Brown or Sea Trout Salmo trutta
The Brown Trout (Salmo trutta) occurs in two principal forms in Suffolk: the resident freshwater brown trout of clean rivers and streams, and the sea trout – the same species in its migratory, sea-going form. Sea trout ascend Suffolk's rivers, including the Stour, Orwell, Deben, and Waveney, to spawn in clean gravelly reaches, having spent time feeding at sea. Both forms have declined through river engineering, water quality issues, and reduced spawning habitat. Habitat restoration, improved water quality, and fish pass installation are central to recovery efforts across the county's river catchments. Image: © Christa Rohrback, iNaturalist.
