Fishing line

technology Maturity 5-7 Next article →

A fishing line is a flexible, high-tensile cord used in angling. Angling is the practice of catching fish using a hook-and-line setup. These lines act as a tether between an angler and a fish. They are often stored on a reel and pulled by a rod. A line functions much like an ultra-thin rope. Its effectiveness depends on attributes like length, thickness, and material. Other important factors include breaking strength, UV resistance, and abrasion resistance.

The process of catching a fish begins when a fish swallows bait or a lure. This action causes the hook to pierce the fish's soft tissues. The hook might anchor into the mouthparts, the gullet, or the gill. This creates a firm connection between the fish and the line. Once the fish is hooked, the angler pulls the line to bring the fish in. This final step is known as landing the fish. For very heavy fish, an angler might use a hand net or a hooked pole called a gaff.

Modern angling setups often use multiple sections of line joined together. The first section is the backing, which is the rearmost part on the reel spool. Backing prevents the mainline from slipping on the metallic spool surface. It also increases the retrieval speed and acts as a reserve for powerful fish. The next section is the mainline, which is the primary part of the line. It interacts with the rod, the line guides, and the reel. The mainline handles most of the tensile stress during retrieval.

The frontmost section is called the leader, which attaches to the hook or lure. Leaders are often thinner than the mainline to fit through the small eye of a hook. They are frequently made of materials with a high specific strength. Some leaders use fluorocarbon, which is a type of polyvinylidene fluoride (PVDF). Fluorocarbon is useful because its refractive index is similar to water. This makes the line harder for fish to see. Leaders can also act as a sacrificial device. If a fish pulls too hard, the leader breaks first to protect the more expensive rod and reel.

Materials used in fishing lines offer very different mechanical properties. Nylon is a common monofilament, meaning it is made of a single strand. Nylon is buoyant and can stretch under a load. This stretch helps damp the force when setting a hook or fighting strong fish. In contrast, braided lines, also called multifilament lines, offer great strength and a small diameter. They have very little stretch compared to nylon. Specialized fly lines may use a thick plastic sheath made of polyvinyl chloride (PVC). Some floating fly lines even contain microballoons to increase buoyancy.

Different environments require specific types of line for success. Trolling is a technique where lines are dragged behind a moving boat. This is used in commercial and big-game fishing to catch species like tuna or marlin. For toothy fish, anglers use wire leaders made of stainless steel or titanium. Stainless steel provides bite protection and abrasion resistance. Titanium-nickel alloys are also used because they are highly flexible and corrosion-resistant. These metal leaders can stretch up to 10% without permanent damage. This elasticity is perfect for setting a hook effectively.

History shows how much fishing technology has changed over time. In 1596, Leonard Mascall wrote about fishing with hooks and lines. During that era, people used silk and horse hair for their lines. By 1667, Samuel Pepys recorded that lines were made of catgut. Silk lines were also documented as being used around 1724. Today, almost all modern lines are made from synthetic polymers. These include nylon, polyethylene, and fluorocarbon. These artificial substances allow for much greater control and strength in various water conditions.
