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

亚洲鲤鱼突然跃出水面,对游客“发动袭击”。

在美国伊利诺伊河,可以见到这样的场面,成群的亚洲鲤跃出水面。

体重近30公斤的亚洲鲤跃出水面,这一中国长江上也难得的景观,在美国密西西比河却极为常见。

以青草鲢鳙“四大家鱼”为主的8种亚洲本土鱼类,在美国被统称为亚洲鲤鱼。它们在进入美国的部分水系后,生长迅速,甚至对当地生态造成巨大威胁。

9月9日至12日,美国亚洲鲤专家Jim Garvey和他的同伴们,受大自然保护协会(TNC)中国部之邀,组团来中国寻找解决亚洲鲤泛滥的方法。多年来,TNC一直致力解决长江生态及鱼类资源恢复和亚洲鲤问题。

他们参观了上海水产市场和武汉水产加工厂,也品尝了红烧鲤鱼和鳙鱼头泡饼,为在美国成灾的亚洲鲤寻找商业贸易的可能性。

中国TNC淡水项目专家杨波说,对于当前国内对亚洲鲤的热议,对推动亚洲鲤商业解决方案是个好兆头,但中美专家都希望在保障不造成新的生态问题的前提下寻求科学合理的商业解决方案。

新京报对话美国亚洲鲤专家Jim Garvey,请他来讲述亚洲鲤如何进入美国,以及他所在的国家如何与亚洲鲤“作战”。

吃不掉的亚洲鲤

新京报:美国专家来中国寻找解决亚洲鲤泛滥的方法,很多中国人会觉得听起来是有趣的事情。

Jim:我知道亚洲鲤对中国人来说是一种很重要的食物,我尊重你们(的饮食习惯),几千年来中国人一直依赖于这种营养且美味的食物资源。然而,亚洲鲤这些外来物种在美国的密西西比河及其支流泛滥,我们担心这些鲤鱼会减少美国本土鱼类的数量及其他水生物。它们也可能“入侵”与加拿大接壤的五大湖。五大湖的鱼类资源十分珍稀,而且对两国都有重要的经济价值,我们担心亚洲鲤鱼的“入侵”会造成这些珍稀物种的萎缩。
