Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side, eg when fishing from a jetty. Trolling is used to catch pelagic fish such as salmon, mackerel and kingfish. Trolling can be phonetically confused with trawling, a completely different method of fishing, where a net (trawl) is drawn through the water instead of lines. Trolling is used both for recreational and commercial fishing whereas trawling is used mainly for commercial fishing. 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. Trolling from a moving boat involves moving quite slowly through the water; this may be accomplished by use of a special trolling motor.
