如果将关注食物链顶端和底端的方法同时应用到全球性数据上,那么,科学家们得出的结论是,过去10年的工业捕渔更偏向捕食低食物链鱼类,而对高食物链等级的鱼类而言,它们的食物总量减少了将近一半,倘若按照食物链理论的逻辑,现存高食物链等级的鱼类总数是增加了而不是减少了,因此,不能够简单地认为,工业“捕渔”导致鱼类总体的数量减少。
Applying both methods to worldwide data, the scientists say industrial fishing over the past decades has not simply worked its way downwards from the top of the food chain -- it has gone upwards, too.
