Tell us about the weather lately and the pond. Lots of threads here on low DOs (low oxygen). Any thing that stirs up and moves water in the top 3 feet of the water will help. For example running a boat motor just below the surface or pressure spraying pond water back over the surface.

See this near the bottom for emergency aeration.
