Exactly, the water clarity is everything. I would mainly go on a feeder river to the Illinois, and would wait until later in the summer when the river calmed down and the water was super clear. You would be able to see bottom almost everywhere other than the channel. We would camp out all night, pound booze, and walk upstream to set them. I would either seine minnows or use chicken liver cut in half, baited on circle hooks and then dried in the sun to make it reek and harden on the hook. Going upstream was vital for doing them by wading, that way your milk jug marker bouy floated down to you and you wouldn't get tangled up. We would bait them up on a beach or sandbar strung out, and then just walk them in place next to down trees or whatever.
Everything was homemade using rope for the mainline and stringline for the drops, simply tied in a loop and then girth hitched on. Steel circle hooks so they will rust away if you need to leave a hook on, never use stainless. The circle hook is best because it guarantees a mouth catch, in the corner, everytime. The anchors were welded up steel scrap with an eye even lol. When checking the lines, you would simply walk back upstream, grab the bouy, and as you got to the fish you simply lowered them into a jumbo fish basket and cut the line with a knife, which would be easily retrieved later when dressing.
Turtles were fun, but honestly were often cut free because i was too drunk for that shit lol. We would also catch a ton of longnose gar, which we released too. Years later on a shutdown i got talking to another hillbilly fitter, who clued me in on the fact that the gar were better eating than the catfish! Apparently you take tin snips (i would imagine dedicated ones just for this) and go in their eye, cutting down the back. Then you can fillet them out, and when fried it tastes just like alligator. I haven't had the chance to try this out again, but next time i go I'll have to try it.
It's been years, a decade or more since I've gone out. We used to do them with canoes too, always fun doing that at night often with a healthy buzz on
I wanna try cooking up some of the Asian carp we have here, apparently they are the number one harvested fish on the planet by a very very large margin. Very firm white meat, like cod or tilapia, and since they eat plankton there's very little pollutants. I've had them before, pretty tasty. Up here they will literally just jump in the boat, but i want to try cast netting them too. I've done the bow and arrow thing while they jump, once again usually too "hydrated" for that!
