The Best Ikejime Tools for Better Tasting Fish

Ikejime: How To Kill Fish Quickly and Humanely

Ikejime is a humane way of killing fish that is said to result in less lactic acid build-up, making for fresher-tasting fish. The process involves puncturing the fish’s brain with a sharp object, which then effectively stuns the fish and prevents it from thrashing around and damaging its flesh.

To correctly do it, it’s important to use the best Ikejime tools you can get your hands on.

Learning how to Ike Jime a fish gets easier when practiced over time. But the kit sure helps make preparing fish easier, especially if you’re not a pro. 

Here’s a guide on the best Ike Jime kits you can use to prepare your catch.

Frequently Asked Questions

How do you perform Ike Jime?

Ike Jime is an art of humanely killing fish developed and practiced by the Japanese. You perform this by noting where the fish’s brain is and inserting your spike towards it, usually above the eye, and crush the brain.
When the jaw drops, you should cut the gills, the fish’s main artery, and its tail to drain its blood. Then, sever its spinal cord before putting the fish in an ice slurry to preserve its umami flavor and prevent it from rigor mortis.

What is Shinkei Jime?

Shinkei Jime, also known as “spinal cord compression,” is a method of killing fish by compressing the spinal cord. This is done by inserting a metal rod or other sharp object into the fish’s brain cavity, just behind the eyes.
This method is considered the most humane way to kill fish, as it is instant and causes no pain.

How kill a fish instantly?

While Ikejime is a humane way of killing fish, there are other ways to kill your catch instantly. For one, you can kill a trout by knocking its head on a hard surface like a rock or a ledge. Now you know how to shorten a trout’s suffering. You have to learn how to fillet a fish.
