Salmonidae
Brook trout
Salvelinus fontinalis · 15–30 cm in small streams; 40 cm and over in productive northern water.
How it feeds
Brook trout are the most opportunistic of the salmonids and the least selective. They feed on whatever the current delivers, including terrestrial insects that fall in, and they will chase a small streamer in water no larger than a bathtub.
How to fish for it
Perfect for short rods in small water. A 2- to 4-weight and a #12 attractor dry will catch fish all day in a headwater stream, and the take is usually fearless — the problem is spooking them, not persuading them.
