Upstream and downstream fish passage experience in France
Plans for the restoration or enhancement of anadromous fish stocks were initiated in France more than 15 years ago. A 1984 law concerning freshwater fisheries requires that any obstruction in streams or parts thereof, in the list specified by decree, must include facilitaties to ensure the passage o...

Plans for the restoration or enhancement of anadromous fish stocks were initiated in France more than 15 years ago. A 1984 law concerning freshwater fisheries requires that any obstruction in streams or parts thereof, in the list specified by decree, must include facilitaties to ensure the passage of migratory fish. As a result, more than 400 fish passes were built or improved, and significant advances in the design of upstream fish passage and facilitaties have occured during the last 15 years. This chapter provides an overview of the functional features and design parameters used in the different types of passage facilitaties : Denil fish passes, pool fish passes, fish elevators and natural bypass channels. The relative advantages and drawbacks of each type of fish pass are discussed, with reference to the requirements of specific migratory species and site specific constraints. Emphasis is placed on the problem of maintenance. The various techniques used in France to evaluate the existing or newly constructed fish passes, as well as the topic of downstream migration at turbine intakes, are reviewed.
