Place ingredients for fish bath in a large basin, making sure fish is fully submerged.

Allow fish to remain in bath at least half an hour; remove from basin and pat dry.

Place fish in a lined, large roaster pan. Generously sprinkle inside cavity of fish with salt, pepper, and sugar.

In a bowl, combine stuffing ingredients and place inside fish cavity, making sure to fit in as much stuffing as possible. It doesn’t matter if the stuffing comes out of the fish a little, just push the fish against the side of the pan to hold the stuffing in place. If you have extra stuffing, you can form it into a small ball and place in the pan next to the fish.

Sprinkle outer skin of fish with paprika, salt, and pepper, and drizzle with oil; rub into skin of fish.

Bake covered, at 350 degrees Fahrenheit (180 degrees Celsius) for one hour. Bake an additional 15 minutes uncovered, at 450 degrees Fahrenheit (230 degrees Celsius).
