By the species? Meaning there are literally thousands of separate permits?Sure there is. Each country that ships CITES to the US, has an origination that issues the permit authorizes the shipment. Without it, you can not ship CITES animals into a CITES member nation. Without it, you cannot ship any livestock into the US. Pretty much every country has some sort of Bureau/Dept of Fisheries.
have you ever imported or exported marine livestock? It really doesn't sound like it... FWIW I have, and even worked with a village to help with their export docs to the states. All our permits had quotes per species, issued at both the federal and local level.
No, I am actually quite against wild collection in most cases, lol. ;-)
