They're doing a public service.
Asian carp are an invasive species that is wreaking havoc on the Mississippi river's ecosystem. They will work their way into the great lakes which is going to be a disaster for fishing there.
They also jump out of the water if you drive a boat near them.
I live 15 miles from the mighty Mississippi...So I know all about these dang things! We have a redneck fishing rodeo held here every year at one of the lakes that is by the river. You can use anything but firearms or bows. Boat that catches the most fish win. Pretty funny seeing jon boats full of people armed with football helmets, baseball bats, and nets going out!
The carp have really hurt the fishing around here. We used to go stripe fishing around the dikes during the summer, and we used to catch tons of fish. I remember the first time I saw an Asian carp when I was younger...thought it was cool. Now they've grown to be a nuisance.
