This week’s winner is Denver’s own Jeff Johnson. Jeff submitted this great shot of a BC bull trout and also this video to go along with it. New to bull trout? Here’s the skinny:

The bull trout, Salvelinus confluentus, is a char, native to northwestern North America. Like other species of char, the fins of a bull trout has white leading edges. Its head and mouth are unusually large for salmonids, giving it its name. Bull trout have been recorded measuring up to 41 inches in length and weighing 32 lbs.

Today’s prize: a Trout's signature Fly Box and a pair of fishpond koozies (with the temperatures pushing into the 60s again this weekend it is important to keep those beverages cold!).
