Stocking your dam with Yabbies:
DO NOT FEED UNCOOKED SEAFOOD TO YOUR YABBIES.
Yabbies need AREA not volume.
The number of yabbies you will need to build a sustainable population is primarily based on square metre area of your dam.
Yabbies are a solitary animal, not a schooling one like fish and are opportunist feeders meaning every yabby is a potential meal for another yabby, especially during the molt process.
Rule of thumb
Adding 1 female and 1 male to a 1000 m2 dam is pointless
as they will likely never meet up.
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.
Aquaponic systems or water bodies less than 150m2 are not suitable if you are seeking to grow a constant and sustainable supply of yabbies.
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.
Healthy dams or water bodies are those which can support an interconnected food web, as demonstrated in the image below

Supplimenatry feeding with chicken or pig pellets can also be of benefit.
The outbreak 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.
