Effects of Asparagopsis taxiformis metabolites on the feeding behaviour of post-larval Acanthurus triostegus.

Our study highlights the effect of the macroalgae Asparagopsis taxiformis on the feeding behaviour of the tropical surgeonfish Acanthurus triostegus. The presence of A. taxiformis chemical cues reduced A. triostegus feeding, suggesting that the presence of this algae could affect not only the survival of fish in the post-larval stage, but also alter the grazing pressure on coral reefs.
