Look for fish that's 1 to 1 1/2 inches thick. It sounds counterintuitive, but farmed fish is a better choice when raised inland, in recirculating water (rather than in crowded netpens in the wild). At the market, ask your fishmonger where the fish comes from.

Preparation
Step 1
Whisk butter, juice concentrate, vinegar, and saffron in small saucepan to blend. Season butter to taste with coarse salt and pepper. DO AHEAD Can be made 2 days ahead. Cover and chill.
Step 2
Using small sharp knife, cut diagonal slits on both sides of fish at 1-inch intervals. Arrange fish on rimmed baking sheet. Sprinkle fresh orange juice and salt into slits and cavities of fish. Fill cavities with orange slices (about 3 per fish). Cover loosely and let stand at room temperature at least 30 minutes and up to 1 hour.
Step 3
Spray grill racks and fish generously with nonstick spray. Prepare barbecue (medium-high heat). Place saucepan with orange-saffron butter at edge of grill to warm through, stirring occasionally. Arrange fish on barbecue. Grill until just opaque in center, about 5 minutes per side. Transfer to plates. Serve with warm seasoned butter.
