This time Kim Holland, director of the shark lab, suggested a more judicious approach: first figure out how the sharks actually behave. If they keep to a small territory, a locally targeted eradication program could reduce the danger. But if they have no territorial allegiance, an aggressive animal might kill and disappear, never to return, and slaughtering the sharks that remained might not help...
With funding from the federal Sea Grant Program and help from students, including Lowe and Meyer, Holland began hooking tiger sharks off Waikiki Beach. Smaller specimens get old-fashioned tags; if a tagged shark is recaptured, the scientists know that it has returned to the same spot at least once...
...least 10 ft. long get a 6-in.-long cylindrical beeper deposited inside an incision in the belly. Every time the shark nears an acoustic receiver anchored on the ocean floor, it leaves a record of its visit. Based both on these records and on open-ocean shark chases, Holland has come to several conclusions. "First," he says, "we've established that tiger sharks do have home ranges." Those ranges, however, are huge: Holland's crew has tracked sharks all the way to Molokai, 25 miles away...
Moreover, the sharks patrol these ranges randomly. They may return to a given spot twice in one week, then not again for months. "It's clear," says Holland, "that you can't significantly reduce the local shark population by fishing for a limited time in a single area. You'd have to reduce the general population to have any effect--and that's not acceptable anymore...
WHAT KILLED THE BOOM To protect its merchant fleet, Holland built an armada larger than the British and French navies combined. But the cost of this outsize national defense caused taxes to rise sharply, and the Netherlands still lost its naval supremacy. The result was the end of Dutch mastery...
