What is the known maximum lifespan for a yabby in protected environments?
Answer
Up to two decades
The potential duration of life for the common yabby can be quite substantial when the species is maintained in controlled and protected settings, such as specialized aquaculture facilities or dedicated home aquariums. Under these favorable conditions, some recorded individuals have been observed to persist for periods extending as long as two decades. This long potential lifespan, when combined with a relatively slow maturation rate, suggests that populations can be significantly set back by events that decimate the existing adult stock.
