Warming seas wreak havoc on reef fish

Fish species on the Great Barrier Reef are starving to death because climate change is killing off their food source, an environmental study has found.

Rising sea temperatures have bleached more than 30 per cent of the world's coral reefs, a five-year study by the ARC Centre of Excellence for Coral Reef Studies (CoECRS) has found.

As a result, smaller fish which would normally feed on live coral are dying off, which could throw the fish food chain out of balance, and consequently hinder local fishing and tourism operations.

The coral damage is predicted to double by 2030 if sea temperatures continue their warming patterns, CoECRS senior researcher Morgan Pratchett said.
