WAILUKU >> A Maui research and conservation group says 10 percent of the more than 300 manta rays in waters south of Lahaina have amputated or severely damaged fins.

The Hawaii Association for Marine Education and Research says the manta rays are injured when they get caught in fishing lines.

The Maui News reports the Lahaina-based nonprofit is trying to raise money to buy acoustic and satellite tags to track manta rays and create a protection plan.

The tags will provide information on feeding grounds and pupping areas. This will help researchers determine where the fish are getting entangled.

Olowalu south of Lahaina is one of a few places in the world where manta rays are known to gather. The only other place in the state is off Kona.
