    Moving Koi during Torpor, is this a bad idea??

    My new project for lockdown 3.0 is to replace my pump fed pond with gravity fed, bottom drain apprx 9000 litres.
    I am very keen to get cracking but will need to transfer my fish from my current pond to a holding pond.
    Bearing in mind its the middle of winter, when will be a safe time/temperature to move my fish so that I can empty my old pond and start work?
    My current pond does not have a pump/filter connected during the winter.
    Any assistance will be much appreciated...

    Could be wrong there is going to be stress problems but if temp matched possibly Ok. Why is there no filter running over winter?

    Thanks for the response.
    My current pond set up is pretty basic and I never warranted running it during the winter.
    Now that I have more time on my hands, I can really dedicate my time to making this a proper hobby hence my doing this right from now on.

    A lot of carp (for fishing) are harvested and moved to new waters through the winter here in the UK. Although they are tougher than these pampered Japanese fish lol.

    You can do things to help with the stress of the move e.g. salt the temp pool you move them into (best to research this first as there are do's and don'ts when using salt).

    I'm guessing you are not feeding them. The issue you have is if you move them into a temp pool, they will still produce some ammonia, even without food.

    The chances are the biofilm in your pond is probably mature enough to deal with it on its own i.e. without the filter, in winter.

    But if you move them to a sterile temp pool, you will eventually get ammonia spiking, and that's even if you filter the water (which you'll need to due to lack of bio film in temp pool).

    I'd recommend using your current pond filters on the temp pool as they'll be mature. A new filter on the temp pool won't do anything to remove ammonia any time soon in these temps.

    So you'll need to test the water regularly in the temp pool. And carry out water changes as and when needed. Otherwise you could get a load of fish either become unwell, or worse still go belly up whilst you are still building the new pond.

    So I think it's doable, although others may advise against it.

    Just a few thoughts to consider.

    But good luck with it whatever you decide to do.

    Thats great, you are correct in that I am not feeding them whilst the pump/filter is not running.
    I will do some research on using salt .
    Very useful info!

    This would be a terrible time of year to move fish into a temporary tank imo.
    An unheated pond needs to be as deep and protected as possible to avoid temperature fluctuations and dangerously low temps.
    Will you be able to heat and insulate the temporary setup you have in mind?

    Koi don’t hibernate or have a ‘torpor’ in winter- they suffer if the temperatures are too low and lie miserably on the bottom until conditions become more bearable for them. It can put them under a lot of stress.

    Building a new pond and starting from scratch with the filters is a time of great risk for your koi. It’s best to do it at a temperature where filter bacteria can multiply, and you would be able to treat any parasite outbreaks that result from sudden changes in water and environment, as can often happen. If I were you I would hang on until spring, but get those filters running now and don’t turn them off again. It’s a miserable and muddy time of year to be digging right now too!
