Hooks are the unsung heroes of fishing. So much thought goes into rigs, lures, rods and reels that most take their saltwater fishing hooks for granted. But the rest is a waste without good saltwater hooks. In some cases, you may be required by law to use a specific type of hook.

Fishing hook size is measured at the gap between the point and the shank. When considering what size and shape hook to use, consider the size and shape of the bait and the fish. Fish with small mouths will require small hooks. If you are using small pieces of bait or live bait, even for big fish, you may still want to use a small hook, as a larger hook may be difficult to hide in a small piece of cut bait, or could hinder the action of a live bait.

Saltwater fish hook sizes start at a tiny No. 32 and run up to a huge 19/0. From size 32 to 1, saltwater hook size increases while the number decreases. From size 1/0 to 19/0, the hook size increases along with the number. There is no standard in hook sizes, so one brand’s 3/0 may be larger than that of another brand.

While saltwater fishing hooks come in many sizes and shapes, they are generally made out of two materials: stainless steel or high-carbon steel. The first is corrosion-resistant but brittle, while the second will rust but is more forgiving of bends and twists. Both require care and maintenance to sustain. Sharpen fishing hooks with a file or hook sharpener and always rinse them with fresh water and coat with light oil between uses to help extend use.

J-Hook

J-hooks

J-hooks come in different styles for different types of saltwater fishing. Choose a hook that matches the size of the saltwater fishing bait you will use and the size of the fish that you will target. Some styles of J-hook work better with a particular species of fish. For example, summer flounder anglers prefer Kahle hooks because flat fish have a mouth that closes horizontally. Bait fishermen usually choose long-shank saltwater fishing hooks that are easy to remove from a fish’s mouth. Some types of hooks are specially designed to work with a particular type of bait. For example, offshore anglers use O’Shaughnessy hooks to rig ballyhoo baits.

The width of the fishing hook’s wire is also important. Use beefy hooks for big fish; a thinner wire on delicate baits like shrimp or worms. Hooks for artificial saltwater fishing lures are specially designed to work with a particular type of lure. Still, you may want to change the factory hooks with a different size or style hook to match your type of fishing. Saltwater fishing jigs should have a hook that matches the size of the trailer that you’ll use. When striking a fish with a J-hook, lift the rod tip straight up while reeling in any slack in the line. To avoid deep-hooking a fish (getting the hook down into the fish’s gut or gills rather than just the mouth), set the hook at the slightest tap on the line before the fish has a chance to swallow the bait.

Circle Hook

Circle Fishing Hooks

The birth of catch-and-release fishing spawned the invention of circle fishing hooks. These are shaped so that the point turns toward the hook shank, almost making a circle. Circle hooks are mostly used with live or cut saltwater fishing bait because the shape of the hook keeps it from becoming lodged in the fish’s gut. When a fish swallows a bait on a circle fishing hook and swims away, the line pulls the hook out of the fish’s stomach and into its mouth, where it will catch in the jaw. Circle hooks are almost foolproof. Instead of jerking the rod to set the hook, simply apply steady pressure until the hook finds its way into the fish’s mouth. Studies have shown that circle hooks dramatically reduce the number of fish that die after being released. In some fisheries, the use of circle hooks is even required by law. When fishing with natural baits, circle hooks just make sense.

Treble Hook

Treble Fishing Hooks

Treble fishing hooks work by snagging the fish when it hits a bait. Treble fishing hooks are sized the same way as other hooks, but it usually takes a smaller treble hook to catch the same size fish as a circle or J-hook. Most plugs use treble hooks so that when the fish realizes it has eaten a lure instead of a real fish, it is already hooked. Still, many anglers switch treble hooks for J-hooks on their lures to help protect the fish and their fingers. To change out the hooks, you’ll need a pair of split-ring pliers. Use the finger at the end of the pliers to pry apart the wires on the split-ring, then remove the old hook just like taking a key off a key ring.
