Canadian seafood exporters must possess a fish export license in order to properly export, process, or store fish for export from Canada. Â The US Lacey Act prohibits the taking, possession, transportation or sale of fish taken in violation of foreign law. Â One importer in Maine will now have to pay up to $1.25 Million in fines for improperly importing approximately $172,000 of sea urchin because the exporter did not have the proper license.
