AN OFFSHORE farming project has just ended in Hawaii with 70,000 Pacific threadfin (Polydactus sexilifis - known locally as 'moi') harvested from a submersible cage moored two miles off Ewa Beach, Ohau.
The harvest was the culmination of a trial conducted by the Sea Grant Program at the University of Hawaii, known as the Hawaii Offshore Research Project (HOARP).
A SeaStation cage developed by Ocean Spar Technologies (OST), USA was used in the project, and was submerged 12 metres below the surface for all of the seven months it took to grow the fish to market size.
