Gear that is attached to the end of a fishing line is called terminal tackle. This includes hooks, leaders, swivels, sinkers, floats, split rings and wire, snaps, beads, spoons, blades, spinners and clevises to attach spinner blades to fishing lures.

Fishing tackle can be contrasted with fishing techniques. Fishing tackle refers to the physical equipment that is used when fishing, whereas fishing techniques refers to the manner in which the tackle is used when fishing.

The term tackle, with the meaning "apparatus for fishing", has been in use from 1398 CE. Fishing tackle is also called fishing gear. However the term fishing gear is more usually used in the context of commercial fishing, whereas fishing tackle is more often used in the context of recreational fishing. For this reason, this article covers equipment used by recreational fishermen.

Hook, line and sinker is a classic combination of tackle empowering a fisherman to catch fish.

The use of the hook in angling is descended, historically, from what would today be called a "gorge." The word "gorge", in this context, comes from an archaic word meaning "throat." Gorges were used by ancient peoples to capture fish. A gorge was a long, thin piece of bone or stone attached by its midpoint to a thin line. The gorge would be fixed with a bait so that it would rest parallel to the lay of the line. When a fish would swallow the bait, a tug on the line would cause the gorge to orient itself at right angles to the line, thereby sticking in the fish's gullet.

A fish hook is a device for catching fish either by impaling them in the mouth or, more rarely, by snagging the body of the fish. Fish hooks have been employed for millennea by fisherman to catch fresh and saltwater fish. Early hooks were made from the upper bills of eagles and from bones, shells, horns and thorns of plant (Parker 2002). In 2005, the fish hook was chosen by Forbes as one of the top twenty tools in the history of man. Fish hooks are normally attached to some form of line or lure device which connects the caught fish to the fisherman. There is an enormous variety of fish hooks. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the hook. They are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of artificial, processed, dead or live baits (Bait fishing); to act as the foundation for artificial representations of fish prey (Fly fishing); or to be attached to or integrated into other devices that represent fish prey (Lure fishing).

A fishing line is a cord used or made for fishing. The earliest fishing lines were made from leaves or plant stalk (Parker 2002). Later lines were constructed from horse hair or silk thread, with catgut leaders. From the 1850s, modern industrial machinery was employed to fashion fishing lines in quantity. Most of these lines were made from linen or silk, and more rarely cotton.

Modern lines are made from artificial substances, including nylon, polyethylene, dacron and dyneema. The most common type is monofilament made of a single strand. Fishermen often use monofilament because of its buoyant characteristics and its ability to stretch under load. Recently, other alternatives to standard nylon monofilament lines have been introduced made of copolymers or fluorocarbon, or a combination of the two materials. There are also braided fishing lines, cofilament and thermally fused lines, also known as 'superlines' for their small diameter, lack of stretch, and great strength relative to standard nylon monofilament lines.

Important parameters of a fishing line are its length, material, and weight (thicker, sturdier 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.

Fishing with a hook and line is called angling. In addition to the use of the hook and line used to catch a fish, a heavy fish may be landed by using a landing net or a hooked pole called a gaff. Trolling is a technique in which a fishing lure on a line is drawn through the water. Snagging is a technique where the object is to hook the fish in the body.
