Traditional single species management aims at producing sustainable yields by regulating catch and fishing effort; however, it does not account for other important factors that can affect fisheries production, factors such as, predator-prey relationships, climate change, habitat variability, and disease. A priority goal of EBFM is foster high yields while maintaining the structure and function of the ecosystem. Because of many scientific uncertainties, the emphasis must be on precautionary management. In developing EBFM approaches in the years ahead, Houde suggests, new governance structures may well evolve to meet its requirements.
