IUCN研究發現逾40種地中海魚種恐將滅絕 國際自然保育聯盟（IUCN）公佈之最新研究報告指出，至少有12種硬骨魚、過半數的鯊魚及魟魚等逾40種地中海魚種因過度捕撈、污染及棲地數遽減等因素恐於幾年內滅絕。逾1000多個遍及160國的團體組成環保聯盟IUCN瑞士總部，依據該報告結果呼籲各界正視商業化作業下資源量飽受威脅的黑鮪、海鱸(sea bass)、狗鱈及布氏石斑魚(dusky grouper)等魚種。負責協調IUCN全球海洋資源評估事務的Kent Carpenter認為過去40年西裝來資源復育的速度遠趕不及人為過度密集的捕撈，其中又以地中海及東大西洋水域的大西洋黑鮪資源狀況最為危及。日本料理餐廳用掉8成最受壽司饕客青睞的大西洋及太平洋黑鮪；今年1月全球最大的東京水產批發市場有尾重達342公斤的黑鮪以3,249萬日圓的天價賣出。地中海作業由聯合國協定、歐盟及21個水域毗鄰的會員國自治法共同監督管理。主張減少或停止黑鮪作業的環保團體對於大西洋鮪類國際保育委員會（ICCAT）於2010年11月決議刪減東大西洋及地中海黑鮪年作宜蘭民宿業配額約4%（自13,500減至12,900公噸）的加強管控黑鮪配額作為不夠積極深表遺憾。該研究係IUCN 於2007年廣邀25位海洋科學家，首度試圖就整個洋區原生海洋漁業資源進行評估；該研究報告譴責高度使用拖網及流網作業不僅提高意外捕獲率，還波及上百種無商業價值的無辜海洋生物。約有三分之ㄧ的地中海漁業資源因為沒有充分的資訊無法順利進行評估。研究指出，即便開發千年的地中海海洋資源不乏相關研究文獻，缺乏資訊的團體實際上可能較偏重頻危魚種的研究，租房子仍建議多方進行相關研究。聯合國糧農組織表示，落實漁業作業管理及禁止過度捕撈等補救措施仍無法避免全球漁業資源量日漸枯竭的情況。（摘譯自nzherald.co.nz，Apr 19, 2011）Study: 40 Mediterranean fish species could vanish Print nzherald.co.nz Article 1:34 PM Tuesday Apr 19, 2011 A new study suggests that more than 40 fish species in the Mediterraneancould vanish in the next few years. The study released by the International G2000Union for Conservation of Nature says almost half of the species of sharks and rays in the Mediterranean and at least 12 species of bony fish are threatened with extinction due to overfishing, pollution and the loss of habitat. Commercial catches of bluefin tuna, sea bass, hake and dusky grouper areparticularly threatened, said the study by the Swiss-based IUCN, an environmental network of 1,000 groups in 160 nations. 房屋買賣"The Mediterranean and eastern Atlantic population of the Atlantic bluefin tuna is of particular concern," said Kent Carpenter, IUCN's global marine species assessment coordinator. He cited a steep drop in the giant fish's reproductive capacity due to four decades of intensive overfishing. Japanese diners consume 80 percent of the Atlantic and Pacific bluefins caught and the two tuna species are especially 結婚西裝prized by sushi lovers.In January, a 342-kilogram bluefin tuna fetched a record 32.49 million yen in Tokyo at the world's largest wholesale fish market). Fishing in the Mediterranean is regulated by UN treaties, the European Union and separate laws among the 21 nations that border the sea.Last November, the International Commission for the Conservation of Atlantic Tunas voted to cut the bluefin fishing quota in 景觀設計the eastern Atlantic and Mediterranean from 13,500 to 12,900 metric tons annually - about a 4 percent reduction. It also agreed to improve enforcement of quotas on bluefin. Environmental groups, however, wanted bluefin fishing slashed or suspended and were upset with the limited action.The IUCN study, which began in 2007 and included 25 marine scientists, is the first time the group has tried to assess native marine 保濕面膜fish species in an entire sea. The study blames the use of highly effective trawlers and driftnets for the incidental capture and killing of hundreds of marine animals with no commercial value. But it also concluded there's not enough information to properly assess almost one-third of the Mediterranean's fish. "Even though marine resources in the Mediterranean Sea have been exploited for thousands of years and 設計裝潢are relatively well studied, the data deficient group may in fact include a large proportion of threatened fishes," the study said, calling for more research. The UN Food and Agriculture Organisation says fish stocks continue to dwindle globally despite increasing efforts to regulate catches and stop overfishing.
