The Challenge

Fish ecology and commercial fisheries are a key consideration for freshwater and marine developments from feasibility assessments and Environmental Impact Assessments (EIA) through to post consent, construction and operation phases. The success of a development can depend upon correctly identifying impacts and effective consultation and engagement with environmental regulators, the fishing industry and communities.

  • Writing scopes of work for surveys and assessments
  • Collating survey data into reports for submission to the regulators
  • Completing fish ecology and commercial fisheries EIA assessments and producing ES chapters
  • Advising upon fisheries consultation approaches
  • Strategic Planning
  • Development of Policy Guidance
  • Eels Regulations Compliance Assessments
  • Habitats Regulations Assessments
  • Water Framework Directive compliance assessments
  • Habitat restoration and fish passage assessment and design

Fish Passage

Obsolete and engineering-led ‘in-channel’ structures are a major challenge to healthy fish populations and the UK’s compliance with environmental legislation. These can affect many river and estuarine systems due to their impact on flow patterns, sediment transport and fish passage.

Feasibility and design of fish and eel passage solutions are a key area of work for our habitat restoration team. We have successfully delivered innovative solutions to overcome various barriers to fish migration including weirs, culverts, tidal outfalls, pumping stations and hydropower stations in the UK. Our team also work together alongside the UK’s leading fish pass manufacturers to deliver robust and innovative designs.
