Catfish here is a bog 1/0 hook with an 8" creek chub for bait and about 2-3 ounces of lead 24 inches up the line. Cast it out, put it in the river bank rod holder and kick back in the lawn chair and have a couple beers while waiting. Listen to something on the radio... also done after 9pm and often we sit out until 3AM or later...
Tackle for fresh water depends on species and fishing mode.. trolling requires its own set of lures/rigs, bank fishing can be bottom or bobber fishing and as simple as a slip bobber, split shot, and a hook sized for the fish...
Trolling here means walleye or northern pike, I tie my own spinner rigs for that.
