Are manmade obstacles in marine environments causing migration delays and predation hotspots for migratory fish?

Behaviour of veteran sea trout Salmo trutta in a dangerous fjord system

The behaviour and survival of sea trout _Salmo trutta_ L. in marine environments remains scarcely described despite the widespread ecological and cultural importance of the species. We tracked 160 wild, post-spawned sea trout in 2 Danish river systems using acoustic tags to examine their behaviour in a fjord system characterized by a scarcity of refuges and a high abundance of mammalian and avian predators.
