美国专家因鲤鱼泛滥求助中国:想吃多少就吃多少(图)

2014-09-30 07:25:31   新京报

新京报:可能对中国读者来说,第一个想到解决亚洲鲤的办法是“吃掉它”。

Jim:中国人很喜欢吃鲤鱼,在美国和加拿大一些民族市场也可以买到鲤鱼。实际上,我所在的南伊利诺伊大学,就曾经促销这些野生鱼类来帮助它们进入市场。鲤鱼促进了部分美国市场的经济发展,例如鱼肉的生产、鱼类市场的销售和有机肥料等。

新京报:但听说这些鱼类在美国并没有市场?

Jim:尽管科学研究表明鱼是消费者获得蛋白质最健康的来源,但实际上美国人吃鸡肉、猪肉或牛肉,却很少吃鱼肉。中国人很有品位,也十分了解鱼的营养价值,在这方面,美国的消费者应该多学习了解。

新京报:在美国,亚洲鲤就没有别的用途了吗?

Jim:你可能不相信,美国有一个小的旅游项目,专门让游客用弓和箭去射跳到水面上的银鲤鱼(白鲢),那里会有钓鱼导游把游客带到河里,去捕跳出水面的鱼。

新京报:中国网友戏称如果美国政府出资支付让他们去美国吃鱼,鲤鱼困境会大大缓解,还能带动当地其他消费。你怎么看这样的建议?

Jim:中式的鱼头汤是我最喜欢吃的食物之一,所以我理解中国人想来美国享用这道美味的想法。非常欢迎中国人来美国旅游,参观我们的湖泊,想吃多少鱼就吃多少鱼,但是美国政府不会为游客们买单。

新京报:能为我们说说亚洲鲤在美国的情况吗?它最早是如何进入美国的?

Jim:亚洲鲤在美国的情况很复杂。最早进入美国的是一种在欧洲和亚洲很常见的鲤鱼(吃昆虫为生),在19世纪被引进。1963年,草鱼(另一种吃水生植物的鱼)被带入美国,成功控制了水生植物的疯长。19世纪70年代,吃水螺和蚌类的黑鲤鱼,以及胖头鱼和银鲤鱼被带入美国。它们都很好地存活下来了。

新京报:当地政府和民众在最初发现时的态度是怎样的?

Jim:鲤鱼大概被引入美国30年后,当它们流入伊利诺伊河时,美国民众才意识到亚洲鲤的存在。直到我们发现鲤鱼威胁着五大湖区域--具有重要经济价值的生态系统时,民众才意识到问题的严重性,并要求政府采取手段治理。亚洲鲤的数量在伊利诺伊河中已经十分密集了,美国本土及国际媒体也有大量的报道。

新京报:亚洲鲤可能对美国生态造成的最大威胁是什么?
