I think it comes from...and I've heard this. If you ask the mandate of someone who's a fish and game and wildlife worker, i.e., what is their purpose, they can list it off really quickly. Within that is to protect and enhance the livelihood of fishermen. If you ask someone who's maybe in management or regulation at DFO, they're not quite sure what their mandate is.
