Name: Brown Trout
Scientific name: Salmo trutta
Nature Stars: 60
About: A medium to large fish, growing up to 30-40cm. Brown Trout lives in fast-flowing, stoney and gravelly rivers. It is a brownish-silvery fish, spotted with black and red spots. A predatory fish, feeding on insect larvae, small fish and famously on flying insects such as mayflies and damselflies, which it famously jumps out of the water to catch.
How to identify: Much smaller than Salmon, and smaller than Rainbow Trout, from which it can be told by plain, dark tail fin and the lack of the purpley side stripe.
Where: Found throughout the country
Fantastic fact: Brown Trout feed mainly in the late afternoon and evening, when they famously jump out of the water to catch flies.
