The underlying mechanism that links fatty acids to coral health involves their role in the formation of cell membranes and energy production. Fatty acids influence membrane fluidity and function, which are essential for cellular signaling and metabolic processes. Furthermore, these fatty acids enhance the symbiotic relationship between corals and their endosymbiotic algae, known as zooxanthellae, by providing necessary nutrients that support photosynthesis and energy transfer. This relationship is crucial for coral resilience, especially under conditions of environmental stress such as rising sea temperatures and ocean acidification.

Additionally, the presence of specific fatty acids can bolster the immune response of corals, aiding in their defense against pathogens. Research in “Coral Reefs” has shown that fatty acid profiles of zooplankton vary, and feeding corals with zooplankton rich in essential fatty acids correlates with improved health and growth rates in coral species. This emphasizes the importance of selecting the best zooplankton for feeding coral to ensure they receive adequate nutritional support for their survival and long-term success.
