摘要

On coral reefs, hard corals (order Scleractinia) provide habitat for an extraordinary diversity of reef fishes, many of which have close associations with the coral. Coral can provide these fishes nesting sites, food and protection from predators. The fishes can also benefit the corals, through fish-derived services resulting from, for example, diurnal and nocturnal movements, foraging, and nutrient excretion. Here, we synthesize how coral-associated fishes (i.e., coral reef fishes that have prolonged or permanent dependency on live coral) positively contribute to the health and resilience of corals. We highlight how certain coral-associated fishes offer a variety of benefits to corals, including enhanced oxygenation, nutrient subsidies and recycling, sediment removal, and protection against predators and parasites. Our review highlights the critical role that some coral-associated fishes have in supporting reef function, and in some cases, conferring resilience.
