It is typically made of nylon, silk, or other materials and is used to connect the fishing hook to the fishing rod. Fishing line comes in various sizes and strengths, depending on the type of fish being targeted and the fishing technique being used.

The most common types of fishing line include monofilament, fluorocarbon, and braided lines. Monofilament lines are made of a single strand of material and are known for their stretch and flexibility. Fluorocarbon lines are more resistant to abrasion and have a lower visibility in the water, making them ideal for fishing in clear waters. Braided lines are made of multiple strands of material woven together, providing high strength and minimal stretch.

When selecting a fishing line, it is important to consider the type of fish being targeted, the fishing environment, and the fishing technique being used. It is also important to regularly inspect and replace fishing line, as it can become damaged or weakened over time.

Overall, fishing line is an essential component of any angler's gear and plays a crucial role in the success of a fishing expedition.
