S.S.
I assume they are still frozen? If so don't wory I have had the same thing in half of my freezer. I think what you are seeing is ereas on the skeins that have a higher moister content (didn't brine properly) hat have allowed ice crystals to form in the individual egg. Try making sure you either butterfly the skeins more or you can pre cut the clusters you fish with before they go into the brine. When you thaw the eggs you should see them return to thier translucent look.

Good luck
