Applying intensive copepod production technology to establish marine hatchery production in Palau The small island nation of Palau recently made a big impact across the Pacific region with a complete ban on commercial fishing in its EEZ. The ban was enacted to address environmental concerns related primarily to overharvesting and climate change, and Palau is now embracing aquaculture to help achieve its goals for national food security and a sustainable economy. In an effort to increase local aquaculture production capacity, researchers at Palau Community College Cooperative Research & Extension (PCC CRE) together with support from partners including the Center for Tropical and Subtropical Aquaculture (CTSA) and the Oceanic Institute of Hawaii Pacific University (OI) have spent the last decade establishing hatchery production of several regionally important species. At the PCC multi-species hatchery in the seaside village of Ngeremlengui, technicians currently produce

rabbitfish, milkfish, mangrove crabs, and coral grouper seedstock and fingerlings for local farmers. An important factor in the larval rearing success they have experienced thus far is the handson training they continue to receive in essential hatchery technologies, such as microalgae and copepod production. In 2013 under the

auspices of the CTSA-funded project “Broodstock Management, Seed Production and Grow-out of Rabbitfish, Siganus lineatus (Valenciennes, 1835) in Palau,� Dr. Chatham Callan, Director of the OI Finfish Department, conducted the first training at PCC to produce copepods as an alternative live feed organism in a rabbitfish larval
