What the heck are you talking about? Their problem ISN'T that they have plenty of fish around and people aren't buying American fish, it's that the California commercial fishermen wiped out their own fishery and they can look in the mirror if they want to see the cause of their problems.
It's the Japanese buying fish from us,btw, not the other way around...the Japanese wiped out their own fishery before we destroyed ours, and their big money purchases are now helping us wipe out the last of our fish.
