DIRECTIONS Prepare fish: Simmer raisins in vinegar in a small saucepan until raisins are plump,3 to 5 minutes, then cool.
Cook onion in 1 tablespoon oil in a 12-inch nonstick skillet over moderate heat, stirring occasionally, until softened, 4 to 6 minutes. Remove skillet from heat and transfer half of onion to a9-inch square glass or ceramic baking dish with a slotted spoon, spreading evenly. Reserve remaining onion.
Cut fish into 6 equal pieces. Pat dry and season with salt and pepper. Spread potato starch on a plate and dredgefish in it, shaking off excess.
Heat remaining 1 1/2 tablespoons oil in skillet over moderately high heat until hot but not smoking, then sauté fish, skin sides down, until lightly browned, 1 1/2 to3 minutes. Turn fish over and sauté until lightly browned and just cooked through, 1 1/2 to 3 minutes more.
Arrange fish on top of onion in baking dish, then top with reserved onion and drizzle with raisins and vinegar. Cool completely, then marinate, covered and chilled, at least8 hours. Bring to room temperature.
Make salad: Tear enough fennel fronds to measure 1 tablespoon. Trim stalks flush with bulb and discard stalks. Quarter bulb lengthwise, then cut lengthwise into paper-thin slices with a mandoline or other manual slicer. Transfer slices to a bowl and toss with radish sprouts.
Whisk together vinegar and oil, then whisk in sugar and salt and pepper to taste. Toss vegetables with half of dressing and divide among 6 plates.
Remove onion from top of fish, reserving it, and put a piece of fish on top of each salad. Mound all of onion and raisins on top of fish, then drizzle with remaining dressing and sprinkle with fennel fronds.
Cooks’ note:
• Fish can be marinated up to 2 days.
