Fishing Terms Glossary

Fishing has a vocabulary problem. Almost everything written for anglers assumes you already know what drag, action, leader and slot limit mean — including, until now, most of this site.

This is those words in one place. Skim it, or use it when something else stops making sense.

---

Tackle: rods

Action — Where a rod bends. Fast action bends in the top third or less; slow action bends from the lower third into the handle. Not the same as power. → Rod action and power

Blank — The bare tapered shaft of a rod, before guides, handle and reel seat are fitted. It determines the rod's action and power.

Guides — The rings the line runs through along the rod. They spread load along the blank and keep the line following its curve. A grooved guide will cut line.

Power — How much force it takes to bend a rod, from ultralight to extra heavy. Independent of action.

Reel seat — The fitting where the reel clamps onto the rod.

Telescopic pole / whip — A rod that collapses into itself for transport. Common in Europe, less so in the US. Convenient; more joints means more failure points.

Tackle: reels

Bail arm — The wire loop on a spinning reel that flips over to lay line back onto the spool. Open to cast, closed to retrieve.

Backlash — A tangle on a baitcasting reel, caused when the spool keeps spinning after the lure has slowed. Also called a bird's nest.

Ball bearings — Bearings inside a reel. The count is heavily inflated in marketing; where they sit matters more than how many there are.

Drag — A stack of washers that lets line slip under load rather than break. The setting most beginners get wrong. → Fishing reels explained

Gear ratio — How many times the spool or rotor turns per handle turn. A 6.2:1 reel turns 6.2 times per crank. Not the same as retrieve speed, because spool size matters too.

IPT (inches per turn) — Line actually recovered per handle turn. The honest version of retrieve speed.

Spool — The part of the reel the line is wound onto.

Tackle: line

Backing — Cheap thin line beneath a fly line, filling the spool and giving reserve if a fish runs far.

Braid (PE) — Woven line. Almost no stretch, very thin for its strength, floats, most visible, weakest against abrasion.

Fluorocarbon — Line denser than water, so it sinks. Refractive index closer to water than nylon, so harder for a fish to see. Best abrasion resistance.

Leader — A short length of different line between main line and hook, for abrasion resistance or lower visibility.

Line memory — A line's tendency to hold the coiled shape of its spool. High memory means springy line, tangles and poor casting.

Monofilament (mono) — Single-strand nylon. Stretches a lot, drifts near neutral, cheapest and most forgiving. The beginner's line.

Pound test — Intended breaking strength under steady pull. Not the size of fish you can land. → Fishing line explained

Tackle: hooks and terminal

Barb — The backward point near a hook's tip that stops it backing out. Crimp it flat with pliers to make any hook barbless.

Circle hook — A hook whose point curves back toward the shank, so it slides out of the throat and catches the jaw corner. Do not strike it. → Fishing hook types

Hook eye — The loop at the top of the hook that the line ties to.

J-hook — The classic hook shape.

Jig head — A hook with a weight moulded onto it.

Shank — The straight section of a hook between eye and bend.

Sinker / weight — Anything added to get your bait down or hold it in current. Lead is restricted on some waters.

Snap — A small clip for changing lures without retying.

Swivel — A rotating connector that stops the terminal end twisting your main line.

Terminal tackle — Everything at the business end: hooks, weights, swivels, floats.

Treble — Three hook points on one shank, found on hard-bodied lures.

Weedless — A hook rigged or guarded so the point does not snag on cover.

Tackle: lures and bait

Chum / groundbait — Bait put in the water to attract fish to you rather than to be hooked. Legality varies sharply by state and water.

Crankbait — A lipped hard lure that dives and wobbles on a steady retrieve.

Cut bait — Dead bait cut open to release scent. Often better than live bait for catfish and sharks.

Dough bait — A paste or moulded bait for bottom-feeding species like carp and catfish.

Jerkbait — A slim minnow-shaped hard lure worked in twitches and pauses.

Live bait — Live baitfish, worms or crustaceans. Never move live bait between waters — a bait bucket is a primary invasive-species pathway. → Fishing bait explained

Popper — A topwater lure with a cupped face that splashes.

Soft plastic — A flexible moulded bait, rigged on a hook or jig head.

Spinner — A lure with a blade that rotates, creating flash and vibration.

Spoon — Curved metal that wobbles and flashes.

Suspending — A lure that holds its depth when you stop reeling, rather than rising or sinking. Deadly in cold water.

Swimbait — A soft body with a paddle tail that thumps on a straight retrieve. → Fishing lure types

Knots and rigs

Blood knot — A knot for joining two lines of similar diameter. Common in fly leaders.

Carolina rig — A sliding weight above a swivel, then a leader to the hook. Keeps bait near bottom while letting it move naturally.

Drop shot — Hook tied above a weight on the end, so the bait sits off the bottom.

FG knot — A slim, strong knot for joining braid to a leader.

Paternoster / high-low rig — Hooks on droppers above a bottom weight. Presents two baits at different heights.

Sabiki rig — A string of small baited hooks used to catch baitfish, not to fish for a target species directly.

Texas rig — A bullet weight above a hook with the point buried in a soft plastic, for fishing heavy cover weedless.

Uni knot — A versatile knot for tying line to a hook or joining lines. → Fishing knots · Rigs & setups

Water and places

Brackish — Water saltier than fresh, less salty than the sea. Where rivers meet the ocean.

Drop-off — A sharp change from shallow to deep. A classic holding spot.

Estuary — Where a river meets the sea. Among the most productive fishing environments there are.

Flat — A large area of uniformly shallow water.

Inshore — Fishing close to the coast, in bays, estuaries and shallow water.

Offshore / deep sea — Fishing well out from the coast, in deep water.

Reef — Hard structure, natural or artificial, holding a whole food chain.

Rip current — A strong, narrow seaward flow. Forms at jetties and piers, and persists even in small surf. Swim parallel to shore, never against it.

Seam — The line between fast and slow current. Fish sit in the slow side and feed from the fast side.

Slack water — The pause at the turn of the tide, when water stops moving. Usually the worst fishing of the cycle.

Structure — Anything that breaks up uniform water. Fish relate to it.

Tide — The rise and fall of sea level. Movement matters more than direction.

Turbidity — How cloudy the water is. It changes which sense a fish is hunting with. → How to read water

Technique

Bottom fishing — Presenting bait on or near the bottom.

Fly fishing — Casting a weighted line to deliver a near-weightless fly.

Jigging — Working a weighted lure vertically. The bite usually comes on the drop.

Spinning — Lure fishing with a spinning reel. The default method.

Surfcasting — Fishing from a beach into the surf, usually with a long rod.

Trolling — Dragging lures behind a moving boat. → Fishing methods explained

Regulations and conservation

Bag limit — How many fish you may keep per day.

Barotrauma — Injury from gas expanding inside a fish brought up from depth, typically 90 feet or greater. The fish often cannot swim back down.

Catch and release — Returning fish alive. A skill, not just an intention.

Creel limit — Another term for bag limit.

Descending device — A tool that returns a fish with barotrauma to depth. Required in Gulf federal waters for reef fish.

Possession limit — How many fish you may have in total, often double the daily bag.

Slot limit — A size range you may keep within — not below a minimum, not above a maximum. The maximum protects large breeders.

Spawn — When fish reproduce. Often restricted or closed to fishing.

Vessel limit — A cap per boat, separate from and sometimes lower than the per-person bag. → Catch and release, done right

The one that is not a word

"Check your agency." It appears on nearly every page here, and it means something specific: the state or federal body that manages the water you are fishing sets the rules, publishes them, and changes them. Not a magazine, not a forum, not this site. Every regulation we publish is dated and linked to its source so you can go and check whether it still holds.
