Mortality of eels Anguilla anguilla in a large shallow lake in France due to predation by the cormorant Phalacrocorax carbo was found to be moderate when compared to fishery catches over a 9 year period. The results show that, contrary to previous extrapolations made at the pan-European scale, P. carbo predation in shallow lakes is not invariably a major contributor to A. anguilla mortality, even in the presence of large colonies.
在法国的一个大型浅湖中，鳗鱼（Anguilla anguilla）由于受到鸬鹚（Phalacrocorax carbo）的捕食而死亡，与 9 年的渔业捕捞量相比，死亡率适中。结果表明，与之前在泛欧范围内进行的推断相反，即使存在大型鸬鹚栖息地，浅湖中鸬鹚的捕食对鳗鱼死亡率的影响也不一定是主要因素。
