Fish Passage, Dam Impacts and Fishway Evaluations

We have sixteen years of experience monitoring fish passage and the effects of dams and weirs on fish and other wildlife. We use remote monitoring techniques such as radio telemetry, acoustic telemetry, physiological telemetry as well as overhead and advanced underwater videography to unobtrusively observe animals. We also use active and passive capture techniques to collect, inventory and enumerate study organisms while characterizing and describing used and available habitat under various environmental conditions. Experienced teams of technicians collect and analyze data, and a proven team of scientists prepare reports and scientific papers. By understanding effects of barriers to fish migration, and the effects of different types of habitats that exist upstream and downstream from river barriers, we can suggest strategies that selectively increase permeability, and imperceptibility of migration barriers for fish.
