Besides Alaska, where can I go Halibut fishing?

There is a population of Halibut in the North Atlantic. Think Newfoundland, Labrador, Greeenland, Iceland, etc.

But I am pretty sure the Pacific Halibut is much more populous. Google a charter in Newfoundland and see if they list Halibut among their species.

I caught a 60lb halibut out of Westport, WA while salmon and lingcod fishing. They have halibut season but it's pretty short. The boat we chartered was called the "Slammer".
