Limu

Limu (general term for algae and seaweeds) is the base of the food web in loko iʻa systems. Our loko iʻa are non-intensive, meaning that fish are not fed from external sources and all energy requirements are met internally through primary production and the subsequent energy transfer into higher trophic levels. The fishponds at Kumuola are largely dominated by microalgae, providing a rich food source for healthy populations of herbivores like the ʻamaʻama (Mugil cephalus). We are early in our research into the limu dynamics that occur within the loko iʻa, but understand the importance of limu as the kahua (foundation) from which our loko iʻa thrive. Linked below is student research looking into primary production and consumption rates within the loko iʻa.
