Melt butter in large saucepan over medium-low heat. Add fennel, potato, onion, and leek. Cover and cook until vegetables are just tender but not brown, about 8 minutes. Add flour, bay leaves, and thyme; stir 1 minute. Stir in clam juice, cream, and milk. Simmer until chowder thickens slightly and flavours blend, about 10 minutes. Mix in lemon peel; season to taste with salt and pepper. DO AHEAD: Can be made 1 day ahead. Cool 30 minutes; cover and refrigerate.

Toss celery, shallot, parsley, 1 1/2 teaspoons lemon juice, lemon peel, and smoked oysters in medium bowl. Season celery-shallot mixture to taste with salt and pepper.

Combine 3 tablespoons butter, thyme, and 3 teaspoons lemon juice in small saucepan. Whisk over low heat until butter melts and sauce simmers; season with coarse salt and pepper. Remove from heat. Melt 2 tablespoons butter in large nonstick skillet over high heat. Sprinkle fish with coarse salt and pepper. Add fish, skin side down, to skillet. Cook until skin is crisp and fish is just opaque in centre, drizzling lemon-butter sauce over, 6 to 7 minutes.

Rewarm chowder over low heat; discard bay leaves. Divide chowder among 4 shallow bowls. Place fish, skin side down, in centre of chowder. Stir panko into celery-shallot mixture; spoon over fish and serve.
