No. If properly sealed it will last in the fridge. No reason to freeze it.
Ummmmmm , you've obviously never seen her bitch and moan about vac sealers, bags blah blah blah, what's best what keeps (fish fresh) the best etc..... So, that being said, I vac seal all smoked fish.... Just took some to work the other day, 3 years old, lasted less than 5 minutes....Grin suppose refrigerated 3 year old smoked salmon shoulda been smashed that fast????? Haha
Nothing makes it to three years old in my house. I never found it that challenging to vac seal food! But I also have never had a problem eating frozen fish either. Sh_t just isn't that difficult to figure out.
First Elk I ever killed my buddy said that will feed you all year. It lasted 5 months. Probably wouldn't have lasted much over three months if I had not had a couple Deer and Prong Horn to eat as well. I may not be good at anything else but I can sure has hell eat with the best of them.
