我们对珊瑚礁渔业,特别是活礁鱼食品贸易(FT)的生态足迹的分析表明,许多国家目前的消费量超过了估计的可持续的人均全球、地区及地方珊瑚礁生产水平。香港通过其FT需求占有了东南亚年礁鱼生产量135260～286560t的25%,超过地区生物生产力8.3倍;礁鱼渔业需求超过印度洋-太平洋和东南亚地区可持续产量2.5～6倍。相比之下,大多数太平洋岛屿靠本身的礁渔业手段维持生计,当地的需求小于大洋洲整个能力的20%。FT每年需要多达40%东南亚的估计礁鱼产量以及几乎所有其估计的鮨科鱼产量。我们的研究分析结果强调了FT的不可持续性以及对印度洋-太平洋珊瑚礁渔业加以区域管理和保护的迫切必要性。
Our analysis of the ecological footprint of coral reef fisheries, in particular the reef food trade (FT), shows that current consumption in many countries exceeds the estimated sustainable global, regional and local reef production per capita. Hong Kong, through its FT demand, accounts for 25% of annual reef fish production in the region of 135260-286560t in Southeast Asia, more than 8.3 times the biological productivity of the region. The reef fishing industry needs more than 2.5-6 times of the sustainable production in the Indian Ocean, Pacific and Southeast Asia. In contrast, most Pacific islands depend on their own reef fisheries for subsistence, with local demand being less than 20% of Oceania’s total capacity. FT requires up to 40% of estimated reef production in Southeast Asia and almost all of its estimated sluggish fish production per year. Our research analysis highlights the unsustainability of FT and the urgent need for regional management and protection of Indian Ocean-Pacific coral reef fisheries.
