An improved apparatus for and method of aerating fish ponds utilizes a portable, wheel mounted, tractor drawn and driven pumping apparatus adapted to be backed into a pond to submerge the pump intake with the tractor remaining on the bank adjacent the water's edge. The pump is driven from the tractor power take-off to deliver a high volume, relatively low-pressure water output to a discharge manifold adapted to discharge the water in two opposed streams generally parallel to the bank of the pond and to simultaneously discharge water in an upward direction as a spray to absorb oxygen from the atmosphere before falling back into the pond. The apparatus can be easily moved and quickly positioned for emergency operation to aerate a pond and prevent fish, searching for oxygen in the shallow water at the edge of the pond, from beaching themselves and dying.
