Might be hard to read depending on the size of your screen but the side of the small boat says Gateway Blues Catfishing. Apparently there is a business that will take you out on the Mississippi searching for the critters, which are served fried. The river is a lot cleaner than it was some decades ago but, still, catfish are bottom feeders and the river is busy and just imagine what's down there. So, no, I wouldn't eat it.
Note the enormous size of the barges in the background, some distance behind the fishing boat. When in transit, they are connected two across and up to eight or ten long, pushed by a very powerful boat. How the pilots steer them through the many bends on the Mississippi is beyond me.
