The Adriatic salmon faces a number of threats, including overfishing for sport and for food, as well as habitat destruction and competition with introduced species (1).
Accidentally introduced trout (often escapees from fish farms) can be aggressive predators, which outcompete the Adriatic salmon for food and suitable areas of habitat (2). Hybridisation with these invasive trout is also a concern (1).
This already endangered species is further threatened by the destruction of its habitat (1). Dams, created for hydroelectric power, block the movement of the Adriatic salmon up and down rivers as it searches for food or suitable areas in which to spawn (2).
Climate change also poses a long-term threat to the Adriatic salmon (1), as an increase in global temperatures is predicted to result in a decrease in freshwater in the Mediterranean basin region (6).
