A study by the Australian Marine Institute found that Palau’s shark-diving industry is worth far more than its shark-fishing industry. A single reef shark that frequents major dive sites in Palau is worth roughly $179,000 annually, or $1.9 million over its lifetime; the same shark would be worth about $108 dead.
敦促各国采取护鲨行动应该并非难事，因为鲨鱼一旦被杀其经济价值就大幅降低。澳大利亚海洋研究所的一项研究发现帕劳鲨鱼潜水业的价值远非鲨鱼捕捞业可比。一头经常出没于帕劳各大潜水点的礁鲨年价值约合179,000美元，终生价值约合190万美元；而同一头鲨鱼如果被杀死只值约108美元。
