Steve,
 
neither one of these sources will exactly fit your needs but they'll
be of some help.
 
Robert A. Daniels
1996  Guide to the Identification of Scales of Inland Fishes of
Northeastern North America. Bulletin #488 New York State Museum.
SUNY/the state education dept.
 
Cannon, Debbi Yee
1987 Marine Fish Osteology:  Dept. of Archaeology Simon Fraser
University, Burnaby, B.C.  Publication #18.
 
the book won't be much help in species identification (four
species are illustrated, pacific salmon, cod, rockfish, and
pacific halibut) it is quite good in element identification with good
line drawings of individual elements for each species.
 
Keep me posted on any other useful reps that you may get off list.
