The Sea Shepherd Galapagos Patrol vessel Sirenian carrying Galapagos National Park Rangers and Ecuadorian Naval crew intercepted and arrested the Adonai V, some 30 miles to the Southeast of Floreana Island on March 19, 2003.
Also arrested were two tender vessels the Moon Sea and Always Carmita.
After boarding the boats, the rangers identified some 75 illegally taken sharks.
The Adonai V was escorted to San Cristobal Island where it will be guarded by the Sirenian to prevent escape pending a court hearing.
On March 17 on the Island of Isabela, National Park Rangers and Naval officers stopped a truck and found 4,147 shark parts estimated to have been taken from 850 illegally caught sharks. The truck has been seized and the driver has been arrested and is awaiting a court appearance.
