1. Whisk 2 tablespoons oil, vinegar, cilantro, 2 teaspoons soy sauce, ginger and sugar in medium bowl. Cut peel and white pith from oranges; discard. Holding oranges over bowl to catch juices, cut between membranes to release segments into bowl. Add fennel and onion; toss gently. Season with salt and pepper. (Salsa can be made 3 hours ahead. Cover; chill.)
2. Prepare barbecue (medium-high heat). Mix 3 tablespoons oil, 1 tablespoon soy sauce and garlic in glass pie dish. Turn fish in oil mixture to coat. Sprinkle fish with salt and pepper. Grill until just opaque in center, about 3 minutes per side. Transfer to plates. Spoon salsa over.
