Wild salmon are managed in Alaska for an aggressive harvest, adequate reproduction numbers, and all will die within months anyway. So we eat quite a lot of them. Of course king salmon in much of AK are not doing well over the past decade or so and I layoff them unless they are stocked in one of the "terminal harvest" areas.
I do not remember the last time I killed a rainbow.
We usually kill a lake trout or two on accident out of a big bunch and we eat those. They are eating salmon smolts in huge quantity and the biologist says it is okay to kill a lot more... But I am not buying that!
We kill and smoke a few dollies every year and their unique life style lends itself well to killing some without concentrating the pressure on any one spawning population.
A new law this year in SouthCentral AK says no pike may be returned alive to the water. Cut them up and toss the pieces back... In the Alexander Lake system they netted and killed tremendous trophy pike last year... But they are not worth attempting to eat.
