Bighead carp is actually very good table fare.
White meat, nice and flaky, mild flavor. Delicious battered and fried.
They do have bones in strange places compared to the fish species that most North American anglers would be familiar with, but butchering them is easy enough once you’ve done a few.
In the late 40's and early 50's we ate tons of these things because they were easy to trap in gill nets. They are bony for sure but taste very good. There are people on YouTube that show how to filet the carp so you can ignore the bones. Currently carp are an infestation of Oklahoma streams and lakes.
I fished the Neosho and Grand Lake for years but haven't been in that area for 50 years. The low water damn in Miami Oklahoma was the spot to snag spoon bill cats.
