Stream Salmonids on the Cormorant ( Phalacrocorax carbo ) Menu
Predation from endemic predators is a natural regulating factor for fish species in rivers and lakes, but recently there has been a great increase in the populations of some of these predators, and predation is now threatening particularly populations of Atlantic salmon (Salmo salar), brown trout (...

Predation from endemic predators is a natural regulating factor for fish species in rivers and lakes, but recently there has been a great increase in the populations of some of these predators, and predation is now threatening particularly populations of Atlantic salmon (Salmo salar), brown trout ( Salmo trutta ), North Sea houting ( Coregonus oxyrhynchus ), and grayling ( Thymallus thymallus ) throughout Europe.
