This study reports descent of Atlantic salmon Salmo salar fry from their natal streams to brackish waters of the Baltic Sea and their use of this environment as an alternative rearing habitat before ascending back to freshwater streams. To the authors' knowledge, residency in a brackish environment has not previously been demonstrated in S. salar fry. Recruitment success and evolutionary significance of this alternative life-history strategy are presently not known.
本研究报告了大西洋鲑鱼苗从其出生溪流洄游至波罗的海咸淡水区域，并在溯游回淡水溪流之前将该环境用作替代育幼栖息地的情况。据作者所知，此前尚未证实大西洋鲑鱼苗会在咸淡水环境中栖息。目前尚不清楚这种替代生活史策略的补充成功率和进化意义。
