Interesting article. Something like 80% of the sea food sold in America is imported from Asia. Why not cut out the importer and just eat the asian fish coming straight from American waters. If we're stuck with them, might as well utilize them.
Funny thing is for as much seafood as we import, the dogfish caught off the US East coast in large numbers , until recently , have been exported to Asia. They love em', we don't. Although recent efforts by a few US epicures have resulted in a growing US market for dog fish.
