Some wholesale distributers use
http://www.reefcheck.org/
A group of folks dedicated to saving the oceans and reefs.
Many boxes i have unpacked contain this sticker saying verified by reefcheck.
These folks check and verify the contents of the packages to ensure that no red listed or poor packaging practices are used.
There is also cities who controls how many and what species are exported from a country, we here in the western world know them as the folks that wont allow us to import, but they also stop countries from exporting.
And each country has there own "wild life police" These are the ones that restrict collection in certain protected areas and some reefs.
Remember when Bush Jr left the presidents office he set aside 195000 square miles in the Pacific Ocean.
There are some protections in place already, what they are doing in Hawaii is only a new step in protecting the oceans.
Outrage over Hawaii closing ornamental fishing is bound to happen, but really they have tried many other methods already and are still failing.
