I
have a small fish pond in Canada with koi that have grown
to a pretty good size. They are too big to bring inside, so
I would like to keep them outside. Will they freeze or hibernate
or something or will they die?
If your pond is less than 4 feet deep,
your fish will not survive a Canadian winter, no matter what
you put on the bottom of the pond. Koi are cool-water fish,
they can handle temps down to 38 degrees F, but lower will
stress them too much to survive. Some Options:
- Erect a small poly house over your pond
and keep it heated with a space heater through the winter,
enough to keep the water from icing over completely.
- Get a large vat (600 gallons) from
Aquatic Eco-systems and set it up in your basement along
with the filter from your pond. Figure on 20-25 gallons
of water minimum per inch of koi in the vat.
- Find a pond enthusiast friend with
a big deep pond and board your fish with him for the winter.
