Jacks and barracuda in Heʻeia fishpond were found to feed on Australian mullet, an invasive species introduced to Oahu waters in the 1950s. This finding, published in Aquaculture, Fish, and Fisheries by researchers from the University of Hawaiʻi at Mānoa, University of California at Santa Barbara (UCSB), and Paepae O Heʻeia suggests that these native predatory fish may provide a form of biocontrol on populations of the invasive mullet species.
