The Black Fish news release:

"On Sunday a diving team of The Black Fish successfully released hundreds of bluefin tuna back into the Adriatic Sea from cages at a fish farm near the island of Ugljan, Croatia. The action is marking the start of a new campaign to highlight the lucrative trade in the endangered bluefin tuna, a fish species heavily impacted by illegal overfishing in the Mediterranean Sea. The Black Fish have been working on the ground in Croatia for several weeks investigating the country's controversial tuna industry. It was three days ago when our crew members witnessed the slaughter of several tuna fish and decided to intervene. Members of our diving team were able to pass by security and entered the water late at night to free the fish." Click here to read more.
