Redclaw Crawfish Farming

The Australian redclaw crayfish are an excellent choice for aquaculture due to advantages in biological, physical, and commercial attributes. One of the primary advantages of redclaw for aquaculture is the lack of free-living larval stages, and therefore absence of a hatchery phase.

Using straight-forward production technology, this physically robust species has a simple life-cycle, requires simple foods, and is economic to produce. Production technologies are now well developed, and 'best practice' methods have been defined.

What is involved in farming the redclaw?

Site selection is the first step, and should involve assessment of several criteria which will maximize the suitability of the chosen site. A designed and systematic farm layout is important to minimize establishment and operational costs by utilizing gravity to fill and drain ponds, and to centralize facilities. Optimal pond specifications are 1000 sq.m , 1.2 to 2.5 m in depth and a V-shape that allows rapid and complete drainage.

Once all government approvals have been sought and an aquaculture license has been issued, the farmer may acquire crayfish from an established grower such as Stick-Fins Fish Farm.

Redclaw crawfish stock may be purchased as brood stock and used to generate juveniles for stocking to the operation, or as juveniles for immediate stocking.

Artificial shelters for the crayfish are essential. They should be abundant, and their shape, specification and positioning should permit water to drain out freely and completely as the pond is drained. Thick bundles of synthetic mesh and/or stacks of pipe material have been found to be the most effective.

Aeration is also essential. For redclaw aquaculture it is most often provided through airlift pumps, although other forms of aeration such as paddle-wheels and aspirators may be used. The aeration system should provide both oxygen input to the water and circulation of water from bottom to top and around the pond.
