For marinade: In a small bowl, combine basil, oil, oregano, thyme, garlic, lemon zest and juice, tangerine zest and juice, kosher salt and pepper. Pour marinade over fish, turning the fish to coat. Chill for 30 to 60 minutes, turning once. Remove fish, reserving marinade. Transfer marinade to a small saucepan. Bring to boiling; reduce heat to low. Simmer, uncovered, for 1 minute.
