A number of years ago while fishing several streams on Kodiak Island for Dolly Varden we had trouble getting them to take anything. The bottom was literally black with them and they could be seen flashing in the pools as they fed, yet they would not take anything. An ordinary Pheasant Tail Nymph was the only thing that occasionally worked. A few were kept for dinner one night and the stomach contents were amazing; there were sea lice in the stomachs, only sea lice, and lots of them.
