Lots of old threads on this site. Do a search for "roe" or something similar and there will be info to read until your eyes fall out.
I've tried a few different methods. What works best for me is to store the cured roe in sealed (just screwed tight) mason jars in the deep freezer. The night before fishing I'll take a jar out and put it in the fridge. In the morning I'll dump the jar into a plastic container I use to hold roe while fishing. Any roe left over goes back in the mason jar when I get home. I top up/add borax if there is any exposed roe. IMO any roe that is not covered in borax will get freezer burned. If I'm going out again the next day I'll just leave the container in the fridge. Any more than a day I'll pop it back in the freezer. I've thawed/froze the same roe more than 5 times and the remainder of it was still fine and caught fish no problem.
Borax does protect your roe from freezer burn, and prevents it from sticking together. But it does dry it out. I never keep any more roe in the fall than I feel I can use up before next fall. Any roe that has not been used up from last year by the following year's fall/winter fishery is usually a bit too dried up for my liking, and unfortunately gets tossed.
I tried the vacuum seal method and did not like it as the unused roe from the day needs to be re-sealed. Pain in the buttocks. Plus if the roe is packed in borax I don't think the freezer burn will get to it anyway, so IMO it is unnecessary to further vac seal it. Some guys toss a lit match in the jar with their roe to suck up the remaining air. I don't bother with this as I feel the borax protects it adequately.
Lastly I will add I'm a believer in curing fresh roe ASAP, then freeze it. I've tried to freeze fresh skiens and then later thaw and cure them. I did not like the result. IMO the uncured roe gets damaged if it is frozen and not cured.
