Here at Cedar Lodge Koi we follow a strict regime
to avoid disease in all of our koi.
With the rise in incidence of Koi Herpes Virus
(KHV) in the past few years, we have taken a strong
line to be certain that the koi we sell have the
lowest possible chance of being infected with
KHV which in turn offers peace of mind to you
our clients.
Here is how we recommend that you should quarantine
your koi.
The procedure we follow is:
You should have a separate tank and filtration
away from your main pond (so no cross contamination
can take place) you should have separate nets,
bowls and koi handling equipment.
When you take your new koi home, the first thing
to consider is temperature acclimatisation for
an hour by floating the bags in the host tank.
The koi should then released from their bag into
a bowl and tank water is slowly introduced to
the bowl. This not only allows the koi to the
altered water conditions but also allows them
to 'dump' their accumulated ammonia. They are
slowly water changed in the bowl over an hour
and then taken out of the bowl and released into
their quarantine tank.
The koi should be systematically screened for
parasites over the next three weeks and treat
accordingly.
After 3 weeks of being held at temperatures of
at least 23°C you need to cool the tank down
to 15°C. This is done to stress the koi and
initiate the KHV if it is present. The most common
response is an outbreak of White Spot which you
should treat immediately.
The temperatures are allowed to rise again (to
at least 23°C) and after another 3 weeks the
koi are considered clean.
This is the shortest period of quarantine we recommend,
if you add any other koi to the tank during the
quarantine period then you should recommence the
six week period for all of the koi present in
the tank.
Throughout this quarantine period feed the koi,
on a high quality diet except when they are being
medicated.
