Description
Ángela Randazzo-Eisemann and colleagues surveyed parrotfish roles on a remote reef in 2024. Caribbean reefs are shifting from coral to seaweed cover. Parrotfish are famed as the reef's main grazers. They also erode reef structure as they feed. Treating all parrotfish as one group hides species differences. The team tested whether fish roles track local habitat. Surveys covered the wide Alacranes Reef in the Gulf of Mexico. It is the largest reef system there. Fish counts and bottom cover were recorded together.
Erosion and grazing potential peaked at complex, structured sites. Seaweed removal also ran high at deep, low-coral sites. Shallow inner reefs told a poorer story. Turf algae and cyanobacteria dominated those areas. Both fish functions faded badly there. Even grazing failed under poor bottom conditions. The authors urge species-specific fish management. Bottom state and fish roles shape each other, they argue.
