Hi Dr Bob,
Hi Bob
I have a major problem with my
pond. I am not sure exactly how many Koi, but I assume many
hundreds.
My pond is 12 feet deep center
and about 80 by 110 feet I will send you a few photos.
Can I put either a Catfish or some
other fish that will not harm my Koi in the pond?
It was dug 65 years ago, not lined
not filtered I do pump air 24/7 and add about 300 gallons
a minutes for an hour about twice week. I have an over flow
drain to add fresh water.
I live on nantucket Island.
By my calculations, you do not have a
pond. At 524,480 gallons, you have a small lake.
Considering that your pond is probably
a visiting point for countless marine and migratory birds,
you probably already have a sizable population of fish other
than your koi, their eggs brought in on the bird's feet
and feathers.
As long as you do not import predators
such as pike, bass or other game fish, your koi will be
fine. All you can do with volumes like that is exactly what
you are doing; aeration and fresh water. So far, I don't
perceive the problem. Most of my Midwestern ponding friends
would cheerfully commit major crimes for possession of that
body of water!
