Current work

My work focuses on the ecology and management of freshwater fish and benefits from a broad, integrative approach facilitated by being undertaken within a Lake Ecosystem Group. Although such work is conducted throughout the UK and overseas, a large component of it involves the continuation of long-term netting and trapping studies of Arctic charr (Salvelinus alpinus), perch (Perca fluviatilis) and pike (Esox lucius) in Windermere, which began during the 1940s and now constitute time series of unparalleled duration, detail and quality. This work is augmented by the use of state-of-the-art hydroacoustics to investigate fish abundance, distribution and size structure, together with aspects of their biotic and abiotic environments. I frequently undertake commissioned research for a wide range of regional, national and international customers.

I also sit on regional, national and international advisory bodies, I have frequent contacts with local and national media, and I am currently the President of the Fisheries Society of the British Isles (FSBI).

Research interests

  • Population dynamics and community ecology of freshwater fish
  • Roles of fish in lake ecosystems
  • Effects of climate change on freshwater fish populations and communities
  • Development of hydroacoustics for studies of freshwater fish and their habitats
  • Conservation of rare fish species
  • Freshwater fisheries management
  • Lake management
