Fatih, I've never heard that aeration has an effect on mosquito larvae or other bugs.
The cycle of pond life includes insects. Here's the way it works.
The lowest level is phytoplankton which is microscopic plants. It is fed on by zooplankton which is microscopic animal life(bugs). That is fed on by other larger microscopic animals(more bugs). Somewhere in that food chain would be a mosquito larvae. That continues up the food chain until those bugs are eaten by tiny fish that are eaten by larger fish. Everything in a pond is eaten by something bigger. Actually 98 to 99% of all small fish are eaten before they get large enough for us to utilize. But that's OK and it keeps the pond from becoming overcrowded.
Unless there is something about the large bugs that makes them unpalatable, fish should soon eliminate them when they hit the water.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
Without a sense of urgency, Nothing ever gets done.
