Made a video of how I smoked some frozen whitefish I had and turned out really well. About 5 pounds of whitefish, 8 cups of water, a cup of kosher salt, 1/2 cup brown sugar and teaspoon of garlic salt. Brined for 16 hours and put on smoker at 150 for three hours with maple and hickory cause that's all I could find. The pic shows the end product and this video shows the whole process.
