If Atlantic salmon may swim upstream and spawn multiple times in their life, why aren’t there millions more Atlantic salmon than Pacific salmon that die after spawning in freshwater?

Question

Am I missing something here? — I’ve seen the salmon runs in Alaska and they are incredible. Yet I’ve never seen any footage of anything like it concerning Atlantic Salmon.

Answer 1

They were over fished and polluted out of their habitat. Most all runs in Atlantic North America are extinct, there might be a few in northern Maine. But humans killed most all of them. Some Pacific salmon were even moved there trying to re-establish runs.
