The Government of the Nauru issued the ban on transshipping in its waters outside its port, and is calling on other Pacific Island Nations to do the same. A regular industry practice that is largely unmonitored, transshipping involves fishing vessels - longliners - transferring their catch to ‘motherships’ to be taken and sold in far-away markets. This means that boats can stay out at sea for years, evading checks on their fishing practices and licenses, and the treatment of their crew.
