Get yourself one of those vacume pack machine that takes the air out of a heavy plastic bag. We fish a lot in Summer and sometime catch many Striped Bass, Bluefish. I bring the vacume packer machine with us on vacation. When we get back from a fishing trip, I fillet all the fish, then put it in serving size bags and run it through the Vac machine. Some we eat within the first few days but the rest goes into the freezer for later. It's a good investment.
