Well, I caught most of them on a Mepps spinner. 75% were mouth hooked. I don't know if they were trying to eat it or if it somehow ticked them off but they actually struck pretty hard.
The mottles ones are Bighead Carp, the silver ones are Silver Carp
This is the tailwaters of Carlyle Lake in Illinois
With bones removed ( lots of Youtube vids on how) the meat is white flaky and delicious. The roe is also excellent eating.
They fight like freight trains and are tons of fun to catch
