A study from Canada says fish farms are a threat to some populations of wild salmon. It sensed says the danger is from sealines sea lice which are small organisms that feed on fish.
一项来自加拿大的研究称很多养鱼场正在遭受野生三文鱼数量的威胁.这种威胁来自于海洋中的寄生虫.它们是用来喂鱼的小生物.
一项来自加拿大的研究宣称鱼场对野生鲑鱼的一些种群来说是一种威胁。该研究称危险源于海虱，它们是食鱼为生的微小生物体。
The researchers say this parasize these parasites commonly in fact infect salmon raised in farms but also attack young wild pink salmon that swim nearby. Their research suggests that if these out breaks outbreaks continue local populations are of wild pink salmon will all but disappear.
研究人员说这些寄生虫通常会影响三文鱼的正常繁殖,而且还会攻击在附近巡游的三文鱼幼虫. 研究中提到如果这种灾难不解决,当地三文鱼幼虫会全部消失.
研究人员说这些海虱一般会感染养殖场饲养的鲑鱼，但是它们也会侵袭到在附近游动的野生粉鲑（细鳞鲑鱼）鱼苗。 他们的研究显示，如果（海虱）爆发继续，当地的野生粉鲑种群将几近消失。
Experts are * debating the study publishing send the published in Science magazine. The Canadian govenment and some American experts say no direct link has been found between sealines sea lice and salmon deaths.
专家们对于这份发表在科学杂志上的文章正在进行辩论. 加拿大政府和一些美国专家称在海洋寄生虫与三文鱼灭绝之间还没找到任何直接的联系.
该项研究发表在《科学》杂志上，专家们正就此展开讨论。加拿大政府和一些美国专家说仍未发现海虱和鲑鱼死亡之间的直接关系。
Marken * Martin Kckosek, of the university about *of Alberta in admenten Edmonton led the study team. The researchers relay relate the grows growth of fish farming of off British Columbia to loasis losses in young wild salmon. The number of fish farms in the area has increased sharply. The researchers say ?lice commonly kill more than eighty percent of pink salmon in the areas they studied. The fish in these col? coastal areas swim past many fish farms before entering the open occean.
埃德蒙顿的亚伯达大学的Martin Kckosek是研究团队的负责人. 研究成员们将英国哥伦比亚养鱼场繁殖率和幼虫的减少联系起来. 当地养鱼场的数量增加迅速. 他们说寄生虫害死80%的三文鱼. 沿海地区的鱼在进入海洋之前就已经从鱼场游走了.
埃德蒙顿市阿尔伯塔大学的Martin Krkosek 主持该研究小组。研究人员把不列颠哥伦比亚省附近鱼场的发展和野生粉鲑鱼苗的死亡联系起来。该区域的鱼场数目已大幅上升。研究者说在他们所研究的地区，海虱导致80%以上的野生粉鲑死亡。这些沿海区域的鱼进入辽阔的海域之前游经很多渔场。
