I always wanted to paint trout; they're so wonderfully colored. I haven't been fishing since 1991, but enjoyed it for years before that. Oil on canvas. Trout paintings with matching frames make a nice set of subspecies of trout. Trout who have modeled for my paintings - with Pat Clayton's permission - are found on the pages of The Fisheye Guy -
