I own a carp lake and i wouldn't remove any from the lake and place into a home aquarium with other fish, there is no telling what diseases they might be carrying. Which is a shame, because the Tench and Crucian Carp spawned this summer and there where thousands of 50 pence sized fish gobbing around
What's your lake fish like bud ??
mind you, upon saying that, if you got a 2nd tank to act as a quarantine tank for a few months, i dont see why not.

main tank would have to be big though, like, real big for carp, they grow fast
