08 December 2021. Reef fish, such as emperors, tropical snappers and rockcods, help keep numbers of crown-of-thorns starfish in check on the Great Barrier Reef, according to a new study from the Australian Institute of Marine Science.

Fish Predators Help Control CoralEating CrownofThorns Starfish on Great Barrier Reef

Coral reefs are under threat. Climate change is having a significant impact, and voracious crown-of-thorns starfish (COTS) are an ongoing major issue. They eat their way through coral and impact restoration efforts. COTS have phenomenal reproductive abilities. As with pest species like locusts that wreak havoc on crops, COTS numbers can explode.

CrownofThorns Starfish Facts

The Crown-of-thorns Starfish Control Program supports coral growth and recovery by effectively controlling the coral predator to ecologically sustainable levels. Crown-of-thorns starfish are a native coral predator on the Great Barrier Reef. In outbreak proportions, they have been responsible for causing equal, if not greater declines in coral.

Managing Crownofthorns starfish on the Great Barrier Reef CSIRO

Crown-of-thorns starfish (COTS) are a native coral predator. On an 'average' reef on the Great Barrier Reef it takes as few as 5-6 adult COTS per hectare to cause a decline in coral cover. But COTS outbreak densities are frequently much higher than this and result in massive reductions in coral cover. This puts added pressure on the reef in.

The study led by the Reef Authority in collaboration with research and delivery partners demonstrated up to a six-fold reduction in starfish numbers and a 44 per cent increase in coral cover across regions that received timely and sufficient control effort. While crown-of-thorns starfish are native to the Reef, outbreaks can cause broadscale coral loss and reef degradation, which are another.
