I too have multiple freezers and use the quart bags with just enough water to cover fish. Use salt to soak the fish in frig but then don't use any when I freeze them. BTW Sams has their good vacuum sealer and bags on sale right now for $50 off. Bought mine yesterday and will be vauuming mine from now on. But when i do freeze with bags squeeze out all the air and it doesn't take up as much room in freezer.

bought one a year or so ago the one Bluegabe touted but it worked for a few times and then won't vacuum at all and they have no CS so just having to eat it. Oh well.
