Hi guys, new guy around the catfishin' world, and the only thing I've ever fished with is cut mackerel, a weight, and a little trout pole with some 8 lb. test. I'm working on upgrading the rig, as the fish I've been catching have been bigger, and too many snapped lines tell me that I'm doing something wrong. Two things I'm real curious about, and I'm looking for an explanation like I'm a 5 year old: 1. Trot lines. What are they? How are they used? What do they do? I tried a search, but they're all about details. I need the basics! 2. Live bait. How does one go about fishing live bait? I have access to catching a ton of blue gill and tiny small mouth bass, and I've heard they work, but how is it accomplished? Thanks in advance for any help, I'm looking forward to broadening my horizons and moving up the ladder to the big cats.
