Hi- It does not say so on their FB page, but I assume that these are previously frozen, due to the fact that you can't fish in Alaska this week. They could also be frozen now, which could solve your problem.
I am not sure if you are supposed to refreeze fish that has been thawed. I think it could affect quality, but I am not a fish expert. You might try reposting this question in the shopping and cooking section, which has more traffic. Hope this helps, Nancy
