  1. Preheat the oven's broiler and set the oven rack about 6 inches from the heat source.
  2. Melt 1/2 cup of butter in a large skillet over medium heat. Stir in the green onions and mushrooms, and cook until the mushrooms have softened, about 5 minutes. Stir in the shrimp and walleye; cook and stir until the shrimp have begun to turn opaque, about 2 minutes. Add the lobster and crab, and cook a few minutes to heat.
  3. Stir in the sherry and white wine. Bring to a simmer, and cook for 2 minutes. Once the shrimp and walleye are no longer translucent in the center, stir in the cream of shrimp soup, half-and-half, 1 cup bread crumbs, and Cheddar cheese until the cheese has melted, and the mixture is bubbly. Pour into a casserole dish, and sprinkle evenly with 1/2 cup breadcrumbs and the Parmesan cheese. Dot with the pieces of cold butter.
  4. Cook under the preheated broiler until the butter has melted and the bread crumbs are golden brown.
