Ever since I learnt that species loss is occuring 1000 times above the background rate of extinction, my passion for animal welfare was kindled. I received my BSc in Zoology from the University of Bristol and an MRes in Biosciences from Cardiff University. Currently in the third year of my PhD, my research focusses on animal welfare using model fish species and the impact of multiple stressors on susceptibility to disease, physiology and behaviour. The model fish hosts are Guppies (Poecilia reticulata) and Sticklebacks (Gasterosteus aculeatus). Though small and considered less exciting than popular furry mammalian species,  these small fish represent an impressive body of work spanning all key aspects of ecology and evolution.

Since the 2003 discovery that fish can neurologically respond to pain, fish welfare research increased five-fold. Yet fish remain the most neglected of vertebrates when assessing animal welfare. Now, fish welfare is more critical than ever with the global species extinction rate 1000 times above background levels and aquaculture the world’s fastest growing food industry. Demand for food fish is set to increase by 36% from 2006 to 2030 and fish stocks are facing unprecedented stressors to meet this rising demand. Increase in stress levels caused by aquaculture intensification is a known immunosuppressant that increases the chances of fish contracting infections. Currently, aquaculture is facing an ‘infectious disease crisis’ . With lack of effective treatments for many infectious diseases , they are the most significant threat to sustainable development and fish welfare.

Stressors experienced by an animal can be anthropogenic or ecological in nature. Stress and immunity are inherently linked, and this has direct consequences for disease resistance. With infectious disease being a major driver of eco-evolutionary dynamics and the major factor halting sustainable expansion of global animal trade, investigating how stressors impact disease dynamics is essential. Ultimately, my work, in collaboration with the Environment Agency and key stakeholders, aims to improve fish welfare for the pet trade and sustainable aquaculture.
