TROLLING

method of fishing in which a lure or a bait is pulled behind a boat at varying speeds and depths of water according to the nature, habitat, and size of the fish being sought. Trolling is practiced in both freshwater and saltwater and with all kinds of craft; power boats to carry varied tackle and big-game gear are usually used at sea but also on inland waters, where legal. Trolling permits the fisherman to cover a wide area. Trolling for sport is usually done at relatively low speeds and with strong rods having nylon lines and heavy reels. The fisherman sits facing the stern, sometimes in a specially equipped fighting chair. Troll lines are also used by trawler fishermen for commercial catches, principally salmon and tuna.
