I met a catfishermen at the boat landing. He was running trotlines. He mentioned that skipjack herring were running below the dam. Skipjack is a the greatest catfish bait known to man. I've never had much luck catching them. They live in the swift water below the dam, and my 12 foot jonboat has no business there.
Anyway this catman knew the full moon was nigh. Catfishermen are a different breed. They think more like meat fishermen: simple methods, simple gear, and simple and reliable equipment.
