Moray Koi are now following the Dealers Protocol by Dr Paula Reynolds of Lincolnshire Fish Health Laboratories .
This lays down the Koi husbandry methods and practises that maintain Koi in peak condition in an optimum environment and ensures that Koi keepers can be confident in purchasing quarantined healthy Koi .
As we always tell everyone, you do not keep Koi, but you keep the water. All of our ponds and tanks are checked at regular intervals for pH, Ammonia, Nitrate, Nitrite, Oxygen, KH (Carbonate Hardness) levels and all readings recorded along with any factors that may have affected the levels for that day, for example, immature filter, water changes, rain (for outside ponds), the use of pre-filter filters (for example if running a trickle filter, filtering the water from the source), etc. We also monitor the same levels in our own tap water as a further reference point. Our water is tested at the point that it enters filtration from the bottom drains. Ideal levels and corrective procedures can be seen in the following table:
OUR QUARANTINE PROCEDURES
We are fully approved by DEFRA to transport Koi and, as part of this approval, our Quarantine Procedures have been reviewed and approved by them.
DEFRA recommend that the minimum quarantine period should be two weeks at 23ºC to 28ºC, although they stress that this is the very minimum period – our Quarantine Period is between five and seven weeks.
The initial temperature that Koi are acclimatised to, when they arrive with us, is 15ºC. This temperature is then raised by 1ºC, per day, until a maximum of 28ºC is achieved. This temperature is then maintained for a maximum of three weeks, with the Koi being closely monitored, in particular, looking for any signs of virus, infection, behavioural changes, etc. Once satisfied that the Koi are stable – i.e. at the end of the maximum of three weeks at constant temperature, the temperature is then reduced back to 15ºC at 1ºC per day. This process is then repeated and then the Koi are transferred to the pond ensuring that they have been acclimatised to any differing temperatures accordingly.
During the Quarantine period, any fish that have been purchased in advance, are kept at our risk. Should the new owner require us to keep their fish outwith the Quarantine period, this then becomes at their risk.
