The freshwater hook guide: shapes, gap and what each is for

People spend a lot of time choosing lure colors and almost none choosing the hook, but the hook is the part that has to do the job. Its shape decides how well a bait sits on it, how it comes through weeds and wood, and how often a fish stays on. This guide explains hook parts and the main freshwater styles in plain terms. Where we found a maker, magazine or agency saying something specific, we say who, and where we found only opinion, we say that too.

The parts, and what the size means

Wikipedia's overview of hooks says sizes run from 32 (smallest) to 20/0 (largest), with size 1 in the middle, so a bigger whole number means a smaller hook until you reach the "/0" sizes, where a bigger number means a bigger hook. The numbers mostly reflect the gap, and the article notes there is no international standard, so the same size from two makers can differ. Makers also mark hooks with codes such as 2X heavy or 3XL (extra long). Check each maker's chart.

Soft plastics: round bend, straight shank and wide gap

The Ontario Federation of Anglers and Hunters published Jeff Gustafson's hook choices in July 2026. For a Texas-rigged slender worm he prefers a round-bend hook, which he says gives a more natural presentation, and for larger soft plastics he uses an extra-wide-gap (EWG) style. He sizes up to a thicker, heavier hook when he fishes heavy rods and braid. For Texas rigging in cover he uses a 2/0 or 3/0 straight-shank hook.

You will read strong opinions on which of these hooks up more fish. We could not find a controlled test, and the fishing forums we looked at disagree, so we do not claim one style hooks more fish than another. The safest rule is the one pros use: match the gap to the bulk of the bait, and make the wire strong enough for your rod and line.

Finesse: drop shot and wacky

Gustafson says light wire is the choice for finesse presentations. For drop-shotting small baits nose-hooked for smallmouth he uses a #1 or #2 drop-shot hook, and for minnow baits a straight-shank hook in 1/0 or 2/0. For the wacky rig he says the technique calls for a light or medium-gauge hook, and his top choice is a 2/0 wide-gap weedless hook, sizing up for bigger fish. Light wire lets the bait move freely, but a light hook can also straighten under a big fish, so match it to your line and rod.

Live bait and panfish: the Aberdeen hook

In-Fisherman's 2017 article on Aberdeen hooks quotes Eagle Claw's Matt Gray saying they are tempered to be a little softer, so they bend out easily when you hang up in brush, and that they keep their strength when bent back into shape. The article says the thin wire keeps live baits lively and can be removed readily thanks to the extended shank. It says photos show an Aberdeen style being popular from about 1859, that Aberdeens are popular for crappie and perch and, in smaller sizes, for sunfish, and that most are available from #8 to 2/0, with #2, #4 and #6 the best sellers. For stocked trout, TPWD's winter trout tips prefer longer-shank hooks from #8 to #4, with #6 ideal.

Treble hooks, barbs and the fish you release

Hardbaits often come with treble hooks, and replacing them is a common upgrade. When you do, pick a hook of the same size and weight, since an oversized treble can change how the lure swims; this is general advice, not a measured rule. For releasing fish, the large 2005 review of catch-and-release studies found no statistically significant overall effect of treble versus single hooks or of hook size, and found barbed hooks had marginally higher mortality than barbless ones. TPWD says to bend down the barb, because it makes removing a hook easier, from a fish or from you.

Barbs: mash them down with pliers before you fish. TPWD says a barbless hook is easier to remove and does less damage, which matters most when a child or an angler without much experience is the one holding the rod.
