Striped jack (Shima aji)

What is Shimaaji?
Wild ones that are caught during summer are wonderfully fine-textured with high-quality fat. A fish that weigh about 1-2 kg is considered best. Unfortunately natural ones are no longer available; 99% of them are farmed ones. Therefore, while most of the sushi presented as Striped jack at conveyor belt sushi restaurants is naturally caught fish from New Zealand, it is actually a subspecies of Striped jack. It doesn’t have fat and lacks in flavor.

Trivia 1 : For hikari-mono nigiri (silver-skinned fish), a bit of the silver skin is left on the back of the Striped jack, and when the skin is completely removed, it becomes a white-meat sushi topping.

Trivia 2 : There are a lot of farmed fish at the market, but of course they don't taste as good as the natural ones. However, there is only a small amount of natural striped jack and they cost five more times of the farmed ones.
