Though the trout is one of our favourite game fish it is actually a powerful predator itself – a water leopard with the spots and sharp teeth to prove it. Young trout feed on small invertebrates, but as they grow they will start to prey on other fish, and the biggest will even take small birds and mammals that venture into the water.
Look out for them in fast moving streams and rivers, heads pointing into the current as their powerful bodies hold them in place. People used to think there were two distinct species – brown trout and sea trout. But we now know they are actually just different strains of the same species that have found different ways of surviving. Sea trout follow a salmon-like existence, migrating to the Altantic to feed for a number of years before returning to the rivers where they were born to breed. They tend to be greyer than the aptly named brown trout, which stay put in their home rivers for the whole of their existence.
