A shark sanctuary is an area that forbids commercial fishing operations from targeting and retaining caught sharks, including their fins. The first shark sanctuary was created by Palau in 2009. It was followed by Maldives, Honduras, The Bahamas and Tokelau. ==Background== Every year, fishermen pull "up to 73 million"〔 or "some 100 million" sharks from the world's oceans.〔 The United Nations Food and Agriculture Organization (FAO) estimates that more than half of shark species are overexploited or depleted.〔 〕 Globally, 21% of shark species whose extinction risk has been assessed fall into the "threatened" categories, and 18% are "near threatened", while 35% lack sufficient data to decide, leaving 26% in the unthreatened category. The search for shark fins drives the illegal hunting trade. Some jurisdictions permit fishing for fins and food. Sharks are also caught as bycatch when fishing for marlin, tuna and other varieties.〔 Sharks generally reach sexual maturity only after several years of life and produce very few offspring in comparison to other harvested fish. Harvesting sharks before they reproduce has severe impacts on future populations. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shark sanctuary」の詳細全文を読む スポンサード リンク
