Aquaculture and early life stages of the Hawaiian Potter's angelfish (Centropyge potteri)
This study provides the first successful, replicated aquaculture methods for the Hawaiian endemic Potter’s angelfish (Centropyge potteri), once heavily collected for the aquarium trade. By refining larval feeding protocols and rearing conditions, survival to settlement improved from 0% to 3.4%. Results highlight the importance of feed timing, live algae and copepods, and stable environments for success. These findings lay the groundwork for sustainable aquaculture of Potter’s angelfish and other high-value reef fishes, reducing pressure on wild populations and supporting reef conservation.

How Environmental Policy Shapes the Aquarium Trade: Aquaculture of the Hawaiian Endemic Potter's Angelfish (Centropyge potteri)
This project explores the aquaculture of the Hawaiian endemic Potter’s angelfish (Centropyge potteri), once a major export in Hawaii’s aquarium trade before collection was banned. By testing larval feeding regimes and monitoring growth and survival, the research advances knowledge of captive breeding for this iconic species. At the same time, it examines how Hawai‘i’s environmental policies shape the sustainability of the aquarium trade, drawing on policy analysis and stakeholder perspectives. Together, these findings inform future conservation, aquaculture practices, and sustainable management of reef fishes.
