Standing crops of fish in representative Oregon farm ponds were estimated by marking and recapture or by draining and enumeration. Most of the ponds were in the Willamette Valley, but a few were in central and southern Oregon. The average standing crop of bluegills (Lepomis macrochirus) was about 130 pounds per acre, and was similar to standing crops reported by workers in other states. The average standing crop of largemouth bass (Micropterus salmoides) for 12 ponds was 104 pounds per acre. Central Oregon ponds appeared to support more pounds of bass per acre than western Oregon ponds.
