Circle Hooks

Circle hooks are specialised single hooks for fishing with natural bait – fish fillets, dead bait, whole baitfish, live bait or other bait presentations. They are not a universal replacement for every saltwater hook, but a specific hook type for situations where the fish takes the bait, turns away and the rig comes under steady pressure. That is the main difference from a classic J-hook: when used correctly, a circle hook is not struck hard, but allowed to work through line tension, rod pressure and a controlled connection to the fish.

At SAF rybolov, we do not build this category only as halibut hooks for Norway. Circle hooks make sense wherever large fish are targeted with natural bait – in Norway, in tropical big game fishing and, in some cases, even in extreme freshwater fishing. The core logic is always similar: the right hook size, a strong enough rig, an exposed point, steady pressure and a bait that allows the hook to turn and work properly.

In Norwegian sea fishing, circle hooks are mainly used with fish fillets, pieces of mackerel, herring, whole baitfish or dead bait close to the bottom. Typical target species include halibut, cod, ling, hake and other larger saltwater predators. Circle hooks make very good sense in halibut rigs, dead bait rigs, paternoster rigs with natural bait and deep-water setups where the fish takes the bait under current, drift or steady pressure.

For active jigging, pilking or fast-worked soft lures, another hook type is often the better choice – a standard single hook, treble hook, jig hook or additional stinger. A circle hook is not a hook for everything. It is a specialist for natural bait fishing, where bait presentation and steady pressure after the take are more important than a sharp strike.

Circle hooks also have a very important role in tropical saltwater fishing. They are widely used for tuna, sharks, marlin, sailfish, kingfish, amberjack, grouper, tarpon and other powerful fish – especially in live bait fishing, dead bait fishing, chunking, drift fishing and charter big game fishing. In these situations, the hook is not only about setting the fish. Strength, rig balance, leader control and the way the whole setup behaves during a long fight are just as important.

A separate and very important group is formed by circle hooks with a swivel. These hooks make sense when the bait or the fish can rotate during the fight and twist the leader. Typical examples include tuna drift fishing, shark bait fishing and live bait or dead bait rigs for large saltwater predators. An integrated swivel helps reduce twisting in fluorocarbon or leader material and improves the rig in situations where a standard hook would transfer rotation directly into the leader.

The size of a circle hook should be chosen mainly according to the bait, not only according to the target species. A small fillet needs a different hook than a large mackerel for halibut or a bigger natural bait for tuna. The goal is not to use the largest possible hook, but a hook that has enough room to turn properly and does not have its point buried inside the bait. Hook sizes are also not completely identical across brands, so sizes such as 6/0, 8/0 or 10/0 should always be taken as a practical guide, not as an absolute standard.

For smaller and medium-sized baits, sizes around 5/0 to 6/0 usually make more sense. For larger fillets, halibut rigs, stronger Norwegian sea fishing and some tropical big game situations, sizes around 8/0 to 10/0 are often used. Sizes from 12/0 to 16/0 belong to very large baits, heavy setups and specialised fishing for large saltwater fish. The exact choice always depends on the specific model, hook gap, wire strength and the real size of the bait.

Correct baiting is also essential. If the hook point is completely buried in the bait, the circle hook may not turn correctly and its effectiveness can drop. The bait must hold securely, but the hook still needs room to work. It is equally important to avoid a hard strike like with a standard hook. After the take, it is usually better to wind into contact, let the fish load the rig and work with steady rod pressure.

Circle hooks are also used outside saltwater fishing, for example when targeting large sturgeon, catfish or other powerful river fish with natural bait. For SAF, this is more of a technical overlap than the main focus of the category, but it helps explain the broader logic of the hook: a circle hook is generally a hook for large fish, natural bait and steady pressure. With exotic, protected or regulated species, local rules and permitted fishing methods must always be checked before fishing.

If you are looking for circle hooks for saltwater fishing, choose them according to the bait and rig you want to use. A small fillet for cod calls for a different hook than a dead bait for halibut or a live bait drift setup for tuna or sharks. That is exactly why it makes sense to keep Circle Hooks as a separate category from general saltwater hooks – it helps you understand when this hook type is the right tool and when another hook style will work better.

Frequently Asked Questions – Circle Hooks

What is a circle hook?

A circle hook is a hook with the point turned inward toward the shank. It is mainly used for natural bait fishing, where the hook is allowed to work through steady pressure rather than through a hard strike.

What is the difference between a circle hook and a J-hook?

A classic J-hook is usually set with an active strike. A circle hook works differently – the fish takes the bait, the rig comes under pressure and the hook gradually turns into position. That is why circle hooks are usually not struck hard like standard hooks.

Are circle hooks suitable for halibut?

Yes. When fishing with a fish fillet, dead bait or whole baitfish, a circle hook can be a very good choice for halibut. The key is to choose the right size for the bait and to leave the hook enough room to turn properly.

Are circle hooks used for tuna and sharks?

Yes. In tropical and big game fishing, circle hooks are used for tuna, sharks and other powerful fish, especially with live bait, dead bait, chunking and drift fishing. In these setups, hook strength, correct size and leader twist control are very important.

What is a circle hook with a swivel used for?

A circle hook with a swivel helps reduce leader twist during drift fishing or during a fight with a large fish. It makes sense mainly for tuna, sharks and other fish that can rotate under pressure and transfer torque into the rig.

What size circle hook should I choose?

Choose the size mainly according to the bait. A smaller fillet needs a smaller hook, while a large baitfish or whole dead bait needs a larger hook. Hook sizes are not fully comparable between brands, so the numbering should be used as a practical guide.

Why should I not strike hard with a circle hook?

Because the hook is designed to work through steady pressure. A hard strike can pull the hook out before it has time to turn correctly. After the take, it is usually better to wind into contact, let the fish load the rig and keep controlled pressure on the rod.

Is a circle hook suitable for catch and release?

A circle hook can reduce the risk of deep hooking when used correctly, because it often works toward the corner or edge of the fish’s mouth. It is not an automatic guarantee. Hook type, bait size, fishing method and fish handling all matter.

When should I not use a circle hook?

A circle hook is not ideal for fast-worked artificial lures, active jigging or situations where you need an immediate classic strike. In those cases, a standard single hook, treble hook, jig hook or stinger is usually a better choice.
