Basic pond aeration
Yabbies can tolerate very low levels of dissolved oxygen in the water. That said they may survive but they will not thrive and if your water quality deteriorates enough then they may die. Commercial farmers need to ensure that oxygen levels within any given pond never deteriorate to critical levels. Commonly, yabby ponds are large,…

Purging Blue Claw Yabbies, Cherax destructor and building a basic purging/holding system
Purging is a process where yabbies are stored and starved to allow the contents of their digestive system to be evacuated. The aim is to have the stomach and hindgut or wasteline through the tail empty before transport and sale. Purged and graded yabbies are generally considered superior to wild catch yabbies and attract a premium…

Perimeter Fencing a Yabby Pond
Semi-intensive commercial yabby farming produces quantities of yabbies at far higher densities than occurs naturally in the wild.

Now the yabby Cherax destructor is one of the few…
