Fisheries science and management services

  • Environmental impact assessments, including fish population surveys in freshwater, estuarine and offshore environments using all contemporary surveys methods.
  • Assessment of fish stocks and disease, including the rescue and relocation of fish during engineering activities and in the event of pollution incidents. We also offer restocking advice.
  • Fish entrainment and impingement monitoring and water intake and outfall screening.
  • Sampling and monitoring to support the conservation of rare and protected fish species.
  • Specialist walkover surveys to accurately quantify fish habitats and potential pollution sources.
  • Hydroacoustics, using our state-of-the-art echosounding equipment and GIS tools to assess a variety of aquatic habitats.
  • Advising on the best management options for commercial and residential developments.
  • Providing expert witness testimony in court cases and public inquiries.
  • Wide range of specialist survey apparatus ranging from electric fishing gear to oxygenation equipment and holding tanks.
  • Fish health checks.
  • Fisheries Science and Management 3

Fisheries science and management experience

  • Researching and writing a guidance manual on restoring salmon habitats in UK rivers for the Environment Agency.
  • Carrying out a long-term assessment of the impact of drinking water abstractions on fish populations in the River Dee, a study jointly commissioned by three water companies.
  • Undertaking quarterly fish surveys of the upper Mersey Estuary for seven years to evaluate the potential impact of the major new bridge crossing.
  • Carrying out a detailed study of the potential impact of a major water resources development on coarse fish populations in the River Thames.
  • Completing a study for Dwr Cymru Welsh Water on the potential for using an acoustic behavioural deterrent for the protection of the young of the twaite shad species at water intakes.
