Rhodes, this is my first year fishing salt water so I don't know anything about sand trout???I think the debate was also about freezing sand trout vs specs. I also freeze specs in water and they taste great for months afterwards but I had a very bad experience with sand trout after being frozen for months.....they were not edible. Have you ever tried to freeze any sand trout?
I never freeze my fish in water. It is very bad for the fish. It is not even good to have water in your ice cooler. Dry vacuum sealed freezing produces better fish. Ask any trained chef.
I read somewhere--maybe GON?--to freeze filets first, then come back and
fill the ziplock with water, the next day.
This has worked well for me. Texture is nearly identical to same-day catch,
and the ziplock bags take less water & space this way, too.
