Stocking your dam with Yabbies:

When you have a dam on your property there is nothing better than wandering down  to your waterhole, often with a coldie
 in one hand a net or two in the other returning
with a feed of delicious of blue claw yabbies

​Ensuring a continued supply of these delicious critters depends on the stocking density you started with, bearing in mind it wont only be you
snacking on these delicious morsels.

Water rats, eels, cormorants, herons, turtles, carp etc also have the humble yabby on the top of their menu

How many do I need?

The number of yabbies you will need is based on a number of factors
such as m2 size of dam, existing fish eels etc,
feed ie vegetation, bird life etc.

Adding 1 female and 1 male to a 1000 m2 dam is pointless
as they will likely never meet up.

 Dam Stocking Rule of thumb

To ensure a sufficient mix of males and females we recommend a minimum
of 1 yabby per 10m2 or 100 whichever number is greater
to build a sustainable population.

Better results are achieved at stocking rates of up to 3 yabbies per 10m2, bering in mind that dams need to have sufficient area and food resources for your yabbies to thrive.

Yabbies are not a schooling critter like fish and
require AREA not water volume.

Larger dams will produce bigger yabbies, as this reduces predation by other yabbies during the molting process required for their growth.

For this reason for dams less than 150m2 we recommend you call us for advice.

Through our own trials and feedback from other indicate that yabbies are not suited to aquaponic setups ie in IBC containers as as there is insufficient surface area
available and they'll just end up eating each other

 Food availability in the dam

Yabbies are detritus feeders able to metabolise meat and vegetable protein
meaning grasses, hay, bugs decaying leaf matter, vegetable scraps
are all ideal food sources.

Supplementary feeding with chicken or pig pellets
can also be of benefit.


Recent outbreaks of white spot virus in Queensland Prawn farms have been attributed to the use of raw eating grade prawns being used as bait.

For newly dug dams you will need to add a food source food such as
lucerne hay, meadow or mulch hay even sugar cane mulch
as soon as practical.

Hay is used by most commercial yabby farmers as a base food source. Lucerne hay is best however any hay is sufficient.
For small hay bales stake bale in dam until water logged them cut the ties and spread through out. Hay should be added at a minimum of
6 small bales per year per 1000m2. 


If you have fish/eels in your dam you should double
the Rule of Thumb number of yabbies.

Harvest Expectations

Stocking density also depends on how many and how often you want
to feed on these delicious critters.

If your idea is to have them as a main course rather than a garnish for a rib eye or scotch fillet we recommend double the minimum.

To give you an idea, commercially we stock our ponds
at 50 to 60 yabbies per 10m2.

Remember if you stock at a greater density you will need to increase feeding rates accordingly.
