What is a light fish?

The white hairtail fish (Tachiuo) does look like a sword in appearance, so it seems that it should be classified as a light object, but it is actually a Shiromi (white fish). In the world of sushi restaurants, Hikamono refers to sushi ingredients that use Sujime (a marinating technique used to make fish bones edible) during preparation. In addition, some chefs classify Shima aji with silver skin as "light fish", and after removing the skin, they classify Shima aji as white fish.
