Stream spawning of Arctic charr in Scotland
Abstract – Scotland is a stronghold for Arctic charr, with about 200 freshwater, wholly loch‐resident populations, most of which have yet to be studied. To date, no anadromous populations or individual sea‐run charr, have been reported. In Scotland, most Arctic charr spawn in stillwater, during autu...
