Why is a trot line called a trot line?

A trot line is called so because it consists of a long line with multiple baited hooks attached at intervals, designed for fishing in a manner that allows it to "trot" along the bottom of a body of water. The term "trot" refers to the way the line is set up to move or be placed along a designated path, often with the intention of catching fish over a larger area. Traditionally, trot lines are used for harvesting fish like catfish, making them an efficient fishing method.
