This male shorthead had highly developed tubercles on his anal and caudal fins.
I was primarily fishing soft hackled wet flies on my 6 wt. Fish were actively taking flies on the lift, which is indicative of an emerging nymph. I mixed it up and tied on a bunch of different patterns to see if these fish were keying in on anything specific. That was not the case, as they took everything from a soft hackled prince nymph, antron special, gold ribbed hare's ear, to a san juan carp killer.
