I typically don't keep fish frozen for very long. I usually give them to friends on the pier, or give them to other friends, cleaned, packaged and ready to cook. But I keep a few packages in my fridge-freezer for spells when we have bad weather.
I utilize a vacuum sealer. I highly recommend it for keeping fish fresh-tasting. I had wanted to, as an experiment, try eating fish that had been frozen a few months, since May. So I kept a package of spadefish for that purpose.
Spadefish have an area of darker meat that had me curious as to whether it would have an off-putting taste/aftertaste after months of freezing. I'm here to tell you that the fish was absolutely as delicious as if I had cooked it fresh out of the gulf the same day! I prepared it fried, but I suspect that it would have been equally wonderful prepared in a number of ways.
So -- it's very likely that I'll be fishing for spadefish again, soon. I've been out of commission this week (lower back strain), but I'm eager to get out there and catch a new batch for the freezer!
I've had great luck with whiting, keeping them for a month or so. But does anyone else have another favorite fish that freezes well?
