trotline

A trotline is a fishing rig consisting of a long main line to which many shorter lines are attached at intervals. These shorter lines, called droppers, are usually equipped with hooks and bait. The main line is anchored at both ends, often to the bottom of a body of water, and may be held in place by buoys or weights. Trotlines are typically used in rivers, lakes, and bays to catch bottom-feeding fish.

The design of a trotline allows for multiple baited hooks to be presented over a significant area. This increases the chances of a fish encountering a bait compared to a single hook and line. When a fish bites, the tension on the main line usually indicates a catch. Fishermen then retrieve the line, usually by hand or with a winch, to collect their catch.

Trotlines can be constructed from various materials, including nylon or monofilament for the main line and droppers. The size of the hooks and the type of bait used are typically chosen based on the target species. Common fish caught on trotlines include catfish, carp, and other species that inhabit the bottom of waterways. While effective, trotlines can sometimes entangle other aquatic life or boaters, and regulations regarding their use vary by location.
