Project turns spotlight on sea trout
The sea trout and the brown trout are very similar, except for one important difference: whilst the brown trout is largely a freshwater fish confined to rivers and lakes, the sea trout migrates to the ocean for much of its life and returns to freshwater only to spawn.
Because of research carried out over many years, much more is known, for example, about the salmon which can live for up to four years. However, it is believed a sea trout can survive for 12 years and might spawn six to eight times.
