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, […]

If you are pumping water from dams, rivers, creeks or channels into aquaculture ponds or tanks it’s essential that you filter your water to ensure you do not pump unwanted fish or their eggs into your pond.

Eel traps come in two colours either black or green, it makes no difference to the eels and just depends on what is available on the day. Traps are made in China, and it’s hard to designate and ensure we only get one colour. However, the colour of the trap makes no difference to the […]

Perimeter Fencing a Yabby Pond

Semi-intensive commercial yabby farming produces quantities of yabbies at far higher densities than occurs naturally in the wild. Ponds are built to specifications that suit the yabbies, shelter is added and food is supplied. All this is inducive to growing large numbers of yabbies quickly. Now the yabby Cherax destructor is one of the few […]
