Description: Raising fish and creating the optimal breeding and living environment is one of the biggest challenges to restoring loko iʻa (Hawaiian fishponds). Pre-western contact, loko iʻa were a key part of the Hawaiian food production system for hundreds of years. Today’s environmental conditions require modern technology to raise juvenile fish (pua) and limu (macroalgae) to assist in loko iʻa restoration efforts. Pua Boot Camp aims to develop an integrated system at Waikalua Aquatic Institute that will serve as a nursery for juvenile fish and the cultivation of limu necessary to filter and manage nutrients to keep the pond in a livable state. The nursery comprises a flow-through system through which saltwater from the loko iʻa flows through a tumble culture limu tank, before returning to the loko iʻa. The ultimate goal is to raise fish in the tanks until they are a viable size for release into loko iʻa and to outplant limu. This presentation will examine early trial data on optimal conditions for limu cultivation including light intensity, nutrients, and overall maintenance and husbandry of the facility; and will solicit industry expertise and feedback to advance this work. Please join us to contribute your knowledge and learn about this important research.
Presenter: Seaenna Correa-Garcia, is a masters student at UH Mānoa working with Dr. Kai Fox at Waikalua Aquatic Institute. Seaenna was born and raised within Koʻolaupoko and received her bachelor’s degree in Marine Science with a minor in Environmental Science at California State University, Monteray Bay. Seanna’s research focuses on cultivating native limu within land-based tank culture systems.
