If you keep fish to eat, how you kill them is not a detail to skip over. A fish left to suffocate in air or on ice dies slowly and stressed, and that stress floods the flesh with lactic acid, softening the meat and shortening how long it keeps. A quick, correct dispatch is both the humane thing to do and the single biggest improvement you can make to how your catch eats. The tools for it are simple: a spike to destroy the brain, or a priest to deliver one firm, clean knock.
The tools below cover both approaches, from traditional priests to iki jime spikes and full kits. What follows is how they differ, how each is used, and how to choose the right one for the fish you keep.

Choosing the Right Tool
The choice starts with the fish you keep and where you land them. A priest, essentially a weighted club, is the fast, foolproof option for a firm knock to the head and works well on the deck of a boat or the bank. An iki jime spike gives the cleanest, most humane result by destroying the brain instantly, but it asks that you know where the brain sits on your target species. Match the tool to your fish and your confidence, and there is no shame in carrying both.
An iki jime spike is a rigid, pointed rod driven into the brain for an instant, humane kill that also gives the best possible meat. The key is the spot, which sits above and behind the eye and varies with the species, so it pays to learn it for the fish you target. The spike needs to be long and stout enough to reach the brain of your biggest fish; a thin, short spike that suits a small fish will not do the job on a large pelagic. Rigidity and a sharp, corrosion-proof point are what make it work.
A priest is a short, weighted club used to stun and kill with one firm blow to the head, just above and behind the eyes. Its virtue is simplicity: there is no anatomy to find, and it works fast on a lively fish that is awkward to hold still for a spike. The weight is what matters, since a light club needs several blows while a properly weighted one does the job in a single, clean strike. Wood, brass-weighted and lead-cored versions all work, provided they carry enough mass for your fish.
Whatever you choose lives in a wet, salty environment, so build quality decides how long it lasts. A stainless or otherwise corrosion-proof spike keeps its point instead of rusting blunt, and a sealed or solid priest will not swell, split or rot. A secure grip that works with wet, bloody hands is a safety feature rather than a nicety, and a lanyard or sheath keeps a sharp spike from becoming a hazard loose in the boat. Simple and well made beats clever every time.
Dispatch is only half the job; bleeding the fish straight afterwards, by cutting or breaking the gills, drains the blood that would otherwise taint and shorten the life of the meat. Spend on a corrosion-proof spike or a properly weighted priest, since a blunt spike or a light club fails at the crucial moment, and save on combo gadgets you will not use. The mistakes to avoid are guessing at the brain location and half-killing the fish, using a spike too small for the species, and forgetting to bleed and chill the catch, which undoes the good work the dispatch just did.
Knowing the brain location. A spike only works if you hit the brain, and the spot differs by species — generally found by driving the spike in just above and behind the eye toward the lateral line. A done-right spike produces an instant, obvious reaction (the fish stiffens, colour fades, eyes dull). It is worth learning the iki point for the species you target; free online tools map it for fish around the world. Pair any dispatch with prompt bleeding and an ice slurry for the best result on the plate. Have a quick look at the current and most recent options on Amazon for the fish dispatch tools.

The IkiPik
The standout iki jime spike and a tackle-box favourite. It pairs a super-sharp 316 marine-grade stainless spike with a protective cover and a robust, high-visibility BPA-free grip handle, complete with a lanyard attachment and even a built-in bottle opener. It is bright and easy to find in the moment, comfortable to grip with cold, wet, slippery hands, and strong enough to penetrate everything from table fish up to large species like tuna and marlin. It fits neatly into boat and kayak rod holders so it is always to hand, and doubles as an ice pick. Simple, safe, and built to last a lifetime. Have a quick look at the current and most recent options on Amazon for the IkiPik fish spike.
Soulchen Ikejime Kit
The complete kit for full Japanese-style dispatch. It includes an iki jime spike plus a stainless shinkei jime wire, letting you both spike the brain and run the spine to delay rigor mortis and maximise flesh quality — the full method in one affordable package. Sized for medium fish like yellowtail, sea bass, and bream, it is an easy way for an angler to step up from a basic spike to proper iki jime and shinkei jime without buying pieces separately. Good value for anyone serious about eating quality. Have a quick look at the current and most recent options on Amazon for the Soulchen Ikejime Kit.
Wooden Donga Bat (Priest)
The traditional, foolproof option. A weighted hardwood club, the donga bat dispatches fish humanely with a firm knock to the head and doubles as a tool to stun a bigger fish that is thrashing on deck while you remove the hook. There is no point to keep covered, no technique to learn beyond a solid blow, and nothing to corrode — just a simple, reliable club with a lanyard. For anglers who want a no-fuss humane dispatch for a range of fish, or a backup to a spike, a quality priest is a timeless choice. Have a quick look at the current and most recent options on Amazon for the wooden fishing priest or donga bat.
Heavy-Duty Stainless Ice Pick Spike
The choice for big and tough fish. A long, sturdy stainless steel spike — often sold as a heavy ice pick with a safety cover and a solid wood or grippy handle — has the length and strength to reach and destroy the brain of large, powerful species that a short compact spike cannot. The safety cover protects the point and you, and the robust build shrugs off salt and hard use. For anglers chasing bigger table fish who want one strong, versatile spike that also breaks ice for the slurry, it is a practical pick. Have a quick look at the current and most recent options on Amazon for the heavy-duty stainless ice pick fish spike.
JYG Pro Ikejime Kit

It brings together the full set of tools — a stainless brain spike, a shinkei jime circuit-breaker wire, a dedicated bleeding knife, and a non-slip mat — for a clean, efficient, respectful process from dispatch to bleed. For anglers who treat fish prep seriously, chase tuna and other prime species, and want sashimi-grade results, having every purpose-built tool in one quality kit removes the guesswork. The most complete option here. Have a quick look at the current and most recent options on Amazon for the JYG Pro Ikejime Kit.

The Short Version
How you kill a fish you keep decides both how humanely it dies and how well it eats, so it is worth doing properly. Use a priest for a fast, simple knock when a spike is awkward, and an iki jime spike, sized to your fish and placed correctly, for the cleanest result. Bleed and chill the fish immediately afterwards, choose corrosion-proof tools that stay sharp and solid, and only ever dispatch fish you intend to keep, returning the rest quickly and gently to the water.
Pair it with the rest of a catch-care setup: our guides to the best fish fillet knives and boards, best fishing coolers and ice boxes, and the beginner fishing gear checklist round out the kit.
Common Questions
What is iki jime?
Iki jime is a method of killing a fish instantly by spiking the brain, which sits above and behind the eye. Done correctly the fish dies at once, without the prolonged stress of suffocating, and the flesh stays firmer and keeps longer because far less lactic acid builds up. It is widely regarded as the most humane way to dispatch a fish for the table, and it takes a little practice to place the spike accurately on each species.
Do I need a spike or a priest?
Either can dispatch a fish humanely, and many anglers carry both. A priest is simpler and more forgiving, delivering a firm knock to the head with no anatomy to locate, which suits a thrashing fish or a busy deck. A spike gives the cleanest, most instant result and the best meat, but you need to know where the brain sits on your target. Choose a priest for simplicity, a spike for the best outcome, or keep both.
Why bleed a fish after dispatching it?
Bleeding drains the blood that would otherwise sit in the flesh, taint the flavour and shorten how long the fish keeps. Immediately after dispatch, cut or tear the gills and let the fish bleed out, ideally in cold water or on ice. Combined with a quick kill, prompt bleeding and chilling makes a noticeable difference to how firm, clean and long-lasting the fillets are, which is the whole reason for dispatching the fish well in the first place.
