About a year ago I was granted fishing access to a small 1/4 acre circular pond that was stocked about 8 years ago. The owner's estimation of maximum depth is about 10 feet in the middle and it's basically a featureless bowl shape with a large fountain in the middle. The shoreline is riprapped with softball sized rocks out to a depth of about 3 feet, and there is no other structure in it that the owner knows of.
My buddy and I fished the pond three times last year and had no problems catching many bluegill with an average size of 6". We also caught 8 largemouth bass that averaged 12" and one bass that was a solid 2.5 pounds. We released all the bass and kept 30 bluegill on one of our trips.
Given this limited knowledge of the pond, can you give me any suggestions on what would be a sustainable harvest of bluegills a few times a year?
