If you want to go the pond route another option is make a trophy fishing lake, it's been a thing in Europe for decades now. Look it up and you'll see dozens of different people have caught the same exact "record breaking carp".
Just fatten up some koi, some albino catfish, maybe even some sturgeon, let them go, and then charge people money to come catch them.
