Efforts to enhance energy flow in lakes and reservoirs are directed at forage‐fish management as the mechanism of mid‐level energy transfer. Management techniques and strategies are not highly evolved. Conventional management has emphasized exotic introductions of predators or prey, often with more attention to perceived attributes than potential consequences. The ideal forage species, resident or introduced, should be (1) prolific, (2) stable in abundance, (3) trophically efficient, (4) vulnerable to predation, (5) non‐emigrating, and (6) innocuous to other species. Standard procedures for evaluating forage species prior to introduction should be considered as well as the development of methods of control. Techniques for predicting fluctuations in forage abundance may be warranted if responsive predator‐prey manipulations can be developed.
