- Abstract
There are millions of built structures existing today in thousands of rivers. While these structures provide important services to society, e.g., power, transportation, and water for drinking and irrigation, the structures are not without consequences for provisioning the whole of a rivers' goods and services. A major issue for these structures is their creation of barriers for fish passage. While most provide some form of fish passage, the solutions are restricted to economically important species and barriers in isolation. We are slowly accepting that there are broader ecological consequences of barriers and more holistic approaches are emerging for the planning and managing created barriers in river ecosystems. We develop a holistic and adaptive, fish passage decision-making framework that uses key science questions to inform and support the development of successful fish passage management plans for a barrier and the river ecosystem. The framework builds from the biological needs of fish for functional passage, which can then support the complex social and economic considerations that are entwined in a comprehensive management plan. The framework uses a multi-species, ecosystem focus, embraces uncertainty, and embraces an adaptive approach. We recognize this approach advocates for a paradigm shift in fish passage decision making and management, but cracks in the old paradigm are emerging, and it is imperative that operators, regulators, rightsholders, stakeholders, and science keep working together to build this new paradigm that embraces a whole ecosystem approach.
