A collection of fishing rods A fly fishing rod Line guides on modern fishing rods Fishing with a fishing rod. A fishing rod or fishing pole is a long, thin rod used by anglers to catch fish by manipulating a line ending in a hook (formerly known as an angle, hence the term "angling").
The basic technique is to quickly flick/swing the rod forward towards the water, with the inertia of the tackles lagging and bending the rod backward (i.e. "loading" the rod), and then use the "springing" (elastic rebound) of the rod to "hurl" and rapidly sling the line forward, which in turn will launch out the hook and bait.

Most adult female ceratioid anglerfish have a luminescent organ called the esca at the tip of a modified dorsal ray (the illicium or fishing rod; derived from Latin ēsca, "bait"). The organ has been hypothesized to serve the purpose of luring prey in dark, deep-sea environments, but also serves to call males' attention to the females to ...
During the day, trawls at depths between 350 and 600 m (1,100 and 2,000 ft) produce the highest catches and at night the greatest abundance of fish is in the depth range 170 and 400 m (600 and 1,300 ft); this indicates that some, but not necessarily all, fish make short daily vertical migrations.

Larger perch are often caught on large live minnow on a jighead, especially when fished over weed beds. Bobbers, if used, should be spindle type for the least resistance when the bait is struck, but small, round bobbers work well, too, yet indicate any slight pull of the bait. Raising the rod tip is usually more than enough force to set the hook.
Electrofishing relies on two electrodes which deliver direct current at high-voltage from the anode to the cathode through the water. [2] When a fish encounters a large enough potential gradient on this path, it becomes affected by the electricity.
A very different technique uses land based kites, instead of boats and rods, as the mechanism for delivering the terminal tackle at the end of a fishing line. This method has been used to catch mahi-mahi from cliff tops in Hawaii. [7] In French Polynesia, mahi-mahi are caught with a harpoon. Mahi-mahi don't dive when they are pursued.
Emerging research suggests catch and release does not work very well with fish caught when deep sea fishing. Most deep sea fish species suffer from the sudden pressure change when wound to the surface from great depths; these species cannot adjust their body's physiology quickly enough to follow the pressure change. The result is called "barotrauma
