Ike Jime 80cm | Fish Nerve Relaxing Tool Long Set

Ikejime (活け締め) or Ikijime (活き締め) is traditional Japanese method of killing fish to maintain the quality of its meat.

It involves the insertion of a spike quickly and directly into the hindbrain, usually located slightly behind and above the eye, thereby causing immediate brain death.

Destroying the brain and the spinal cord of the fish will prevent reflex action from happening; such muscle movements would otherwise consume adenosine triphosphate (ATP) in the muscle, and as a result produce lactic acid, making the fish sour.

Furthermore, the blood contained in the fish flesh retracts to the gut cavity, which produces a better coloured and flavoured fillet.

Ike Jime is considered to be the fastest and most humane method of killing fish.

Features:

Neural drawing wire:

• Shape-memory Rust-resistant wire made of Stainless steel: diameter 1.2 mm × length 800 mm
• The wire surface is jaggy for effective destruction. 
• Easy to hold and work grip 90 × 20 mm

Spike with handle:

• Stainless steel needle pipe 90 mm long (grip 70 × 72 mm)

Plastic tube for safe storage

Detailed Instructions

1. Stick the spike

Stick the spike into the brain between the eyes* and search for the nerve position. You will know if the stick hit the nerve since the fish will respond to it.

*Spiking point where the fish’s brain is will vary from species to species.

2. Insert the wire

Put the wire through the hole in the spike and penetrate the spinal cord straight on.

During this process the fish will convulse – insert the wire slowly so as not to miss the spinal cord.

You can also use the spike as a venting tool!

Grip handle has a small hole to store the long wire compactly coiled.

Put both the wire and grip handle into both ends of the attached plastic tube and let the wire go through the hollow in the spike. Coil up the wire and put it through the small hole on the grip handle as seen in the diagram.
