文摘

Feeding preference trials were performed on a surgeonfish (Ctenochaetus striatus). Trials assessed preferences between fine vs. coarse and river vs. reef sediments. Fine sediments reduced feeding rates while sediment composition had no effect. Fine sediments prevent Ctenochaetus striatus from feeding selectively on detritus. Reduced feeding by Ctenochaetus striatus may lower coral reef resilience.
