Abstract:

Stocking of largemouth bass fingerlings has not generally regulated crappie numbers in recently stocked farm fish ponds. Experiments on the stocking of year-old largemouth bass to control crappie populations were conducted during the 1971 and 1972 seasons. Nine 0.25-acre ponds and three ponds between two and three acres in size at the Fisheries Research Unit of the Auburn University Agricultural Experiment Station were used. The reason for poor crappie control was determined to be the inability of young-of-the-year fingerling largemouth bass to prey upon young-of-the-year black crappie which were too large to be eaten. Experimental findings indicated that crappie stocked as fingerlings would spawn as one-year-old fish rather than as two to three year old fish as reported in the literature. Experimental evidence indicated that the stocking of year-old largemouth bass was no more effective in controlling black crappie populations than the stocking of young-of-the-year largemouth bass fingerlings. Unidentified factors did influence fish populations in the experimental ponds. If these factors could be identified and manipulated they possibly could be used to control crappie populations. Life history information concerning nesting behavior, sex ratios, and sexual color dimorphism of black crappie was collected during the study to assist in formulations of new management techniques.
