not an authority on the matter but sturgeon river fish or delta fish and get very big.

As the title states, I'm looking for a large growing fish like a mahseer or something similar that can survive a cold NJ winter. I'd like to put something different in my koi pond. It gets cold enough to freeze over if I didn't have one of the pumps and the air pump running all winter. Are there any fish that can/will survive? Also cant be too aggressive. Don't want it to beat up my koi. The pond is 22'x18' and 40" deep. Any ideas are appreciated.

Just be careful. There are cold water and tropical mahseers. Tropicals will definitely not make it.
Speaking from my experience with a small puddle pond in Socal, Indian mahseers does fine. However, they did eat all the fins and tail off my daughter's goldfish. Poor thing could only bob around. Can't speak for ponds in NJ. GL

Thanks for the link Chicxulub. I'll check it out. I want to stay away from sturgeon or paddles. Although my pond is large for a suburban backyard pond, it wouldn't be right to have fish that large in there.

Putitoras or kudrees are fine but tambroides or the other thai mahseer seems to be a little bit more sensitive

I've had an albino channel catfish in my two foot deep pond for the last two winters in CT and he's doing great.
I do keep a small pump at the surface to try and keep it from freezing solid but it still froze a couple of times for a few days. I'd say he's about 18 inches now and has never bothered my Koi or Comets.
