These tiny wader birds have flown from Russia, and traditionally would have found bountiful food here, at South Australia's Coorong wetlands. But the river isn't delivering enough fresh water into the Coorong, so saline levels are rising, killing many fish. Trawling the South Lagoon, researchers David Short and Neil Wellman have found only one species of fish. In past years, a sweep would yield hundreds.
这些娇小涉水的鸟从俄罗斯飞来,以前都会在这里南澳洲的库隆湿地,找到充足的食物,但河没有为库隆带来充足新鲜的水,所以盐分在增加、害死了许多鱼,在南潟湖拖网捕鱼,研究员大卫秀特和尼尔魏尔曼只发现了一种鱼,以前随便捞就有上百种!

The results suggest that policy simulation aimed to maximize the economic will increasing all fishing effort of all fishing sector except demersal trawl should be reduced 43.2%, and social strategy were suggested increasing small-scale fishing effort to satisfy social benefits, especially for miscellaneous will increase 3.48 times on current level, maximize ecological suggested all fishing sector should be reduced drastically or stop.
结果表明:以经济利益最大化为管理策略时会提高所有渔具的捕捞努力量,除了拖网下降43.2%之外;以社会利益最大化为管理策略时模型要求极大地增加小型渔业,尤其是混合渔业的捕捞努力量将上升3.34倍;而以生态稳定性最大化为管理目标时,模型要求所有渔业的捕捞努力量都必须降低甚至停止。
