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 blue claw yabbies

During construction of our new ponds 

dam stock supplies will be limited.

Orders filled on a first in basis, however
wait times are to be expected.

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 Yabbies 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 never likely meet up.

1. 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, bearing 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

2. 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. 

3. Predators

If you have fish/eels in your dam you should double

the Rule of Thumb number of yabbies.

4. 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.
