NEW ANALYSIS CONFIRMS SHARKS ARE IN TROUBLE

Sharks are in big trouble on the Great Barrier Reef and worldwide, according to an Australian-based team who have developed a world-first way to measure rates of decline in shark populations.

“There is mounting evidence of widespread, substantial, and ongoing declines in the abundance of shark populations worldwide, coincident with marked rises in global shark catches in the
last half-century,” say Mizue Hisano, Professor Sean Connolly and Dr William Robbins from the ARC Centre of Excellence for Coral Reef Studies and James Cook University.

“Overfishing of sharks is now recognized as a major global conservation concern, with increasing numbers of shark species added to the International Union for the Conservation of Nature’s list of threatened species,” they say in the latest issue of the international science journal PLos ONE

“Evaluating population trends for sharks is complicated,” explains Professor Connolly. “The simplest approach of looking at trends in fisheries catches doesn’t work well for sharks. First, many countries with coral reefs don’t keep reliable records of catches or fishing effort. Second, around 75 per cent of the world shark catch consists of illegal and unreported finning. Third, sharks may be caught, discarded, and not reported when fishers are targeting other species.”
