Local Fish can't get more fresh
I have the luxury here on Maui, to buy my fish from the fisherman rather than from a large company. We have many licensed fisherman come to the kitchen, often at odd hours, with fish they caught only hours before. Most of the time they come straight from the water to the restaurant, eliminating the middle man and the time it may sit in the fish companies refrigeration. In the islands we get some of the freshest fish in the world, that on the mainland has to be shipped overnight, then distributed to the fish companies, before being fileted then sold. My point is, the fish I'm getting is as fresh as you're going to find.
