Fishing lines

Fish are caught with a fishing line by encouraging a fish to bite upon a fish hook or a gorge. A fishing hook will pierce the mouthparts of a fish and may be barbed to make escape less likely. A gorge is buried in the bait such that it would be swallowed end first. The the tightening of the line would fix it cross-wise in the quarry's stomach or gullet and so the capture would be assured.

Fishing with a hook and line is called angling.

Trolling is a technique in which a fishing lure on a line is drawn through the water. Trolling from a moving boat is a technique of big-game fishing and is used when fishing from boats to catch large open-water species such as tuna and marlin. Trolling is also a freshwater angling technique.

Long-line fishing is a commercial fishing technique that uses hundreds or even thousands of baited hooks hanging from a single line.
