Migration barriers, habitat destruction and changes in the ocean have led to a dramatic decline. In River \u00c4tran, extensive restoration efforts are underway to benefit the species, and in the middle of central Falkenberg, electrofishing is being carried out to locate larvae of the secretive fish."}
