Divers chained the propellers of four vessels with a history of pirate fishing to the quayside in the port of Aviero (Portugal). Greenpeace will hand over the keys to the lock chaining the vessels Red, Caribe, Brites and Aveirense to the dockside to the port authorities of Aveiro. The vessels are owned by Grupo Silva Vieira, and all have track records of involvement in pirate fishing including fishing without a flag or legal quota, using illegal gear, using multiple identities, and other breaches of international regulations.
