Like I said, those were just WAGs based on "current" Canadian prices. This would work the same way that it works in Canada for the most part, so that's my model for now.
The prices may (most likely will) be higher. When they started importing in Canada, the greens were $1250.
Don't know how many follow this stuff, but the prices in Asia have been dropping A LOT lately. There are more farms producing, and less interest in them.
I really didn't want to turn this into a debate about prices. They will vary by hundreds of dollars from reality. IMO, if you're serious about them and really want the fish, paying a few hundred over the prices I listed shouldn't be a problem.
As for the risk of causing wild harvesting by allowing US imports. They will still need to be chipped and declared when entering the country. If a shipment comes in without a CITES permit, an ESA permit and microchips in the fish, you're still going to get nailed for illegally importing an endangered species.
