Fishing

Line Fishing
A fishing line is a cord used or made for angling. Important parameters of a fishing line are its length, material, and weight (thicker lines are more visible to fish). Factors that may determine what line an angler chooses for a given fishing environment include breaking strength, knot strength, UV resistance, castability, limpness, stretch, abrasion resistance, and visibility.

Bow Fishing
Bow fishing is a method of fishing that uses specialized archery equipment to shoot and retrieve fish. Fish are shot with a barbed arrow that is attached with special line to a reel mounted on the bow. Some freshwater species commonly hunted include common carp, grass carp, bighead carp, alligator gar, and paddlefish. In saltwater, rays and sharks are regularly pursued.

Hand Line Fishing or Headlining
Is fishing with a single fishing line which is held in the hands. One or more lures or baited hooks are attached the line. Usually a weight and maybe a float are also attached. Headlining is one of the oldest forms of fishing and is still common.

The line can be jigged or moved up and down in a series of short movements, most often close to the sea floor. The motion attracts the fish, which are normally caught while trying to eat the lure but also as they move close to the jigged lure. The line is then hauled in and the fish removed. Headlining is most often used to catch ground fish and squid but other species are sometimes caught, including pelagic zone species.

Fly Fishing
Fly fishing is an ancient angling method to catch fish with artificial lures as distinct from live or dead bait. Casting the (practically) weightless lure requires a special fishing line and a long rod.

Fly fishing can be done in fresh or salt water. North Americans usually distinguish freshwater fishing between coldwater species (trout, salmon, steelhead) and warmwater.
