The Aberdeen fishing hook has a long thin shank and is a popular choice among those fishing for such smaller game species as crappie and bluegill. The long shank makes removing the hook from these fish easier, since these species have an inclination to swallow a bait whole. The thin diameter of the hook allows you to slip them through live bait like shiners and minnows with minimum damage to the baitfish, which in turn keeps it alive longer.
Bait Holder Hook
The bait holder hook takes its name from the sharp but tiny barbs on the shank of the hook. These shanks help to hold in place live baits such as night crawlers and leeches that would easily slip down, and then off of, a normal hook. The Bass Pro Shops website states that the longer types of bait holder hooks are an excellent hook for young children learning to fish, as it makes the loss of their bait to nibbling fish occur less often.
Catch and release anglers lean toward the use of a circle hook, a hook with a barb that points inward, an exaggerated bend and a shortened shank. The idea behind this type of hook is that when the fish swallows the presentation, the bend of the hook forces the hook to the inside portion of the throat until it hooks into the mouth. This prevents the fish from swallowing the hook, which causes fewer deaths from gut hooking a specimen. The Learning How to Fish website states this is a hook catfish and muskellunge anglers employ quite often.
Offset Worm Hook
The offset worm hook possesses a 90-degree bend below the eye of the hook, followed by another where the shank begins. The function of this bend is to allow you to place plastic baits like worms on the hook in such a fashion that the lure will not slip downward. Offset worm hooks are the hook anglers use to create a Texas rig, where the plastic bait sits on the hook and the angler rotates the hook point to face the bait before burying the sharp point in the body of the plastic. This lets this presentation glide through heavy cover without snagging.
The treble hook has three bends and three points but just a single eye, in essence creating three hooks in one. Treble hooks typically hang from artificial lures such as spoons, crankbaits and plugs via a split ring. The treble hook increases the chances of hooking a fish that chases after one of the lures, which you usually retrieve in a rapid manner.
