Do you think the guy in this video is super cooling his koi?
I don't see anything funny about frozen koi.Does the photo have anything to do with the video? Or are you just making a funny?
THE only problem he might have is that the water below the ice could be displaced as it is turned into a mountain of ice above the pond. You could run a hose every week from the house and top off pond, which is probably what he did, as I have to top ponds up every week due to evaporation. The method does work very well for CE and many others.Hopefully we can all agree his water would stay warmer if he just let the pond freeze over. But... keeping water warm isn't the only thing needed to keep fish safe during a winter shutdown. On the plus side, he is removing harmful gasses and is introducing new oxygen into the water.
I didn't actually see any fish but if taken at his word this approach has not killed any fish in the 15 years he's been doing it. Since koi can survive at water temperatures fairly close to freezing, one can assume his water is never getting colder than that.
That said, it's not something I personally would recommend as a generally-applicable solution. If he lived in a colder/windier climate he might end up having problems.
The UK has a prolonged period of borderline temps for koi, where fish are barely active or have any effective immune system, while parasites and diseases are still active and the fish are vulnerable
Colleen your waters are colder longer when both fish, diseases and parasites are not active
Or maybe it would be a good reason for cooling it.I would agree with that.
If the UK water temperatures are constantly fluctuating above and below the temperatures where parasites are active, I could see where the koi are at a disadvantage in UK water temperatures, so keeping koi in Canada is easier, not more difficult.
That would be a good reason for heating pond water in the UK.
