In a pioneering effort to enhance local fish stocks and alleviate fishing pressure, researchers from the University of Hawaiʻi at Mānoa released around 60 tagged juvenile ulua (giant trevally), or pāpio, into Maui’s Maʻalaea Harbour in February. This initiative, spearheaded by PhD student Spencer Davis, is part of a broader research project aimed at showcasing the potential of raising and releasing pāpio for stock enhancement, food production, and ecosystem restoration. The project benefits from the collaboration of the Hawaiʻi Institute of Marine Biology, Maui Ocean Centre, and Oceanic Institute, and actively involves the community through a raffle for fishermen who report recaptures. An earlier phase of the project saw the release of about 150 tagged pāpio around Oʻahu, achieving a 14% recapture rate and evidence of the fish quickly integrating into the fishery and migrating up to eight miles from their release sites.

Juvenile fish released to boost fish stocks. About 60 specially raised pāpio (juvenile ulua, or giant trevally) were tagged and released into Maui’s Maʻalaea Harbour by University of Hawaiʻi at Mānoa researchers in February. The scientists want to demonstrate that raising and releasing pāpio can offset fishing pressure and help rebalance the composition of the local reef fish populations. Putting more fish into the ocean also benefits communities by providing increased access to locally produced, sustainable seafood. “Due to the great partnership between Hawaiʻi Institute of Marine Biology (HIMB), Maui Ocean Centre and Oceanic Institute, we had a very successful tag and release of pāpio on Maui. These collaborations are critical to grow aquaculture within Hawaiʻi for stock enhancement, food production and ecosystem restoration,” said HIMB Associate Research Professor Erik Franklin. Each tag is labelled with a unique fish identification number and a note with instructions to call ...
