I have dozens of 2-4lb frozen pieces of frozen salmon and halibut (fileted, boneless, skin-on). The lodge cryovac'd them for us, then shipped them. They've been frozen since they were caught.
I'd like to somehow reportion them into smaller ~1lb pieces because we're a small family, and there's no way we can eat 2-4lbs of fish in 2 days.
My only thought is to use a saw of some kind to saw the fish (frozen, so I don't thaw and refreeze), then cryovac it again (I have one at home) to put back in the freezer.
Please share any tips, suggestions, or personal experiences with dealing with this sort of thing. Thanks!
