The ike jime spike is not new to New Zealand, it offers an instant and humane way of killing live fish. As far as I know, the shinkei jime is previously not available in New Zealand. The shinkei jime takes the concept of ike jime further as it has a stainless steel cable that feeds through the spike into the spinal cord of the fish and severe the spinal cord.

This stops nerves contractions in the body of the fish, the muscles relax and blood does not go down into the meat.

Shinkei jime together with deep chilling in an ice slurry and proper bleeding of the fish.

Will optimises the eating quality and starts the creation of umami flavour in the flesh.

If you eat the fish raw or cooked both ways will benefit from this method of preservation.
