Importance of calcium (alkalinity) in your
Pond, Dam or
Calcium is important for a yabby to form
a new shell and to molt successfully.
A yearly application of Agricultural lime
(NOT HYDRATED OR BRICKIES 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.
Happy Yabby Farming
