Prey-Predator Relations In Crooked Creek Bay. Barkley Lake. Kentucky
Available prey-predator ratios (API P) in Crooked Creek Bay indicated a deficiency of prey for predators (largemouth bass equivalents) 200 mm long (total length) or less. Analysis of samples collected after the application of rotenone to small coves led to overestimates of available prey. Application of adjustment factors to account for differences in fish distribution in coves and in open water improved AP/ P estimates based on small-cove samples. After reviewing previous food studies, we redefined crappies longer than 210 mm and catfishes longer than 390 mm as predators. Revised AP/ P...
