Abstract

ABSTRACT Mechanical fish feeders were placed throughout the littoral zone of a flood control reservoir and operated for four growing seasons to improve growth rates of bluegill. Analysis of previous year growth increments suggested that only age 5 bluegill benefited from the supplemental feeding program. To validate utilization by the target species, toxic fish bait was applied through the feeders. Gizzard shad were the only species captured through this method. These results suggest that the presence of gizzard shad may reduce the effectiveness of supplemental feeding programs for bluegill.
