Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In this study, 34 anadromous brown trout (sea trout) <italic>Salmo trutta</italic> were equipped with acoustic transmitters in order to examine whether they performed avoidance behaviour in response to a CFT Legumin (rotenone) treatment in the Norwegian River Vefsna. Migratory behaviour of the <italic>S. trutta</italic> was monitored by use of 15 automatic listening stations and manual tracking in the lower part of the river, in the estuary and in the fjord. None of the studied <italic>S. trutta</italic> survived the rotenone treatment and no indications of successful avoidance behaviour were observed.</p> </abstract>
