1. The effect of environmental contaminants (e.g. endocrine disrupting chemicals) on the behaviour and physiology of fish, particularly fish larvae.
2. The ecology and conservation biology of freshwater fish, particularly salmonids.
3. Individual variation in growth rates in fish: the behavioural and physiological causes and its implications for life history strategies.
4. Freshwater and marine finfish aquaculture: feeding behaviour, diet studies, the physiology of protein metabolism and deposition, new species, selection studies for fast growth/efficient feed utilisation, growth performance in recirculation systems, the effects of stress on physiology and growth, interactions between farmed escapees and wild fish.
5. Fisheries biology and ecology.
6. The use of stable isotopes in the study of fish ecology and physiology
