Pictures of Trout, Salmon, and Grayling Underwater, Page 4

There's one small brook trout running with this school of minnows at the head of a crystal clear spring.

Two young of the year brook trout hide in a little spring hole in a remote, crystal-clear small stream.

This isn't really an underwater picture, but a picture taken into my aquarium of midge larvae which lived in the silt I used for substrate. Each larva has a little tower of detritus (Detritus: Small, loose pieces of decaying organic matter underwater.) built up along the bottom, while the bare larva waves around from the top.

This simple rubber-legged foam beetle is one of my favorite flies for Arctic grayling. It's quick to tie so I don't mind losing one or two on snags. It's durable, so one fly can last a hundred fish or more. It never needs floatant to ride the surface well. Most importantly, it catches fish, although grayling often hit almost anything. The bold profile and attention-grabbing plop of the beetle, I think, draw fish from farther away than a more subtle fly might, and it often draws unusually savage strikes.

This before-and-after-image-enhancement picture helps appreciate the trout's camouflage.

This tiny brook trout fry lived in a crystal clear nursery area where a large spring flows straight from the ground.
