I'm still a little confused - you skim your pond everyday? And you find lots of mosquitoes in your pond? Or you have lots of mosquitoes in your yard and thought the fish would take care of them? Because unless you teach your fish to patrol your yard, they can only deal with the larvae that hatches in the water. And quite honestly, a pond as small as yours would have little affect on the mosquito population one way or another.
If the surface of your water is moving, the mosquitoes won't choose it as a place to lay their eggs. Like
@Mmathis suggested - check your yard for any sources of standing, stagnant water and eliminate them. Even a shallow puddle or a bucket with a small amount of rainwater can be a mosquito nursery. But there's really only so much you can do to eliminate mosquitoes. In Illinois we jokingly refer to the mosquito as our state bird.
We have actually found that the dragonflies that are attracted to our pond do a great job of controlling the mosquito population - whenever we have a surge of mosquitoes, we see a resultant influx of dragonflies.
