Today's Pond Q&A

In this issue:

- BATHING BIRDS - WILL THIS HARM THE FISH?

- ALBINO CATFISH - CAN THEY WITHSTAND WINTER
TEMPERATURES IN ONTARIO?
-----------------------------

Question>

Hello Carolyn,

My question is this, I have a small pond with a waterfall, all
very nice, The Blackbirds and Sparrows keep bathing on the
waterfall, Is this OK or will any problems arise from them
bathing, i.e. any bugs from the birds falling into the pond.

If this is a problem, how do you suggest I keep them away?

Regards,
Malcolm Hills

Hi, Malcolm.

I do not see the birds as a problem to the health of your fish.
At least as far as their bathing, that is. The only problem
comes from their droppings and there is, unfortunately, no way
to prevent bird droppings from entering an outdoor pond.

There are some precautions you can take, such as bird netting
over the pond, but it may take away from the appearance. If your
filter is working and is charged with the nitrifying bacteria,
you should not have anything to worry about. The bird poop will
be handled by the filter in the same manner as the fish poop.

The birds to worry about are the predatory ones, like heron and
egrets. But a blackbird should pose no problem.

Hi Carolyn:

Just wondering if you know anything about Albino
Catfish? We have 2 of them in our pond - doing great.

What I need to know is if they can take the winter or do they
have to be moved to a tank indoors over the cold spell?

We live in Southern Ontario.

Thanks,
Connie

Hi, Connie-

I have had albino catfish myself and they did not do that well in
New York winters. Mine lasted about two years, but the second
year the winter was terrible. The fish didn't make it.

I believe if you have enough depth to the pond to create the
thermal inversion, with the warmth at the bottom, or use a
floating heating element in the pond if it is a smaller pond, the
fish might be alright. Mine was a small pond and I probably was
not able to offer proper protection at the time.

You need to decide whether you have the depth to prevent
fluctuations in temperatures, if the fish is large enough to
sustain lower temperatures, if the pond is large enough to offer
frost-free areas, and if the fish is in good health before going
into the winter.

These are the criteria that will determine whether the fish
should remain outside or be brought in.
