It depends on the thickness of the fillets.
I've never smoked a whole fish but with fillets of Tailor or Spotty/School Mackerel, I leave them in for roughly 7 or 8 minutes.
Leave the skin on. It keeps the flesh moist and tasty and gives you the benefits of all those healthy Omega oils.
With the thicker Spaniard fillets... 10 minutes at the most.
