I haven't checked this thread in a while so let me point out a few things:
1. I do not freeze them in salt water, I just soak them in it to remove some of the blood, they get rinsed and then frozen with enough water to cover the fillets.
2. My water and ice cubes taste fine and it is city water.
3. This funny taste only occurs every once in a while even though I do the same thing each time.
4. Fresh fish never have a bad taste so I think it is somewhere in the process.
Since my last post I started vacuum packing my crappie and will be testing the taste later this summer. I have also started using a different cooler if I have to leave them on ice for any amount of time. Thanks for all of the ideas guys.
