Tracking of endangered hammerhead sharks in Cocos Island
Help Turtle Island Restoration Network researchers continue critical migratory tagging and tracking of endangered hammerhead sharks.
Our oceans are in imminent danger. Industrial fishing is indiscriminately killing sharks, sea turtles and whales – threatened and endangered species that become collateral damage. Even in the biodiverse hotspot of the Cocos Island National Marine Park in Costa Rica, these highly migratory sharks are threatened by intense fishing activity once they leave the protected waters of the reserve.
To help put an end to the dramatic population declines, Turtle Island Restoration Network studies and works to conserve endangered scalloped hammerhead and other shark species at Cocos Island. Outside park boundaries, sharks face a gauntlet of industrial fishing vessels and are frequently seen trailing hooks and line from their mouths due to interactions with longline fishing operations. Even inside park boundaries, rangers report seeing vessels illegally fishing at night.
With your support, Turtle Island Restoration Network will carry out research that documents shark migration outside the Cocos Island National Park boundaries and their vulnerability to industrial fishing – developing the scientific basis to establish protections for the last great hammerhead shark schools. We will tag approximately 24 hammerhead, silky, tiger and other shark species with acoustical tags over two years, track their migratory routes and publicize the results.
The acoustical tags will be crucial in establishing shark protection and conservation measures in the region.
