Calcium is important for a yabby to form

a new shell and to molt successfully.

A yearly application of Agricultural lime


on the banks around your dam will

ensure an available source of

calcium is always available.

Applying Ag lime on the banks of your

dam allows it to be gradually washed in

when it rains.

An indication that there may be a lack of

available calcium in your water

is that a great many of your

yabbies will have soft shells.

One or two soft shelled yabbies in a harvest

is acceptable as they may have

recently molted, however more

than that may indicate

a lack of calcium.
