Will Marine Reserve Protect Coral Sea Sharks?

Shark fishing needs to be banned at Osprey and Shark Reef in the Coral Sea for a Marine Reserve to work, concludes a study published yesterday. It is estimated that each year, live-aboard dive boats are directly responsible for generating at least AU$16 M worth of income. Of all the Coral Sea reef systems, Osprey Reef has the highest visitation rate by tourism operators, primarily to conduct shark dives. So, the depletion of reef sharks at Osprey Reef would have serious financial ramifications for the area. To put this into perspective, in the Maldives, the removal of only 20 grey reef sharks, with a market value of only AU$1 000, caused an estimated loss of AU$500 000 annually in diving revenue.

At 9 foot long, not including the tail, tiger shark (Galeocerdo cuvier) Harry Lindo is not exactly on the small side. In just over 3 years Harry swam over 44,000 kilometres – that’s more than the circumference of the Earth (just over 40,000 kilometres). Harry’s track is the longest recorded for a tiger shark, and probably the longest ever published for any shark species.
