Saskatchewan Freshwater Fishes: A Waterproof Folding Guide to Native and Introduced Species
This is a great little guide. It's small, waterproof, and informative. Great as a quick reference to throw in your tackle box or on your boat. Written by the University of Regina's own Dr. Christopher Somers. I've enjoyed mine and highly recommend. View on Amazon
