practices into the future, a vertical future that is. Like our state-of-the-art lab and hatchery, our intensive breeding facility will be a world-first, wholly dedicated—albeit initially—to the Australian redclaw crayfish.

Indeed, the Future is Bright

By going vertical, we aim at unlocking the industry’s most acute stumbling block—namely a steady supply of eggs—and produce large numbers of quality eggs selected from superior genetics all year around, fully monitored for climatic and seasonal factors, all under one roof.

The Future is Now

ACH’s first intensive breeding unit is well on its way. All its components are currently being manufactured while we’ve been hard at work building the skeleton infrastructure to support it all, including all utilities necessary for smooth its operation

What’s wrong with current redclaw crayfish stocking practices?

Known Inefficiencies with Current Stocking Practices Stocking numbers are dependent on the numbers of berried females, which makes it difficult to predict stocking numbers.Current stocking practices are not conducive to control of genetics, which leads to inbreeding issues. There’s neither control nor accurate information on stocking density, size variations or survival rates, which respectively and
