Cefas Weymouth Lab, Barrack Road, The Nothe, Weymouth, Dorset, DT4 8UB, UK
Organisational interests cover
- All aspects of fish health
- All aspects of fish welfare (from capacity of fish to suffer through to health and welfare monitoring on farms) and all aspects of human interaction with fish(fish farming, sport angling, experimentation, ornamental (pet) fish, public display aquaria, capture fisheries)
Specific research interests include
- Stress: non-invasive stress assessment, responsiveness to stressors, links to disease susceptibility
- Fin Erosion: assessment, risk factors
- Stocking Density
