2008-01-27 Study Sees Wild Salmon at Risk From Fish Farms (2/2)
The researchers say they used information from the Canadian government from nineteen seventy to the present. They studied fourteen populations of young wild pink salmon the * context_______ that came in contact with salmon farms. They compared these populations with one hundred twenty-eight populations that did not have such context contact.
研究人员说他们所使用的都是加拿大政府所提供的从1970年至今的数据.他们研究了和养殖场有接触的十四种野生粉色幼鲑.并拿这些与128种跟养殖场没有接触的相比较.
研究者称从1970年至今一直使用从加拿大政府获得的信息。他们研究了与鲑鱼养殖场有接触的14个种群的野生粉红幼鲑, 把它们与128个没接触过(养殖场)的种群进行了比较。
The scientists say the populations were dying out in the areas near salmon farms, but other populations stayed healthy. They know note that earlier research on this issue had similar results. Sea lice trouble travel from inland rivers to the ocean. The lice eat the muscle and skin of young fish. *____ Adult fish do not seem the ?? affected. Older bigger fish have *______ thicker skins.
科学家们说,养殖场附近地区的野生鲑群正在濒临死亡,而其他的均健康地生存着. 他们注意到早期的关于这个问题的研究有相似的结果. 海虱从内运河游向大海. 他们吃小鱼的肉和皮. 大鱼好象没有受到影响. 越老越大的鱼的皮就会更厚些.
科学家称靠近鲑鱼养殖场附近区域的这些粉红鲑种群正行将灭绝。但其余的品种却十分健康。他们注意到之前相关的研究也得到了相似的结论。海虱子通过内陆河流传播到大洋中。他们吞噬着鱼幼苗的肌肉和皮肤，而由于成年鱼有着更厚的皮肤，虱子看起来对它们没什么影响。
And fishlove owner An official of NOAA, the National Oceanian of____________ Oceanic and Atmospheric Administration in the United States, said facts do not support the new study. He said many conditions of fat affect salmon. One is the soft salt content of the water, Another is the presents presence of predictors predators that attact attack the fish. Still another is the amount of fishing that takes place in the area.
国际海洋与气象管理中心(NOAA)的一位工作人员说一些事实并不支持这项新研究. 很多因素都影响到鲑鱼. 一是水中盐的含量; 另外是有其他掠食生物的存在. 当然还有当地钓鱼情况的发生.
一位NOAA（美国海洋和大气管理和研究局）的官员称事实并不支持研究成果，他说许多条件都会对鲑鱼造成影响。一个是海水的盐分。另一个是海水中捕食者的存在会威胁鱼类的生命，而发生在此区域中捕鱼活动的总量也是原因之一。
The ?_ Demand for fresh salmon is growing. Now, almost seventy-five percent of the salmon that Americans eat comes from fish farms. And Congress is considering ??legislation that could permit many more fish farms.
新鲜鲑鱼的需求量是上升的. 目前美国人食用的鲑鱼几乎75%来自养殖场. 而且国会正在考虑立法来限制更多的养殖场.
如今，对于鲜鲑鱼的需求正与日俱增。几乎美国消耗的75%的鲑鱼来自于养鱼场。同时国会正考虑立法以批准建立更多的养鱼场。
