Ike Jime (spinal cord destruction) fish killing
I learnt recently that the Japanese kill fishes by
1. cut spine and vessels at the head. 2. cut spine at the tail 3. run a wire down the length of the fish at the spine to paralyze the fish. 4. bleed fish in ice water The theory is that the spine destruction stops the nerve sending signals to the muscle and fish meat stays fresh longer. This technique is confirmed by some objective scientific tests. Search for Ike Jime, you'll find a lot of videos and test results. The best link I found about this topic is here. http://cookingissues.wordpress.com/2...w-to-pointers/ Does anyone practice this for their game fish? |

lactate released by the fish at the time it has been fighting makes the meat go bad... pics taken off the Canada coast...

Re: Ike Jime (spinal cord destruction) fish killing
I've heard thats the way to go (spining) for quality fish, especially BF, interesting that the use piano wire, makes sense.

Re: Ike Jime (spinal cord destruction) fish killing
It is the taniguchi method! but it is worthless if done after the tunas head is removed! as soon as the fish is brought aboard you want to cut a notch in its head at the base of the spine to be able to gain access to run a cable through the leangth of the spine to kill it quickly and stop the build up of acide and reduce stress on the fish.

Re: Ike Jime (spinal cord destruction) fish killing
i have found that tie wire works best. It is a bit stiffer than piano wire and smooth - you can pick some up at any construction/ builders store (whitecap). very cheap stuff. I just cut length needed and wipe off all of the residue using a cloth and salt water. (tie wire is the stuff we use for tying steel re-bar together before pouring concrete)

Re: Ike Jime (spinal cord destruction) fish killing
Teleflex cable is what we have always used on longline boats! just crimp a loop in one end and grind the other end with a rounded point and it works better than most plus its stainless

Re: Ike Jime (spinal cord destruction) fish killing
It is primarily used to kill the fish instantly thus not allowing the buildup of acid in the meat.If the fish beats around the deck while trying to remove the head it kind of defeats the purpose of bruising the meat and causing stress to the fish! All the comm boats ive ever worked on running the wire was the first order of business before anything else

Re: Ike Jime (spinal cord destruction) fish killing
I have heard about doing this for snapping turtles but never for fish.

Re: Ike Jime (spinal cord destruction) fish killing
They say that is true with hunting big game animals. If you shoot a deer with a bow the adrenaline runs through the meat. But if you drill a deer with a rifle the adrenaline does not go through the meat therefore tasting better. I shoot berger bullets so I never have an issue with animals running.
