Plant-grazing fish boost resilience of coral reefs facing stress

By using cages to experimentally control the access of fish to coral reefs, researchers have assessed the role of fish "grazing" in the ability of reefs to successfully recover from potentially devastating coral-bleaching events related to rises in ocean temperatures. The findings, reported by a group led by Terry Hughes of James Cook University in Australia, will appear in Current Biology online on February 8th.

Pollution and overfishing have for some time been major threats to the health of coral-reef ecosystems, but additional environmental stress caused by warming of ocean waters has recently become a key factor in coral-reef stability. The importance of this kind of stress is illustrated by the massive coral-bleaching event of 19971998, which impacted 16% of the world's reefs and was particularly damaging in regions of the Pacific and Indian Oceans.

In the new work, the Australian researchers took an innovative approach to studying the recovery of coral reefs after the 19971998 event. Instead of simply observing and describing effects of the event and subsequent trajectories of reef health, the authors of the study experimentally tested the ability of reefs to recover under two different conditions: the presence of abundant predatory and herbivorous (plant- and algae-eating) fish, and the absence of significant numbers of these fish. The latter condition, which was achieved by placing large cages over coral reef stands to keep large fish away, mimicked the conditions under which coral reefs would recover from a bleaching event in areas also experiencing chronic overfishing.

The experiment assessed coral recovery in a region of the Great Barrier Reef Marine Park that is strictly protected from fishing, such that only coral stands under experimental cages experienced the depletion of large predatory and herbivorous fish. The researchers found that the two groups of coral underwent very different courses of recovery from the bleach
