Do yabbies need to come out of water?
Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water. The yabby has evolved an ingenious mechanism for surviving drought.
What do yabbies like eating?
Your yabbies will appreciate fruits and veggies too. Carrots, peas, potato peels, spinach and most fruits appeal to them. You could even treat them with some chicken pellets or a bit of lean mince every once in a while. Yabbies can live for months without eating, so feed them every one or two days.
Do yabbies have feelings?

How do yabbies mate?
Yabbies mate through an interesting process in which the male deposits a sperm package on the female's body near her first set of legs. After he places the sperm package, the female responds by releasing her eggs, usually no later than a day after she receives the sperm.

How do you purge yabbies?
Yabbies purchased from a Yabby Processor have been purged to empty the gut removing any muddy flavour. For those catching their own in their dams, it is important to purge the yabbies by leaving for at least 24 hours in a trap or 'yabby sock' (made from very open weave shade cloth) in a clean bottomed dam.
Are yabbies good to eat?
“Its flesh is best when cooked from live, in a fast-bubbling 44-gallon drum filled with salty water,” says Susman. “Refreshed in icy water, peeled and eaten with white bread, butter and brown vinegar, the blue yabby is manna from heaven.”
How do I grow bigger yabbies?
Trapping farm dams every six weeks reduces the density and increases the size of yabbies. Regular trapping can double the value of yabbies harvested from your ponds. Farmers usually sell all the market-size yabbies caught in their traps and return undersize animals to the dam.
Can you catch yabbies in winter?
You can catch yabbies year-round, but the best time to try is summer and early autumn. From late-autumn, through winter and into early spring, they bury themselves in the mud to conserve energy, mate and protect themselves.
