Up until the 1980s carp were so hard to catch only the most detracted anglers tried, amazing that the $8 plus billon a year carp industry developed so recently
Strange, when I was growing up in the 70s carp were certainly not scarce or difficult to catch, we trot lined for them, pressure cooked and canned bunch of them. They were literally everywhere. Oddly trout and carp cook about them same, and while I don't categorically dislike trout, I do like a baked carp better than a trout.
