Being as how the battlestation hadn't been completed yet it's more than likely that it didn't have a contingent of starfighters yet. I would imagine that, being as how the Emperor was already aware of the Rebel assault, he would have just brought the fleet in and not transferred any starfighters, since it would just be a wasted effort. No need to move them when they're already there.
