Abstract
The Potter's angelfish (Centropyge potteri) is a striking reef fish endemic to the Hawaiian archipelago, highly sought after by aquarists for its vibrant colors and unique characteristics. This species was once one of the most exported aquarium fish from Hawaii before a ban on fish collection for the aquarium trade. This research project investigates the larval rearing and growth of captive bred Potter's angelfish within the context of Hawaii's role and history in the aquarium trade, while concurrently examining the influence of environmental policies on the trade's sustainability. The study employs an interdisciplinary approach, combining laboratory trials with policy scenarios aimed at promoting sustainability. Five larval feeding regimes were tested, aiming to enhance the survival rates and growth trajectories of Potter's angelfish larvae. Morphometric and survival data were collected to monitor developmental milestones and assess the survival rate of reared individuals. Simultaneously, the research addresses the broader implications of Hawaii's environmental policies on the aquarium trade. The effects of Hawaii’s aquarium ban were assessed with regard to supply, demand, and prices of previously heavily exported species, Yellow tang and Potter’s angelfish. Interviews with stakeholders provide valuable insights into the perspectives and experiences surrounding the implementation and enforcement of these policies. A proposed policy scenario is presented with impacts on stakeholders described. The project's outcomes aim to contribute essential data to the scientific understanding of Potter's angelfish larval biology and rearing requirements, thereby informing future larviculture research and potential conservation strategies for this iconic species. Additionally, the study assesses the role of environmental policies in shaping the sustainability of the aquarium trade in Hawaii, with implications for global marine conservation efforts. The integration of scientific findings and stakeholder perspectives ensures a holistic approach to addressing the complex interplay between the aquarium industry, marine ornamental aquaculture, and regulatory frameworks in Hawaii.
