No, unless you want the catfish to eat all your koi/goldfish--catfish grow fast and they will eat anything, including your other fish.
I have Blue Channel Catfish from about 1 inch two years ago, now 14 inches mixed in with both large and baby Koi. The Catfish eats the Koi food and interacts with them like nothing. I have never lost a fish. I think the key is getting a catfish when they are young and they can adapt, they're mostly bottom feeders and won't harm your Koi based on my experience. Make sure they start small though.
no werdos of corse not
Catfish eggs are fertilized by the male after being They must be goldfish eggs. It is nearly impossible to have catfish breed on their own in a tank or pond. Any fish female can have eggs, the eggs are fertilized after the female lays the eggs. So if the eggs hatch then most likely they be goldfish.

If I remember correctly, the Bumble bee catfish are more of a tropical fish and need a more controlled & warmer water temp. In your ornamental pond, I am assuming that you are going to be adding fancy goldfish which love cold water.
Catfish reproduce in a pond by laying eggs that are fertilized externally. The male catfish releases sperm to fertilize the eggs laid by the female catfish. The fertilized eggs then hatch into baby catfish, known as fry, which grow and develop in the pond.
Yes, catfish can reproduce in a pond environment. They typically lay eggs in nests that are built by the male catfish, and the eggs hatch into fry that grow into juvenile catfish.

The goldfish will eat the mosquito's larvae before they can leave the pond and fly.
Depends on the size of pond, what region you are in and what type of fish you are stocking what size fry you buy. Assuming a small pond with blue gill, catfish, small in size about $300-500.00.
One way to tell if there are catfish in a pond is by observing their behavior, such as seeing them swimming near the surface or feeding at the bottom. Additionally, you may notice catfish nests or burrows along the shorelines, which can indicate their presence in the pond.
