Salmonidae
Resident brown trout
Salmo trutta (non-migratory) · 15–35 cm in most rivers, with exceptional fish to 60 cm in fertile spring creeks.
How it feeds
Resident browns spend their whole lives within a few hundred metres of where they hatched, which means they learn. A resident brown that has refused a fly will remember the shape of it, so changing size and silhouette matters more than changing colour.
How to fish for it
Approach from downstream, stay low, and cast only when a fish is actively feeding. On spring creeks the whole game is presentation: a 5-metre leader, a single small fly, and no false casting over the water.
