To prepare the grill for indirect grilling, heat one side of the grill to high heat.
Combine Bärenjäger and the next seven ingredients in a large bowl and stir. Place the salmon fillet into a large plastic zipper bag and pour the mixture into the bag. Marinate in the refrigerator for 30 minutes.
Remove the fish from the marinade. Place the fish on the lightly oiled plank, top the apricots; sprinkle the Caraway seeds and grill 20 minutes or until fish flakes easily when tested with a fork.
