My State Biologist buddy says 2004 for the NOAA report.
I spent a great deal of time going through this site below, I was amazed. More information and free than you can imagine and the interesting part is they are not ashamed one bit to show you the numbers and what they plan to do!! I was mostly looking for more information on the foreign influence on the resource as I know what the Asian commercials do that does not get counted. Once I finish gathering more info in my next couple trips to Asia, I will let you know.
