Details of specialism

In broad terms I am interested in the ecology and demographics of aquatic organisms, with primary focus on Atlantic salmon (Salmo salar L.). 

Within this broad topic area my particular focuses currently include:

  • understanding wild Atlantic salmon population dynamics
  • international and national assessment of wild Atlantic salmon stocks
  • using indirect methods to study salmon growth, movement and survival while at sea
  • linking otolith microchemistry to movement of individual salmon at sea

Main policy links

  • salmon and recreational fisheries
