There are 6 instances where species are listed as okay to eat if they are from the US while not okay to eat if they are from elsewhere. There are 0 instances where the opposite is true.
Yes, there is, due to a lot of the data being sourced from the Monterey Bay Aquarium, whose data is US-centric. If you look at the detail view of eg crayfish ( http://whichfish.org/detail/crayfish_us.html ), the issue is that the other sources have no data, so I had to use the likely overly US-centric view.
Which is a pretty big issue. Local sources matter. For example the King Crabs in the Barents Sea are really invasive and are spreading like wildfire. In Norway they are trying to hinder it's advancement and reducing it's population. Russia however, is currently more protective. After all they introduced them in the first place.
No, imho it's not bias. For wild fish, the US enforces the quantity of fish that can be taken much more effectively, than, say China/Japan.
Second, the regulations/practices on the environmental impact of fish farms on the nearby sea are probably better in the US than elsewhere (many fish farms are in the backwaters of an ocean).
Do you really find it hard to believe that the USA has higher standards of environmental protection than other countries?
A fish doesn't care what country it was caught by. The US limits are surely set with the current population in mind... a population that is directly effected by what other countries are fishing. The more Japanese fish you eat, the less America fishes. It all evens out.

# yes Barramundi (US/Europe/Australia) # yes Barramundi (Closed Production) # no Barramundi (Other)
# yes Catfish (US Farmed) # no Catfish (Other)
# yes Crayfish (US) # no Crayfish (Other)
# yes Herring (Norway, Iceland, North Sea, US) # no Herring (Other)
# yes King Crab (US) # no King Crab (Other)

There seems to be some bias towards US fisheries in this list.
