Ion deficit restricts the distribution of brown trout (Salmo trutta) in very dilute mountain lakes

摘要

The current study is, according to our knowledge, the first study indicating that ion deficit is an important restrictor to the distribution of brown trout populations in very dilute mountain lakes. The brown trout populations in the study lakes may be able to survive solely due to traces of air borne sea salt spray. (C) 2016 Elsevier GmbH. All rights reserved.
