We’ve had good luck with the Food Saver, but we’ve never done whole, fresh-caught fish. Are you going to freeze?
You should be able to pat it dry, stick it in there, and seal - the newer ones have a ‘moist’ setting. Husband assumes the vacuum action will be a little more gentle on that, but the vacuum-seal won’t be as complete, so if you’re freezing long-term, you might get some freezer burn.
They have one called a ‘Gamesaver’ that might have different features, but we don’t have experience with it:
I’ve read the negative comments on lots of top brand sealers on Amazon and on Walmart - they give up after five or six sealings (not all at once either) - the one’s that have this moisture button don’t work very well. I’ll check out your recommends. And yes, the food is to be frozen and also dried stuff for emergencies.
I’ve used the foodsaver with wet things, even whole wet fish. It might take a time or 2 but the bags do seal. They also make bags with an absorbent strip at the bottom. Or you could fold a paper towel strip and lay it along the bag opening just below where you will seal.
I finally got out of the dark ages and got a food saver. I’ve only used it once, to vacuum seal my oxygen absorbers in a mason jar. I really just feel more comfortable with mylar and oxygen absorbers. But I bought some replacement bags on Amazon to force myself to start using it… Maybe tomorrow :-)
I actually bought it for a business that I decided not to even start. Too many regulations, taxes, fees, licenses, insurance… It’s just not worth it in this day and age. I’ll have to go get a real job. If big brother ever stops interfering, I would love to start it one day.
