If you look at the northern rivers, the Labrador rivers, the northern Newfoundland rivers, you probably won't see that dramatic fluctuation in abundance. Western Arm Brook is a small river on the northern peninsula of Newfoundland. It's been monitored since the early 1970s, and it's been tracking long. The big change happened when we closed the commercial fishery. All of a sudden the fish are returning to Western Arm Brook in higher numbers, and they've been maintaining higher numbers. So those northern populations seem to have been less affected by these shifts of ocean conditions over the last 40 years than we've seen in the southern populations.
