How Long is Fresh Fish Fresh

[Jimbo]

Just had a discussion with the chef here. He had a fish fest going for lunch in our cafeteria with salmon, haddock, grouper, and ironically, bluefish, all of which had the word "fresh" in front of it. So I axed him, "Is it really fresh? I always heard 60 minutes from the shore and it ain't fresh fish anymore." I could even go so far as to say it might be considered fresh if it was eaten within 24 hours of being caught. He had no idea where it all even came from originally, nor that it was flash frozen fresh.
So Cheferson, RickB, or anyone else out there know what constitutes fresh fish? And where are they catching bluefish this time of year in such identical, tiny, little filets?
